What's New in Periodic Timer

4.7

August 11, 2026

watchOS: - Fixed a bug where the timer was invalidated by tapping the icon at the top of the screen or the Smart Stack activity. Now it's only invalidated when you tap the "Stop" button on Smart Stack, as intended. - Fixed an incorrect value displayed in notifications. - Fixed cropped buttons on Apple Watch Ultra 3. iOS: - New: Haptics on start/stop/pause in silent mode. - Refreshed Settings interface.

Very Deceptive

You’ve paid for the app only to find out you have to pay another $5 to access the features that you just paid $10 for. Total scam. Buyer beware.

Perfect

Does exactly what it says. No nonsense, just does one thing really well. Having push notifications is a great addition.

改善して求む

Apple Watch で周期タイマーを使用している際、周期タイマーをバックグラウンドで使えない。タイマーを起動して、一度文字盤を見て再度起動したらタイマーが終了する。非常に気に入ってるアプリなので改善求めます。

Response from developer

こんにちは。まずはタイマーをご購入いただきありがとうございます！ご安心ください。これはApple Watchの省電力モードによるものです。手首を見ていない間はタイマーの画面は更新されませんが、バックグラウンドで動作を続け、通知をお送りします。

素晴らしい

iPhoneデフォルトアプリのような使いやすさがある。

FAQ

How do I ensure the timer works in the background?

To ensure the timer functions correctly in the background, you must allow notifications for the app. This is crucial for the app to send alerts and maintain its timing functions even when not actively displayed on your screen.

How can I switch between timer output modes?

You can switch between the different timer output modes by simply touching the timer display located at the top of the screen. This allows you to easily select between intervals, total time, or countdown modes as needed for your activity.

What is the 'Shake To Start' feature and how does it work?

The 'Shake To Start' feature allows you to initiate or cancel the timer by shaking your device. This is particularly useful when your hands are occupied, such as during cooking. For this feature to work, the app must be open.

How do I set up persistent notifications for alerts?

To ensure alerts are persistent, navigate to your device's Settings app, then find Periodic Timer > Notifications > Banner Style, and select 'Persistent'. This will prevent alerts from disappearing too quickly.

Is this app compatible with my device?

Based on the provided information, the app is designed for mobile devices and offers features like 'Prevent Lockscreen' and 'Shake To Start' which are common on smartphones and tablets. Specific OS version compatibility is not detailed but it is generally available for mobile use.
