What's New in Seconds Interval Timer

26.0

October 22, 2026

26.0 - Most of the app has been rebuilt: Home, the timer editors, Templates, Stopwatch, Quick Timer, Settings and the welcome screens are all new. The running timer is unchanged. - The app is now always dark, with an orange accent that the watch app and widgets share. - Stopwatch and Quick Timer work in landscape again on iPhone. - Search on Home finds folders as well as timers. - Apple Watch fetches whatever it is missing from iPhone each time the watch app opens, and runs the preparation interval before a saved timer. - You can run your newest timer as many times as you like, and creating a new timer replaces it. Your previous timers are still listed, and upgrading restores them.

I’ve been using Seconds for years. It’s easy to use. Works over the music in my ears or on my speaker.
