Charge vs Kastyl

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 • 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. • Burn-rate forecasts that warn before you hit a wall: "at this pace you'll run out in about 4 hours." • Cost dashboard: today / 7-day / 30-day spend and tokens, a daily chart, and a per-model cost ranking. • Plan badges and account separation: your plan (Max 20x, Education, ...) is detected automatically, and machines signed in with different accounts get their own cards. • Multi-computer support: see which machine last reported and when, get a heads-up when one stops collecting, swipe to unpair. • Limit-reset notifications and custom gauge thresholds. • Home Screen and Lock Screen widgets, with per-provider and per-account layouts. • 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

Kastyl helps you understand how much usage you have left across the AI tools you use every day. Connect your supported provider accounts and see their usage windows, reset times, account activity, and subscription status without opening each service separately. Home Screen and Lock Screen widgets keep your limits visible when you need them. Live countdowns continue between refreshes, so you can quickly see how much capacity remains and when your usage resets. Kastyl can also send smart reset, pace, and early-reset alerts. With Kastyl Companion, desktop task activity and completion notifications can be delivered directly to your Phone when your computer finishes supported AI task. Your provider sessions stay protected on your device using Apple’s secure storage. Kastyl does not send provider access or refresh tokens to any servers. The relay is used only for the app services required for notifications, device pairing, and companion activity. Kastyl supports Codex, Claude, Cursor, and Antigravity. Provider connections use their official authentication flows, and your provider accounts remain managed by the respective services directly on your phone. Private by design. Kastyl is designed for developers who want a clearer view of their AI usage without manually checking several dashboards. Open the app when you need detail, glance at a widget when you are busy, and let Kastyl keep track of what is left and when it resets. Kastyl is an independent application and is not affiliated with, endorsed by, or sponsored by OpenAI, Anthropic, Anysphere, Google, or any other provider. Provider names are used only to identify the services you choose to connect. Terms of Use: https://kastyl.app/tos Questions? contact@kastyl.app Support: support@kastyl.app
