Which devices work with LapperSnapper?

LapperSnapper treats four device families as first-class sources. Every one of them feeds the same analysis engine.

Supported sources

• AiM MyChron 6 — connect your phone straight to the logger's Wi-Fi and download sessions, including engine channels like RPM and temperatures. MyChron 5/5S use the same connection and are expected to work, but aren't yet confirmed on real hardware. See Download sessions from your MyChron over Wi-Fi.
• RaceBox (Mini, Mini S, Micro) — connects live over Bluetooth for high-rate GPS recording. A Mini S or Micro can also hand over the recordings stored on it, or you can import its files afterwards. See Record with a RaceBox.
• GoPro — cameras that record GPS telemetry. Import the video file and you get laps plus footage with a telemetry overlay. See Import GoPro video with GPS telemetry.
• Phone GPS — no hardware at all. See Record your first session with just your phone.

File types you can import

From the Import tab, tap Choose a file:

• .xrk / .xrz / .drk — MyChron / AiM session files
• .ubx — RaceBox recordings
• .csv — phone GPS logs
• .vbo — RaceLogic VBOX files exported from RaceChrono, TrackAddict, Harry's LapTimer, or another RaceBox app
• .mp4 / .mov — GoPro video with GPS telemetry

On Android you can also share a file to LapperSnapper straight from another app — see Share a session file to LapperSnapper from another app.

Phone app vs web app

MyChron Wi-Fi download, RaceBox, and live recording need the LapperSnapper app for iPhone or Android — a browser can't join a logger's Wi-Fi or use Bluetooth. In the web app at app.lappersnapper.com, Choose a file still imports saved logger files; GoPro video import is phone-only.

LapperSnapper is independent and unaffiliated with any hardware maker — your existing gear just works.
