Given this app is still actively developing, maybe I can suggest … to use some images (for example, a spinning circle, or flower, some visual things) ? It is using text like ‘inhale exhale sustain ‘ which are very effective already! Good job!
The most beautiful thing in this app is - it can be quiet (no music, noise, songs), and has great clear haptics/vibrations signals, so users can close eyes and feel the breathe tempos clearly with its various strengths and haptics patterns! It is a very considerate design!
It is good that the UI is simple and concise, no ads, no distractions, very centric on providing best meditation exercise! Very nice app!
I will definitely keeping the premium subscription, and hope developers continue polish it, so more people can see its value!
