Description
Create custom countdown patterns exactly the way you like.
After trying several apps and failing to find one that suited all my needs, I decided to write Complex Timer. Initially developed for sport climbing training: intermittend dead-hangs, fingerboard, or strength-endurance methods, it is very useful if you perform sport training methods like HIIT (high intensity interval training), cross fit, cross training, running, tabata, etc.., Also to control your pauses at work, while studying or rehearsing an exam and for cooking.

Good for very noisy or very quiet environments - Add random variation to any Countdown inside the limits you establish. - Navigate to any desired Countdown using a Seek Bar. - Skip back/forward to any moment in the current Countdown, even while running, using a Seek Bar - Mute the nofications while running a Session - Use text-to-speech to know how much time is left or hear the next Countdown description in your own language (contact me if you want your language to be supported) - Share one or more Sessions with other users via email, instant messaging, etc. - Choose between showing the elapsed time or the remaining time for each interval.

Awesome simple app. I use this for a couch to 5k program. I had to add them all manually, but exactly what I was looking for. I use GPS and HR from another app, so just the timers is what I needed. If there was one thing I'd like is to add another warning timer. You only get 1, and I use that for around halfway marks in my runs, but for longer runs, being able to add more say every quarter would be cool.

This timer is completely useless because it doesn't make any sounds! Who would stare at the timer screen when working?

I used to love this timer, nothing else like it. But now that it has "sets" it's effectively broken as you can't move activities around as the "set" doesn't go with it as you move the activity and the app won't let you run it without it being set perfectly. But you also can't delete sets, so if you add an activity then delete it there is a set left over
