ZeroLog Mobile # Your AI. Anywhere. A native Android app for your chats, Compute, jobs and container files. An agent works on the phone itself and asks before each action.

Ran pytest: 2 of 31 fail, both in parse_amount(). Fixed the comma handling. 3. Check on the server: goal not met yet, test_negative_amount still fails. 4. Negative values lost their sign. 31 of 31 pass. 5. Goal met: pytest reports 31 passed. ## What is in the app - **The chat, built in** Chat, chat list, Compute, jobs and container files are drawn by the app, not by a web page inside it. The session key stays in Android's encrypted storage. - **An agent on the phone** Python 3.11, a shell and app control on the device. Each action asks first unless you turn approvals off. - **A folder in step with /work** Pick a folder and it syncs with your container. Files over 400 KB and binary files are left out, never cut short. - **Your container in the Files app** It appears as a storage location, so any "choose a file" dialog can reach it. - **/goal** Name the finish line. The model keeps going until a separate check on the server says it is reached, or that it cannot be. - **Your own CLIs** Claude Code and Codex run in Termux inside a small Ubuntu, about 1 GB. You sign in to them yourself; the app never sees the code. ## Install in four steps 1. **Download the APK** On the phone, tap Download APK and sign in if asked. Chrome warns about every app from outside the Play Store; that is its standard text. 2. **Allow installs from your browser** Settings → Apps → Special app access → Install unknown apps → Chrome → Allow. You can switch it off again afterwards. 3. **Open the file** It installs over 1.17, 1.18 and 1.19 and keeps your settings. 4. **Sign in** The first start guides you. On Android 13 and later, tap the greyed-out accessibility switch once, then App info → ⋮ → Allow restricted settings. ## What it does not do - **It does not read your sign-ins** A command-line tool's login page opens in Chrome; the tool's own callback gets the code. - **Its local bridge needs a key** Tools reach the app over 127.0.0.1 with a key that is new at every start. Other apps are turned away. - **Crash reports without you** The error type and the line in the app's own code. No account, no chat, no device ID. ## The file - **Version** Build 2100, released 13.10.2026. - **Needs Android 8.0 or later** Installs over 1.17, 1.18 and 1.19. - **Download size** The download needs a sign-in. - **SHA-256**: 8210d390bdcc6550568814f9398c4a35a33989433339e1b92970386ec1efe880 - **Previous version**: [zerolog-1.21.7.apk](https://zerolog.ch/zerolog-code-app/zerolog-1.21.7.apk) On a computer, `sha256sum zerolog-2.0.0-a1.apk` must print the same line. ## The ZeroLog family [**ZeroLog** Safety, Privacy and Quality Combined.](https://zerolog.ch/) [**ZeroLog Code** Your workspace, in your terminal.](https://zerolog.ch/code) [**ZeroLog Extension** Your browser, with ZeroLog.](https://zerolog.ch/extension)
