Codexex keeps Codex quota and OpenAI API monitoring together on iPhone and iPad. Sign in with ChatGPT to see your 5-hour and weekly allowance, reset times and provider-reported Codex credits. Accounts that report only a weekly limit get a weekly view. Codex credits are shown separately from API dollars. Connect a standard OpenAI API key to verify API access, or an organization Admin key for usage and cost reports. Optional prepaid balance monitoring uses a separate billing sign-in. Add quota and API balance widgets to your Home Screen. Start a Live Activity for subscription quota on your Lock Screen and Dynamic Island. Readings come from app refreshes; iOS decides when background updates run. Widgets show the last observation and mark older data as stale. Native onboarding, clear account settings, light and dark appearances, larger text support, preview data and local usage history make it easy to get started. Saved API keys and subscription tokens use this device's Keychain. Provider requests run on your device. The optional background wake service receives delivery details, not your OpenAI credentials or quota values. Codexex monitors usage without generating content.

Charge shows your AI coding usage and cost on your iPhone. "How much of my 5-hour window is left?", "Am I close to the weekly cap?", "What did I spend today?" Check it away from your desk, or from Windows, in a glance. Setup takes two minutes. Sign in with Apple, paste the one-line command the app shows you into your computer's terminal, and a lightweight collector securely uploads your usage every five minutes. (Node.js 18+, macOS / Windows / Linux) WHAT YOU GET โข Rate-limit gauges per provider: Claude and Codex out of the box, plus Gemini, Cursor, Copilot, OpenRouter and more through the macOS CodexBar bridge. Reset countdowns included. โข Burn-rate forecasts that warn before you hit a wall: "at this pace you'll run out in about 4 hours." โข Cost dashboard: today / 7-day / 30-day spend and tokens, a daily chart, and a per-model cost ranking. โข Plan badges and account separation: your plan (Max 20x, Education, ...) is detected automatically, and machines signed in with different accounts get their own cards. โข Multi-computer support: see which machine last reported and when, get a heads-up when one stops collecting, swipe to unpair. โข Limit-reset notifications and custom gauge thresholds. โข Home Screen and Lock Screen widgets, with per-provider and per-account layouts. โข Streak heatmap and 14-day cost trend. PRIVACY Charge never sees your prompts, code, or conversations. The collector reads only usage counters and cost data from your local tools and uploads them under your own Apple ID. Unpair a computer any time and its token is revoked immediately. Charge is open source: github.com/baekdusan/charge

Verdict
The clearest difference is device support: Codexex at 3 against Charge's 1. Charge's advantage is iOS requirement (17.0 vs 26.0). On price, review sentiment, update cadence and ads there is nothing between them.
