I got frustrated with stopwatch apps. They're either bloated with features I don't need, full of ads, or their widgets take up half my home screen.
I just wanted something simple that does one job well. So I built StartStopWatch.
Use the app to run multiple stopwatches at once. Name them, drag to reorder, swipe to delete. That's it.
Or just put a 1x1 widget on your home screen, tap to start, tap to stop. No need to open the app. Put a few on your home screen for different timers.
