Best out there

15 years later, it is still the best interval trainer out there. Timer groups, Timers, intervals, and activities within them means this is the most versatile app of its kind. It needs Apple Watch support and text to speech (although the record voice works as a a great alternative). But this app should not have been abandoned. It’s the gold standard.

Needs to connect too Apple Music

Great app. Needs to connect to Apple Music. Also needs to fix the orientation from upright to side

Best timer on the market

100% customizable, including with user recorded sounds. Has a random interval setting. Allows timer groups, timers, then sets, then actions with in sets, all of which can be customized. Nothing on the market is as flexible. Great for mma, boxing, grappling drills, or any type of interval trainer.

Just needs an Apple Watch app.

Exceptionally useful

I am a professional martial artist and have used Ultra Trainer for years. Yeah, there’s a bug or two but there is no other random interval timer in existence that I know of, and it’s invaluable for solo training with a heavy bag. You record whatever combos you want and then while you work the bag UT makes you do them at random times. This is a game changer for building reaction time and adaptability. Without the app, you do a combo when you’re ready on your time, but with it you are forced to react just like you would to changing circumstances in a fight. I wish there was a dedicated hardware unit that would do the same thing but as is, Ultra Trainer does it’s job admirably. If you are concerned with it’s integration with your music library, you aren’t training hard enough! Thanks devs. Superior product that fills a real need.

Great app for workouts but developer appears to have stopped updating it

I love this app. It's one of my top apps I use for my training and workouts. But it would seem the app is no longer receiving updates. It has some bugs in it now that I would love to see fixed but isn't getting done. Because of that, I can only give 4 star rating even though this is a 5 star app
