Lets make this simple, Ill list all the features this app DOESNT have and you decide if those features are important to you.
1- Ability to customize or import sounds that let you know when to breath in and out.
2- Ability to adjust the breathing indicator volume relative to the volume of music you may have playing in the background on your iTunes or another app.
3- Ability to adjust the length of the inhale portion of the breath relative to the exhale eg: breath in for five seconds out for eight. As it stands, the inhale and exhale can only be the same length of time.
4- An option to have a hold at the top (inhaled) or bottom (exhaled) part of the breath. And with that, of course, the ability to customize the time length and sound indicator to go along with it.
5- ability to set the exact time you want your breathing session to go for rather than the current five minute intervals.
6- ability to set the length of time you need to get to your target breathing rate in any given breathing session.
7- a silent mode that doesnt also vibrate as there is already a so called "vibrate" mode.
8- More than one visual theme would be cool too.
I still give this app four stars cause its pretty and has potential and, to be honest there arent any really good ones out there that Ive found anyway.
