Read Suunto Ambit watches and convert to GPX
About this app
AmbitSync is an app to download sport logs (or "moves") from Suunto Ambit GPS watch and convert them to GPX file right on your Android device through the Ambit charging USB cable. No interaction with Movescount website is needed. It also supports Strava upload.
You will only need the Ambit USB cable and an OTG cable (Type-C or Micro-B to Type-A receptacle cable), connect your watch with the Ambit USB cable through the OTG cable to your Android device's USB port. Your device should support USB host mode or this won't work at all.
Note that this app requires network permission just for Strava upload. You may choose not to upload to Strava. The app does not communicate with Movescount at all.
Disclaimer: Although this app does "read-only" access from your Ambit watch, it does not guarantee 100% safe and functional. Also it is not proven to work on any Android devices + Ambit watch combinations.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be idv.markkuo.ambitsync is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.4 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall AmbitSync first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of AmbitSync, and a listing is removed when the evidence for it stops holding up.
