Piru for Android 1.0 — alpha 2

The first Android build of Piru: the iOS app's own code, compiled for Android. It is an alpha, so expect rough edges, and keep an export of your journal.

Install

Download Piru-1.0-a2.apk below and open it on your phone (allow installs from your browser or file manager when Android asks). To get updates automatically, add https://github.com/kageroumado/piru to Obtainium and filter releases by android-.

Every Piru APK is signed with the same key. Before installing, you can check it:

• APK SHA-256: 83fe27dd4092b19fcecb899ca3ef1657072a3a9f7fd1edcfe4bdf77705a80ee6
• Signing certificate SHA-256: 27:83:ED:15:4D:72:8A:E6:93:4B:C2:01:CB:D5:98:2A:13:A3:52:67:C7:97:B5:BB:F7:1C:7C:A5:C1:29:25:48

Android 9 or later, 64-bit ARM.

Moving in

Tools ▸ Data & Backup ▸ Import reads Piru exports, encrypted Piru backups (.piruenc, from iPhone too) and PsychonautWiki Journal's export file, so your history comes with you.

What works

Logging (quick log, My Meds and their reminders), the journal and its timeline, sessions, the library of 1,700+ substances, search, the interaction checker and the other tools, insights, import and export, encrypted backups, English, Spanish and Chinese.

Not in this build

Skins, widgets, the Live Activity, the watch app and Health Connect. A few things look plainer than on iOS: image sharing does nothing yet, and some menus behave like Android's rather than iOS's.

Your data

Your journal stays on your phone. Android's cloud backup and device-to-device transfer are switched off for Piru, and the app asks for no internet access. To move to a new phone, export from Data & Backup.
