What's New in Seconds Interval Timer

25.4

October 8, 2026

25.0 No new features this time. This release is maintenance work behind the scenes, and everything works exactly as it did before. 25.1 Creating an account with Google, and signing in with one, work again in the free app. 25.2 The tabs at the bottom of the screen no longer disappear after you edit a timer. 25.3 Apple Watch now fetches your timers and settings from iPhone. Request Sync is at the top of the watch's Settings, and My Timers fetches them the first time you open it. Sync Timers Now has gone from the Apple Watch settings on iPhone. 25.4 Apple Watch now keeps time more precisely than ever, so every interval lands right on the second however long the timer runs.

Subscription fee

I’ve been enjoying using this. If is quite basic and simple. I know it is still being developed.
However, i have switched phones and wanted to continue using this app and it’s making me pay the subscription fee again. It’s not really fair.

I’ve realised I never created an account with the app too. Is there any way possible to allow me to use it on my new phone without paying again?

Очень крутой таймер, много готовых подборок и можно самому создавать, настраивать порядок и разные интервалы. Запускаю одновременно с музыкой, можно прицепить и плейлисты к таймерам, уведомления не прерывают музыку. Дополнительно еще и вид спорта можно добавить и подсчеты для программы «здоровье»

Bait and switch

You can only use your program once, then you have to create it from scratch or pay $8. A developer deserves compensation but $8 is far too dear for what amounts to the essential functionality of an ostensibly free app.

Music to train by

Best app for setting music to each interval of my workout.

Not intuitive and no instructions

I have had this app for YEARS. I can figure out a custom timer but when I know I’m doing a Tabata style workout (which they give you an option for!) it doesn’t make any sense how to set it up or why it should require this much figuring out if I have specifically toggled “Tabata style” on… after years of frustration figuring this out I think I’m looking for something else. I don’t use it often but when I pick it up I don’t want to have to mess around for this long trying to figure things out
