TennisTrkr is a tennis score-tracking app for Wear OS and Fitbit smartwatches, with the core goal of replacing manual scorekeeping during matches. After each point, users simply tap their watch, and the app maintains the current score, server, and sends notifications and vibration alerts for changeovers. It is more of a vertical tool built for a specific sports scenario than a developer tool or platform product in the traditional sense.
The app supports Wear OS 3+ and select Fitbit Versa and Sense devices. Match format configuration is fairly comprehensive, including 3 to 15 games per set, up to 5 sets, whether to use tiebreaks, custom 3- to 15-point tiebreaks, 7-point or 10-point match tiebreaks, and support for rules such as Fast4, Coman Tiebreak, and Ad/No-Ad. For statistics, users can view total points won, break points, break point conversions, aces, double faults, and more. The Fitbit version can also automatically sync sessions as Fitbit Tracked Exercise, allowing users to view workout data such as heart rate, calories, and distance. The Wear OS version provides persistent activity notifications and an always-on display mode.
The official website clearly states that it is a one-time purchase with no subscription, available through Google Play or Fitbit Gallery. The main content does not disclose the specific price, and taxes are shown at checkout based on region.
The advantages are its focused use case and detailed rule coverage, which can significantly reduce the cognitive burden of tracking scores and servers during a match. Fitbit workout data integration also improves the value of post-training review. The drawbacks are that functionality is highly dependent on the watch platform, with inconsistent features across systems. History capacity is limited: up to 3 matches on Fitbit and up to 10 matches on Wear OS. There is no visible information about APIs, SDKs, data export, self-hosting, or an open ecosystem.
It is suitable for users who play tennis regularly, participate in amateur leagues, or need quick scorekeeping on a watch, especially those using Wear OS 3+ or Fitbit watches. Access in China is not specified in the main content. Since purchase depends on Google Play or Fitbit Gallery, actual availability and payment experience in mainland China may be affected by the device ecosystem and store availability, so it is currently rated as unknown.
