Harry's GPS LapTimer is a lap-timing and in-car data logging app for car and motorcycle track-day enthusiasts, available on iOS and Android. It is not positioned as a general-purpose AI tool, but rather as a specialized tool for GPS timing, sensor capture, video recording, and data analysis in performance driving scenarios. According to the official site, it has recorded a large number of user laps and offers a database of more than 1000 tracks.
Based on the available site content, the product does not disclose any AI models, generative AI features, or machine-learning capabilities. Its core functions focus on automatic lap timing, predictive lap times, win/loss analysis, FullHD video recording and data overlays, plus integration with GPS, OBD, external cameras, and professional sensors. The Petrolhead edition adds video overlays, online live views, and enhanced analysis; the GrandPrix edition further supports high-frequency GPS, engine data, reference-lap video comparison, MultiCam, GoPro HERO, and Sony cameras.
The product uses a one-time paid edition model with in-app upgrades. Rookie costs USD 8.99, Petrolhead costs USD 19.99, and GrandPrix costs USD 27.99; upgrades cost USD 12.99 and USD 9.99 respectively. In some markets, a ToGo edition is available, which can be downloaded for free to view live data and lap times, with a day pass available for USD 4.99 per day. On iOS, there is also a free GPS/OBD Buddy technical demo, but the official site clearly states that it is not lap-timing software.
Its strengths are a very complete feature set for a niche use case, covering timing, video, data, vehicles, and track databases, with support for many external devices. Long-term updates and an expanded refund policy also improve trust. The downsides are that it has no clearly stated AI capabilities, Chinese-language support is unclear, advanced analysis and multi-camera features require higher-tier editions, and distribution is limited to the App Store and Google Play; Android versions below 5.0 are not supported.
It is best suited to track-day users, amateur racers, semi-professional drivers, and anyone who wants to use a phone plus OBD/GPS/cameras to record driving data. Access to the official website from China is unclear, but purchasing depends heavily on Apple AppStore or Google Play. Since Google Play is generally restricted in mainland China, payment and installation may be inconvenient, so we rate it as “partially restricted.” Possible alternatives include RaceChrono, TrackAddict, Garmin Catalyst, AIM Solo, and RaceBox.
