Company profile
researched Aug 2026Wild.AI (operating entity WILD TECHNOLOGIES AI LIMITED, registered at 13 Whitchurch Lane, Edgware, United Kingdom) offers a mobile platform that delivers personalized training, nutrition and recovery guidance adapted to a user's hormonal and biometric patterns. The product set comprises the Wild.AI consumer app and a Coach Dashboard that lets coaches connect to athletes and view logged activity and symptom data in real time. Users complete daily check-ins covering cycle information, symptoms and training sessions; the app visualizes this data in graphs, surfaces individual symptom patterns, and issues day-by-day recommendations on training intensity and duration, pre-, intra- and post-training macronutrient adjustments, and mitigation of menstrual or hormonal symptoms. It also includes cycle-syncable intermediate running training plans and educational content on female physiology.
The platform covers multiple life stages rather than fertility alone: naturally cycling users, users on hormonal birth control, perimenopause and menopause/postmenopause, with the site listing indicative age ranges for each. Wild.AI frames its rationale around published evidence on the underrepresentation of women in sports science and on cycle-related injury risk, citing figures such as 6% of sports and exercise science studies focusing exclusively on female participants (Cowley et al., 2021, Br J Sports Med), up to six-times higher muscle injury risk in the pre-menstrual phase (Ronca et al., UCL 2024), roughly twice as many soft-tissue injuries in specific phases (Frontiers in Sports and Active Living, 2021), and 87.8% of women athletes reporting menstrual-cycle effects on performance (Hayward et al., 2024).
As of 2025 the company states it is part of Zepp Health (NYSE: ZEPP), with website copyright attributed to Zepp Health. Wild.AI experiences run on Amazfit devices, including Amazfit Active and the Amazfit T-Rex 3 Pro, and the about page signals watch-first female-focused experiences planned for 2026.
Founding story
Per the company, Wild.AI was created on the premise that women athletes have distinct physiological rhythms that materially affect performance, and to close a gender gap in health technology where most products treat women as an afterthought or a fertility niche.
Business model
Consumer software: a subscription mobile app (in-app purchases noted on Google Play; reviewers describe an annual subscription and a premium price point) plus a Coach Dashboard product for coaches working with athletes. Following the Zepp Health acquisition, the app is also distributed as an on-watch experience within the Amazfit wearable ecosystem.
App-based subscriptions and in-app purchases; the Google Play listing shows in-app purchases and user reviews reference paid annual subscriptions.
Traction
The company reports its app launched globally in 2019 and that by 2023 it had surpassed 9.1 million check-ins, 7.3 million wearable events and 13.4 million training sessions. Google Play shows 10K+ downloads and a 5.0 rating from about 452 reviews (listing updated 2025-10-24); the company's site cites a 4.5-star App Store rating. Recent Google Play reviews report post-acquisition app instability, broken Garmin syncing and slow support, with one reviewer stating the new owners are limiting updates and not adding new wearable integrations.
Latest developments
Wild.AI is presented as part of Zepp Health (NYSE: ZEPP) as of 2025, with the app available on the Amazfit T-Rex 3 Pro (44mm and 48mm) and further watch-first women's performance experiences announced for 2026. The Google Play listing was last updated 2025-10-24 with bug fixes.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
Positions itself as a female-physiology-first fitness platform differentiated from general fitness apps and from products that treat women's health as a fertility niche; now operating within the Zepp Health/Amazfit wearable ecosystem.
Recommendations are keyed to hormonal rhythm and life stage rather than generic training guidance, with references to underlying research provided alongside guidelines; coverage extends beyond the menstrual cycle to birth control, perimenopause and menopause; and a coach-facing dashboard complements the consumer app.
Technology
Adaptive algorithms described by the company as built on 451+ scientific whitepapers and physiological analysis, translating hormonal state, daily check-in inputs and wearable biometrics into training, nutrition and recovery recommendations. The app integrates with Oura, Garmin, Fitbit, Strava, Apple Health and TrainingPeaks, and runs natively on Amazfit watches (Amazfit Active, T-Rex 3 Pro). The company states it uses encryption, anonymization and opt-in, anonymized research data sharing, and that it does not sell user data; Google Play's data-safety section lists collection of personal info and health and fitness data, encryption in transit, and support for deletion requests.
Go-to-market
Direct-to-consumer app store distribution (iOS and Google Play), athlete and coach testimonials, newsletter and social/community marketing, scientific collaboration for credibility (including work with researcher Dr. Stacey Sims and with PhDs and research groups), and, post-acquisition, embedded distribution through Zepp Health's Amazfit hardware.
Women and girls across life stages — professional athletes, competitive athletes and general fitness enthusiasts — spanning menstruating users, users on birth control, and those in perimenopause or menopause; secondarily, coaches who manage female athletes via the Coach Dashboard.
Geography
United Kingdom-based developer entity (Edgware, England) with an app distributed globally through app stores; parent Zepp Health is listed on the NYSE.
History
The company's milestone timeline dates its origins to 2017, when the foundation of its adaptive algorithms was created from scientific literature review and physiological analysis; the app launched globally in 2019; usage milestones were reported for 2023; the first on-watch Wild.AI experience launched on Amazfit Active in 2024; and in 2025 Wild.AI was acquired by Zepp Health, with new watch-first experiences signposted for 2026.
Risks & controversies
Multiple recent Google Play reviews describe post-acquisition product degradation: app glitches, inability to complete daily check-ins, months-long Garmin sync failures, and unresponsive or unhelpful customer support relative to the subscription price. One reviewer reports being told by the new owners that updates are being limited and no new wearable integrations will be added.
