SignON 0.1.0-beta.3

Get SignON on your Android phone

You need Android 8.0 or newer, a Bluetooth chest strap that sends beat-to-beat (RR) data, and your Intervals.icu API key (Intervals.icu, Settings, Developer Settings).

1. On your phone, open this page and tap SignON-0.1.0-beta.3.apk under Assets to download it.
2. Open the downloaded file. Android asks whether your browser may install apps: allow it (Settings, Apps, Special app access, Install unknown apps), then go back and tap Install.
3. If Play Protect says the app is unknown, choose to install anyway. SignON is not in the Play Store yet, so Google does not know it.
4. Open SignON, paste your API key and tap Save key. Put on your strap, sit down and tap Start.

Updates: download the newer APK from this page and install it over the old one. Your measurements and API key stay.

Had beta.1 or beta.2? This version has a new app ID (work.afternoon.signon), so it cannot update the old one. Uninstall the old SignON first, then install this one and paste your API key again.

Something not working? In Settings you can share a debug log. It contains your heart data from that session (never your API key), so please email it to pm(at)afternoon.work instead of posting it publicly.

What's new in this beta

• The dial grows with your phone: on larger screens it fills most of the width, with the steps under the title and the status right above the buttons.
• The poor contact warning is more compact, so the dial is bigger on small phones.
• New app ID work.afternoon.signon (see above).

SignON 0.1.0-beta.3 for Android 8.0 and newer.
