AI Analysis

●●SolidShip ItSolve My Problem

Clean quota dashboard on Android, but macOS-first CodexBar already fills this niche.

Strengths

•Zero-server architecture: encrypted local storage of OAuth tokens via EncryptedSharedPreferences is solid privacy design.
•Token extraction from CLI config is clever — sidesteps separate login and reuses existing auth infrastructure.
•Persistent notification + Quick Settings tile + background refresh = thoughtful Android platform integration.

Weaknesses

•Narrow audience: useful only for developers who actively monitor three specific quotas on mobile — low market size.
•Derivative port of established macOS tool; no novel insight or differentiation beyond platform change.

Post Description

I ported CodexBar (a macOS menu bar app by @steipete) to Android after getting tired of opening three browser tabs to check whether I'd burned through my quotas.

It monitors Claude, Codex (ChatGPT), and Gemini usage in one place — persistent notification, Quick Settings tile, background refresh, and push alerts on reset.

A few notes: - Uses the same OAuth endpoints the CLI tools rely on, so you extract tokens from your local CLI config (no separate login flow) - No backend server. All tokens stay on-device in EncryptedSharedPreferences - Gemini needs 4 values because Google OAuth requires client ID/secret for refresh

Pre-built APK on the Releases page if you want to try it without building.

Happy to answer questions about the token extraction or the Android architecture.
