I really like this app. I've used it for more than 5 years at this point, across several phones. It's basic and easy to use--it just works. If you don't care about saving your various interval timers (I don't) you don't need an account. Another bonus, it functions on top of other audio on your phone, so you can listen to a podcast or watch a video and use this simultaneously. The beeps just play over the top of the other audio.

This app is almost perfect! I use it for my firearm training drills and it's very useful. My only complaint is that you can only set timers for whole integers of seconds. I would like the ability to add decimals for 2.5, 2.25 second timers etc. Other than that my only request is a greater variety of options to choose from in the sounds library. Good app, could be improved

Only complaint is you are unable (or I have yet to discover how) to set different time intervals within the same workout--you have to set work time and rest time, wait for it to be completed, then select the next saved interval. I like to do circuits with varying work/rest times, so it probably isn't an issue for someone looking to do more traditional interval training. Still recommend it, just can be a pain for specific scenarios.
