This is the best Interval Timer for HIIT, Tabata & Yoga purposes. I don't normally give review for any app unless it is the best and most convenient. The best thing is you can program it exactly the way you want it to work. Thank you, the app creator! Edit: When the Start Signal for a phase/set/interval is on, the Every X-seconds Signal doesn't work. Please fix this.

Thank you for the great feedback. If there are multiple signals overlapping the app prioritizes certain signals like the default phase signal. You can write an email to lengo.apps@gmail.com with more details when exactly signal does not work for a better analysis of the problem.

I tried out a lot of timers before going with this app. This is the only app I've found that lets me set up a complex sequence of exercises (do these three exercises and repeat three times then do these two exercises and repeat...). In addition, the app has a voice assistant that can speak the name of each exercise, lots of other options, and a clean, modern interface. The developer responded in minutes when I had a question.

I just put up a review (just changed it) insisting y'all add back the sets showing in the corner. After heavy digging I found it's in advanced settings. Really got me there I thought y'all removed it. Appreciate y'all!

You have to disable the "show total intervals" option in settings -> timer customization. Additionaly if you use custom intervals you now can also show sets (rounds) with the new show rounds option. If you have any suggestions on how this feature could be improved, you can also write to lengo.apps@gmail.com
