Not all app categories can boast the same degree of user retention on day 30. While news apps were reported in the third quarter of 2024 to have a retention rate of almost 10 percent, social media apps presented less than two percent retention rate after 30 days from install. Entertainment apps presented a three percent installation rate, while a shopping apps had a retention rate of around four percent one month after installation. Before retention: user acquisition Gaining new users is fundamental for the healthy growth of a mobile application, and app developers have an array of tools that can be used to expand their audience. As of the second quarter of 2022, CPI, or cost per install, was the most used pricing model for user acquisition campaigns according to app developers worldwide. The cost of acquiring one new install in North America was of 5.28 U.S. dollars, but driving in-app purchases in the region was more pricey, with a cost of roughly 75 U.S. dollars per user. The future of in-app advertising In recent years, subscriptions and in-app purchases have become more popular app monetization practices, with users finally willing to pay for app premium functionalities and services. In 2020, video ads were reportedly the most expensive type of ads to drive conversions on both iOS and Android apps, while banner ads had a cost per action (CPA) of 36.77 U.S. dollars on iOS, and 10.28 U.S. dollars on Android.

During the third quarter of 2020, Finland was the country with the highest app retention rate, with *** percent of the users who first launched the app ** days prior still using it. Japan ranked second, with a ** day post-install app retention rate of **** percent, while Ireland ranked third with a **** percent retention rate. Egypt, Turkey, and India ranked last with a ** days app retention rate between **** and **** percent in the examined period.

iQIYI and Tencent Video are the leading user-generated video platforms in China. In the third quarter of 2022, iQIYI's 30-day retention rate reached **** percent. In comparison, the figure of Youku stood at **** percent, much lower than other domestic rivals. The company merged with the well-established video sharing site Tudou in 2012 and was acquired by Alibaba Group thee years later. Alibaba utilizes the platform to facilitate its e-commerce sales.

In 2024, libraries and demo apps had the highest retention rate among Android users worldwide. Apps in this category registered a 48.31 percent retention rate after one day from install, which dropped to 20.88 percent after a month. Comics apps followed, with a 47.56 percent retention rate on the first day after install, which experienced a decrease to 20.46 percent after 30 days. Android events apps, as well as weather apps, presented a retention rate of less than 20 percent after 30 days from the first install as of the examined period.

According to adjust, the 30 day retention rate of a paid install of a payment app was only 3 percent. For organic installs of payment apps, the 30 day retention rate was six percent. During the first half of 2019, global payment app retention rates were lower than on other verticals.

The 30-day (D30) retention rate of mobile gaming users can vary greatly between different mobile gaming genres. Among iOS users in the United States in 2023 and 2024, match games ranked first for user retention. In contrast, shooter, and action games all had a user retention of under three percent past the 30-day mark.

In March 2020, the total sessions on mobile apps worldwide spiked at ***** percent, while retention after 30 days from the first install recorded its lowest rate in the examined period. Due to the global outbreak of coronavirus pandemic, engagement with mobile apps skyrocketed in 2020. However, the share of users who opened the app after 30 days from the first install *********.

The statistic shows the mobile app retention rates in Southeast Asia in 2019, broken down by app category. That year, mobile users showed a app retention rate of ** percent on the first day for gaming apps. On the 30th day, the retention rate was highest for social apps.

The lack of a reliable and innocuous mark-recapture method has limited studies that would provide essential information for the management of commercial sea cucumbers. Tagging sea cucumbers is notoriously difficult because of their plastic nature and autolysis capacities. The markers that have so far been tested, mainly on or through the body wall, were either lost rapidly or had major drawbacks (e.g. suitable only for batch identification, requiring complex analysis, causing infections, necrosis, behavioural changes and mortality). The present study explored the efficacy of passive integrated transponder (PIT) tags for individually marking sea cucumbers by assessing retention rates and long-term side effects of tags inserted in previously unstudied tissues/organs. Individuals of the species Cucumaria frondosa were tagged in the body wall, aquapharyngeal bulb and at the base of the oral tentacles. They were monitored closely for evidence of stress, infection, change in feeding and spawning behaviour and tag retention rate. Implanting the tag in an oral tentacle to reach the hydrovascular system of the aquapharyngeal bulb achieved the best retention rates in full-size individuals: from a maximum of 92% after 30 days to 68% at the end of the experimental period (300 days). Efficacy was lower in smaller individuals (84% after 30 d and 42% after 300 d). Following a slight increase in cloacal movements for 15 h post tagging, no side effect was noted in sea cucumbers tagged in the aquapharyngeal bulb via the tentacles. Feeding and spawning behaviours were not affected and no signs of infections or abnormal cell development in the vicinity of the tags were observed. This study indicates that marking sea cucumbers with 8.2 mm long PIT tags implanted via the oral tentacle is an effective technique, yielding relatively high retention rates over long periods without any detectable physiological or behavioural effects.

Few studies have investigated the encapsulation of apigenin in solid particle-stabilized emulsions. In this work, Pickering emulsions containing apigenin and stabilized by whey protein isolate-chitosan (WPI-CS) complexes were created to enhance the bioavailability of apigenin. Different lipids including medium-chain triglycerides (MCTs), ethyl oleate (EO), and corn oil (CO) were selected to fabricate lipid-based delivery systems. The microstructure of the Pickering emulsions, as revealed by optical and cryo-scanning electron microscopies, showed that the oil droplets were dispersed evenly and trapped by a three-dimensional network formed by the WPI-CS complexes, which was further confirmed by rheology properties. After 30 days of storage, Pickering emulsions with MCTs achieved the highest apigenin retention rate, exhibiting 95.05 ± 1.45% retention when stored under 4°C. In vitro gastrointestinal tract experiments indicated that the lipid types of the emulsions also affected the lipid digestion and release rate of apigenin. Pickering emulsions with MCTs achieved a higher bioaccessibility compared to that of the other two emulsions (p < 0.01). These results indicate that the delivery system of Pickering emulsions with MCTs stabilized by WPI-CS complexes offers good storage stability and improved bioaccessibility of apigenin.

Market Dynamics of the Over-the-Top Content Market

Key Drivers for the Over-the-Top Content Market

The growing demand for Regional content is fueling the expansion of the OTT market’s industry. 

Regional OTT platforms are swiftly gaining ground in India’s streaming market with tailored, localised content. Promotion of regional content like mythological and historical tales, content produced in regional languages, dedicated regional platforms,and availability of subtitles in regional languages are aiding in the surge. According to a FICCI-PwC report, the share of regional language consumption on OTT platforms will cross 50% of total time spent. The share of regional language OTT titles increased from 47% in 2021 to 52% in 2023. Content has started to travel across language barriers; industry discussions indicate that between 20% and 50% of consumers now consume content in more than one language using subtitles and dubbed versions. OTT platforms desirous of a national reach will require focusing on at least eight to nine languages. For instance, (2024, In India, the viewer base has surged to 347 million, with a staggering 60% of content consumption coming from regional languages. Telugu leads the pack (15%), followed by Tamil (13%), Malayalam (8%), and Bengali (7%). Smartphones have become the dominant device for streaming, accounting for 70% of all viewership

Increased streaming of live sports and events is accelerating the growth of the OTT market 

OTT platforms such as DAZN, ESPN+, and Amazon Prime Video have rapidly grown in popularity by delivering a seamless, on-demand viewing experience that appeals to modern sports fans. For instance, Netflix’s foray into live sports has yielded substantial subscriber growth. The platform attracted 1.4 million U.S. sign-ups for the Jake Paul vs Mike Tyson fight and 700,000 for NFL Christmas Day games in 2024. While retention rates were slightly below the platform's average, they still outperformed competitors like Paramount+ and Hulu. Netflix continues to expand its live sports offerings, securing deals with WWE and exclusive rights for the FIFA Women’s World Cup in 2027 and 2031. The IPL’s media rights for 2023-2027 were auctioned for approximately US$6.2 BILLION, SURPASSING THE Premier League to become the second-highest-valued sports media property worldwide, behind only the NFL. By 2025, the number of US viewers who stream a sports event at least once a month is projected to rise to over 90 million — a steep rise from 57 million in 2021. This reflects the immense value and revenue potential of live

Key Restraints for the Over-the-Top Content Market

The growing issue of Content Piracy continues to be a significant restraint on the expansion of the OTT market. 

According to Viacom18 Digital Ventures in 2021, every piece of content is pirated and it affects anywhere between 25-50% revenue of OTT platforms. This is substantial given the significant cost of content that they carry and investments they make, he said. In Intellectual property, copyright comes under the most important part as it gives the creator the right to produce work in literary and artistic work rights like creating and publishing books, films, paintings, music, & databases. In addition to breaking intellectual property laws, these piracy cases cause service providers and content producers to suffer enormous financial losses. Advertising and subscription-led video streaming services are losing up to 30% of their annual revenue to piracy as more and more Indians log in to digital platforms to watch content. Popular shows such as Scam 1992 on Sony LIV and Ashram on MX Player have seen pirated versions surfacing within half an hour of their launch (2021). Platforms must also navigate issues related to censorship and regulatory compliance, as seen with recent controversies arou...

BackgroundA dysbiotic vaginal microbiome (VMB) is associated with clinical conditions such as bacterial vaginosis (BV) and an increased risk of human immunodeficiency virus (HIV-1) infection. Considering the high prevalence of BV among African, Caribbean and Black (ACB) women, we conducted a prospective, randomized, open-label phase 1 clinical trial to determine the feasibility, safety and tolerability of administering low-dose estrogen, probiotics or both in combination to improve vaginal health and decrease HIV-1 susceptibility.MethodsACB women aged 18–49 from the Greater Toronto Area (GTA) were randomized to one of four study arms: intravaginal estradiol (Estring©; 7.5mg/day); a vaginal probiotic (RepHresh™ Pro-B™) administered twice daily; a combination of Estring© and vaginal RepHresh™ Pro-B™ (twice daily); or the Estring© and oral RepHresh™ Pro-B™ (twice daily), for a duration of 30 days. Feasibility was evaluated through enrolment, retention, and adherence rates, while safety and tolerability were determined by a pre- and post-treatment blood panel and reported adverse events (AEs).ResultsOverall, 63 ACB women were screened, 50 were enrolled and received the intervention while 41 completed the study, resulting in 80% enrollment and 82% retention rates. Overall adherence to the study protocol was high at 93%, with an adherence of 92% for RepHresh™ Pro-B™ and 97% for Estring©. A total of 88 AEs were reported by 29 participants which were mild (66/88; 75%) and largely resolved (82/88;93%) by the end of the study, with no serious AEs (SAEs) noted. In addition, a panel of safety blood markers measured pre- and post-intervention confirmed no clinically significant changes in blood chemistry or blood cell count.ConclusionOverall, the administration of intravaginal estrogen and/or probiotics in pre-menopausal ACB women is feasible, safe, and well tolerated.Trial registrationThe trial was registered with Clinicaltrials.gov (NCT03837015) and CIHR HIV Clinical Trials (CTN308).

As of April 2020, mobile users in Latin America showed a retention rate of 29 percent on the first day after they installed a shopping app. After 30 days of installing it, the retention rate had dropped down to five percent.

We examine the hypothesis that reef fish larvae have some direct influence on their own dispersal and ability to recruit to their natal reef by tracking cohorts of bicolor damselfish (Stegastes partitus) from hatching to settlement onto the reef, about 30d later. We conducted high-resolution sampling during two consecutive years in a small area (15 km x 20 km) off the west coast of Barbados, extending from depths of 0 to 100 m. Observations of discrete stage-specific larval patches of mean size of 29.4 and 13.2 km^2 for preflexion (1-5-d old) and flexion/postflexion (>5-d old) stages extending ca. 30 m in the vertical indicated that larvae initially dispersing as patches tend to stay in coherent patches throughout their pelagic duration. Highest concentrations of preflexion larvae within a patch were in the upper 20 m, while those of older larvae were always deeper. Downward migration of about 60 m throughout ontogeny within stratified currents represented a retention mechanism for locally spawned larvae. Most of the variability in estimated retention rates between daily cohorts occurred during the earliest stages as a result of the dynamic nature of surface currents experienced by larvae prior to the onset of vertical migration. Differences in residence time between experiments were consistent with observed intermonthly variability in recruitment strength, implying that pelagic processes can explain recruitment rates. These results provide empirical evidence for larval retention of coral reef fishes and stress the role of active behavior in larval transport. "Our main objective was to investigate the mechanism by which coral reef fish larvae may maximize their return to the settlement habitat of the natal population. For this purpose, we needed to determine the role of larval behavior in controlling dispersal and horizontal advection and it relationship to the island-scale flow patterns."

Monitoring individuals within populations is a cornerstone in evolutionary ecology, yet individual tracking of invertebrates and particularly parasitic organisms remains rare. To address this gap, we describe here a method for attaching radio frequency identification (RFID) tags to individual adult females of a marine ectoparasite, the salmon louse Lepeophtheirus salmonis. Comparing two alternative types of glue, we found that one of them (2-octyl cyanoacrylate, 2oc) gave a significantly higher tag retention rate than the other (ethyl 2-cyanoacrylate, e2c). This glue comparison test also resulted in a higher loss rate of adult ectoparasites from the population where tagging was done using 2oc, but this included males not tagged and thus could also suggest a mere tank effect. Corroborating this, a more extensive analysis using data collected over two years showed no significant difference in mortality after repeated exposure to the 2oc glue, nor did it show any significant effect of the tagging procedure on the reproduction of female salmon lice. The RFID tags were lost linearly over time, with the percentage of the living female population that retained their original tags declining by 0.28 percent.day^-1. In other words, tag retention was in general high, with a typical projected retention of about 89% after 30 days or 80% after 60 days, although one of the four batches of glue used, purchased from a different supplier, appeared to give significantly lower tag retention and with greater initial loss (70% and 53% respectively). Overall, we find that RFID tagging is a simple and effective technology that enables documenting individual life histories for invertebrates of a suitable size, including marine and parasitic species, and that it can be used over long periods of study.

IntroductionSeveral treatment guidelines for Parkinson’s disease (PD) had been proposed in recent decades. The aim of current study was to investigate the initial medication utilized in newly diagnosed PD subjects in Taiwan during an eleven-year period.MethodsA total of 7,550 patients with newly diagnosed Parkinsonism were retrospectively enrolled from the National Health Insurance Research Database of Taiwan from 2000 to 2010. After excluding patients at risk of secondary or atypical Parkinsonism, those never receiving medication or having incomplete data, 1,645 subjects were included. The participants were then divided into four treating regimen groups, namely levodopa (LD) only group, dopamine agonist (DA) only group, LD+DA group, and No-LD, No-DA group. The demographic data and medication retention rate were compared across the four treatment groups.ResultsLD only and No-LD, No-DA regimens were the main initial choice of PD treatment in Taiwan. LD containing drugs were more often prescribed to the elderly population than the other two treatment regimens, while No-LD, No-DA medication was the major initial choice for younger patients. DA only regimen occupied only 3–4% of the initial PD prescriptions and was given predominantly by neurologists. Over the eleven-year period, there is a trend for the middle-aged population to receive medication containing LD as initial treatment. The one year retention rate of anti-Parkinsonism medication was around 30–50% in our population. Age, polypharmacy, change of one-year daily levodopa equivalent dosage and newly onset of dementia, stroke and psychiatric diseases all affect drug compliance in PD patients.ConclusionsThis is the first long-term study to explore initial pharmacotherapies in an Asian PD population. We hope to provide evidence for adjusting government policies and public education of physicians and PD patients in the future.
