2025 was a year of rapid growth for Treelet Health as we walked hand in hand with our users. We have always adhered to the original aspiration of "quickly responding to needs and polishing precise experiences", and with a rhythm of high-frequency iterations, we have transformed every piece of user feedback into every upgrade of the product. From the in-depth optimization of core health functions to the comprehensive adaptation of device linkage, and then to the interesting upgrade of interactive experience, every version this year embodies our pursuit of "making health management easier and more warm".
I. Upgrade of Core Health Capabilities: From Data Recording to Accurate Interpretation, More Professional Protection
In 2025, we continued to deepen the accuracy and practicality of health data, gradually upgrading the product from a "data recording tool" to a "personalized health assistant":
- Expansion of multi-dimensional health functions: Added a hearing test function, which supports reading Apple Health hearing data through AirPods combined with the Hughson-Westlake ascending method, providing users with a reference for their daily hearing status; launched a stress index assessment function, which comprehensively judges physical and mental stress status by integrating multiple health data; added a mood card recording function, which can automatically generate a weekly average mood report to help users review emotional ups and downs.
- Continuous polishing of core algorithms: For the two core indicators of blood pressure and blood sugar, multiple algorithm iterations were completed - from the optimization of a single model to a mixed calculation mode of more than 3 self-developed algorithms, continuously improving data accuracy; fixed blood sugar calculation errors, fine-tuned the blood sugar prediction model, and optimized the interpretation logic based on users' real data to make health references more reliable; at the same time, optimized the cardiovascular physiological load index algorithm and sleep score evaluation system, added the average deep sleep duration indicator, and scientifically quantified health status from multiple dimensions.
- Optimization of sleep monitoring experience: Self-developed sleep calculation model, breaking through the limitations of Apple's sleep system, accurately capturing nap data; fixed errors in total sleep duration and segment calculation, upgraded sleep scoring rules (staying up late and getting up late will deduct points), making sleep assessment more in line with the real rest status.
- The annual health report was grandly launched: The 2025 Annual Health Report was launched, presenting the annual health status in an interesting way - converting walking distance into marathon/earth circumference, heart age assessment, sleep duration compared with polar bear hibernation, ton-level water intake statistics, etc., making every piece of data a vivid witness of users' health protection.
II. Device Linkage and Experience Optimization: Breaking Scene Restrictions, More Convenient to Use
We focused on users' needs in multiple scenarios, continuously optimized device adaptation and interactive experience, and integrated health management into daily life:
- In-depth adaptation of Apple ecosystem: Optimized the interface of iOS desktop widgets such as water drinking and health data, supporting direct viewing/recording of data on the desktop; Apple Watch functions were continuously upgraded, adding four-corner dial styles, and circular dials can add widgets such as blood pressure, blood sugar, water drinking, and early warning, with key data visible at a glance; the new version of the Watch app was launched, with clearer and easier-to-read data display; added iCloud synchronization function, automatically synchronizing data such as badges, points, tasks, and friend lists across devices, eliminating the need for manual migration when changing devices.
- Upgrade of interface and operation experience: Reconstructed the UI of the three major Tab pages: Today, Psychology, and Physiology, sorted out and merged redundant data indicators, keeping all data dashboards while making the pages more concise and data easier to find; unified font styles, optimized page scrolling fluency, added slight animation loading effects on the homepage, making the visual and operation experience more comfortable; optimized the splash screen advertisement experience, continuously guaranteed the ad-free rights of subscribed users, and fixed ad loading interaction problems on specific models.
- Optimization of personalized reminders: Upgraded the water drinking reminder logic, bid farewell to "warning only when缺水", and changed to precise reminders according to scenarios (such as a cup of coffee in the morning, a cup of warm water before going to bed), making the water replenishment habit more in line with daily life; improved the new user guidance on the physiological page, taking into account the use scenario where male users care about their partners, making the function more warm.
III. Improvement of Interaction and Welfare System: Making Persistence in Health More Motivated
In order to make "persisting in health" no longer boring, we built and improved the interaction and welfare system in 2025, using fun and rewards to stimulate users' motivation:
- Check-in points system launched: Added daily/weekly check-in tasks, and points can be earned by completing challenges; launched point redemption benefits, supporting redemption of VIP memberships, and at the same time, users can participate in lucky draws - having the opportunity to obtain limited "Treelet Doctor" cards (including rare SSR versions, each with an exclusive number) and 1-7 day, monthly, and annual memberships; specially optimized membership rights, and permanently subscribed users can give the membership redemption codes obtained from lucky draws to others, making health benefits shareable.
- Continuous upgrade of membership rights: Subscribed users can unlock the advanced version of "Treelet Classmate" and obtain more accurate health suggestions and data analysis; at the 100th version milestone, a limited-time discount activity for lifetime membership was launched to thank and回馈 long-term supporting users, which is also the first time the product has launched membership discount benefits.
IV. Basic Experience Guarantee: Polishing Details, Stable Escort
In the annual iterations, we have always attached importance to the stability of the basic experience, and have fixed many known problems: focused on fixing multiple fatal bugs to clear core usage obstacles; solved occasional problems such as page loading stuck, data synchronization delay, and adaptation of specific models; improved multi-language adaptation, allowing users in different regions to use it easily; continuously optimized APP performance usage to ensure smoother page switching and data loading.
V. Core Logic of 2025 Iteration: Every Upgrade Originates from Your Feedback
Looking back at the high-frequency iterations in 2025, every upgrade direction of ours is inseparable from the real needs of users: when users said "the homepage data is too messy", we reconstructed the UI; when users feedback that "nap measurement is inaccurate", we developed a self-developed sleep model; when users asked "what can points be used for", we launched the redemption and lucky draw system; when users hoped "it is convenient to use multiple devices", we improved iCloud synchronization and Watch adaptation.
From the 100th version milestone commemoration to every subsequent small version focusing on details, from major breakthroughs in core functions to minor adjustments in interface interaction, 2025 of Treelet Health was a year of joint polishing with users.
VI. 2026 Outlook: Original Aspiration Remains, Continue to Walk Together
The growth of 2025 has come to an end, but the journey of guarding health continues. In 2026, we will continue to focus on user needs, and deepen in the directions of precise health analysis, personalized function customization, and multi-scenario health services, making Treelet Health a more understanding and intimate health partner.
