brilliant but insane. It works great, but once I've started the timer it's impossible to go back and adjust the interval times, there's no 'settings' button, nothing, this is driving me insane, I might have to find another timer. Edit - I've found a way, I have to kill the app, open the app, and then press back button. Would be much easier if there was a settings button.

I downloaded 4,5 timers and this is by far the best. I use it for a 30 minutes yoga stretches. The clean interface is very nice to read. The chimes are soothing to hear. The best part for me is the app will resume to where you left off if you've closed the app. No ads at all One thing I want is if I can sync my data between 2+ devices. I paid to support the devs. Thanks guys!

Perfect app. I've been using it for Japanese walking / interval walking and it is the perfect app for this. It lets you set intervals, how many and lets you set a rest period between if you need. The alerts are unobtrusive and the app works in the background with spotify/youtube music playing in the foreground or with the screen off. Thanks so much for this great app!
