First steps
Start with a little care.
The Android preview will open first to invited testers. A shared postcard does not automatically grant install access.
Preview access is being prepared.
There is no active tester install link here yet. When access opens, the invitation will identify the eligible Google account and the correct installation.
Check your invitation.
Use the Google account added to the tester list. Open the supplied Play opt-in link, join the test, then follow its installation instructions. The app may not appear in Play search during internal testing.
The website cannot check your account's eligibility.
Protect an existing journey.
If you already use an Embertrail preview, keep it installed and contact the developer before switching packages. Matching the app name is not enough to preserve a save. Do not uninstall or clear data to resolve a signing or install mismatch.
Before changing phones or uninstalling, use Backup & restore in Help or Privacy to save a portable journey file outside the app. Review the file before confirming restore; totals replace the current journey and step syncing pauses until reconnect. There is no automatic cloud restore. A different distribution package can still start a separate journey.
Try the demonstration.
Android 14 or newer is required by the current phone candidate. Explore the demonstration first; simulated steps do not advance your real journey.
Connect a step source when ready.
Allow Steps read and write access in Health Connect for phone reports and measured watch imports. A supported Wear OS companion is optional. Health Connect can combine reports from available health apps; it is not necessarily a phone-only total.
From the next full local day after the first measured watch interval, Health Connect combines phone and watch coverage using your source priority. The first partial day keeps the higher-report fallback. Separate daily totals are never added, and the saved starting reference is preserved, so today’s displayed total can differ from progress added to the journey.
Return and sync.
Reopen Embertrail after walking. Reports may arrive late or be corrected. Phone motion cues can animate the traveler but do not create saved steps.
If access is unavailable, your saved journey stays on the device. Check Android's Health Connect settings rather than clearing the app.
