I love this app and in comparison to all other pranayama apps this is the most suitable in my opinion for a serious practice. Nothing unnecessary, everything is just enough and you can fit it to your own needs. It’s very beautiful and mindful and it’s a great pleasure to use it! The developer is very friendly and supportive and is open to suggestions. Being someone who learned anulom vilom by books 16 years ago and counted seconds in my head or by heart bits, for me this app is an astonishing discovery. It has a metronome and you can choose a sound of it, as well as notifications when to inhale or exhale or suspend the breath. There are lots of breath sequences to choose from and it is very easy to set up the duration and the rhythm of pranayama. You can set up your own training plan and set up reminders for it, they come up together with nice encouragements.
