10,000 Hours is a simple timer for tracking the time you devote to your goals. Start a stopwatch or countdown, then tap the checkmark when you finish. Each session is saved in your on-device history, where you can add, edit, or delete entries later. One goal is free with unlimited time and history. A one-time purchase unlocks up to five goals, each with separate time and history. Purchases can be restored from Settings or the purchase screen. Features • Stopwatch and countdown timer • Start, pause, resume, and save sessions • Total time and visual progress toward 10,000 hours • View, add, edit, and delete history entries • Direct numeric time entry • Manage up to five goals with one purchase • View your active timer on the Lock Screen and Dynamic Island • Optional local notification when a countdown ends • Restoration after backgrounding or relaunching the app No account is required. Goal names, recorded time, history, and settings stay on this iPhone. There is no advertising or advertising tracking. Apple and RevenueCat are used for purchase validation, restoration and revenue analytics. Goal names and practice history are not sent to RevenueCat. Restoring a purchase restores access only; it does not sync on-device goals or history. 10,000 hours does not guarantee success. But you can keep a record of the time you put in today. Start with your first minute.

Verdict
The clearest difference is update cadence: Dora at every 5 days against 10,000 Hours Timer's every 2 weeks. Dora also leads on device support (3 vs 1). 10,000 Hours Timer's advantage is iOS requirement (17.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.
