About this app

Beautifully designed Stopwatch and Countdown timer for Android Phones, Tablets and Wear OS Watches

Ticking Sound, Countdown Alarm and Lap Time functionality

Notification whilst stopwatch running in the background on compatible devices.

To save battery the application itself doesn't run in the background, but it simulates it using system events.

This app used to be very good. Now it resets the timer when you switch to another app and opens on the stopwatch, not the countdown. Unless this app is updated and changed back to the way it was, I have to look for an alternative.

My only beef with this app is that I run a pomodoro app alongside this and there may other apps running eg watsapp threads. Sometimes i do not get an alarm at all despite selectingextra long alarm+ vibrate. It is though the app is low priority on my handset which is a bit of a pain if I cannot reply on the alarm actually going off and checking myself. @"geek you up" can anything be done about this?

EDIT: I should have edited this a decade ago (sorry, dev) . Decent app, does what it says. Has some options, like sound for seconds, invert colors, lap times, etc. I had given it five stars, then dropped it to two when the dev got rid of the original app and replaced it with this but the dev made the original available again. I would add options for different watch faces (but that's me). Five stars for no ads (!), no unusual permissions, responsive dev and does exactly what it's supposed to do.
