Cut my air consumption on every dive

The Air Save mode is a 1:2 inhale-to-exhale trainer and it genuinely improved my SAC rate. Practiced 10 minutes a day for two weeks before a liveaboard and my air lasted noticably longer on every dive. The breathing circle and phase beep keep you on cadence perfectly. Runs continuously with no round limit. Simple concept,gets results.

Not a diver but I love this

I don't dive at all but my freediver friend wouldn't shut up about this app so I tried it. The Box Breathing mode is amazing for anxiety. I use it before meetings and before bed. The circle animation is calming, the haptic taps keep me in rythm, and there's a little sea creature that swims around while you train which is a fun thing to unlock and keep me consistent. Simple, beautiful, works.

Invaluable

I’ve just gotten into freediving and found the whole breathing part really intimidating (because I was rubbish at it!). I’ve since improved so much and I have this app to thank for it. Daily practice is a must and DeepBreath makes that easy and fun that I actually want to practice! Thank you!!

Helpful to get back into diving after some time off

I’ve found this app really helpful to prepare for getting back into diving after years away from proactively diving for recreation and work
