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 Appleβs 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

Verdict
The clearest difference is ads: Kastyl at none against UsageScope's shown. Kastyl also leads on update cadence (every 2 days vs every 5 days) and iOS requirement (18.0 vs 26.0). UsageScope's advantage is device support (3 vs 1). On price and in-app purchases there is nothing between them.
