A simple and beautiful interval timer. 1. Drag to set your custom intervals for workout, rest, rounds, etc 2. Tap to start. Interval Timer doesn't interfere with your music or other apps: ∙ Listen to your music apps while you work out. ∙ Voice or beep guides for every workout. ∙ You can leave the app and still listen to the audio guides, in order to follow a workout you found online. And no need to manually record your workouts: ∙ Detailed history and statistics pages to track your progress. ∙ Repeat a previous workout from your history, so you don't need to set it again. If you have any ideas for how to improve the app, just tap "Contact Support" inside the app and let us know! We are always trying to improve Interval Timer. This app offers an optional auto-renewable subscription, Premium Pass (monthly), and a one-time Lifetime Pass. Premium Pass starts with a 1-week free trial for eligible new subscribers, then renews automatically every month at the price shown in the app until you cancel. Payment is charged to your Apple Account when you confirm the purchase or, with a free trial, when the trial ends. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for the renewal within 24 hours before the end of the current period. You can manage the subscription and turn off auto-renewal at any time in your Apple Account settings. Cancelling stops the next renewal, and Premium stays active until the end of the period you've paid for. Any unused part of a free trial ends when you buy a subscription.

Sperrstunde helps you go offline at night and keep your evening calmer. Choose the apps that usually keep you scrolling, set your active nights and define your block window. Sperrstunde then blocks your selected apps automatically during that time, so a quick look does not turn into another long session. You stay in control: - Choose only the apps you want to block - Set your own sleep and wake times - Pick the nights Sperrstunde should be active - Pause a night when you really need to - Change your selection anytime Sperrstunde is built for evenings, sleep routines and calmer nights. Everything outside your selection stays usable. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
