I paid for the pro model, only because the basic app didn’t do simple things like keep your place of where you last left off, no pausing from headphones, etc.
I bought 1 year of the pro, and Audipo could be so much better. There’s no multi device listening, so if you go between and iPhone and iPad it isn’t smart enough to link up to where you ended previously. Also, if you pause with headphones once, THAT’S ALL YOU GET. You get one headphone pause, and then the headphones are unresponsive. Same exact problem with the lock screen.
You also should go in with the mindset of never touching your screen with Audipo open. If a strong gust of wind hits your phone Audipo will jump to one of the many lines while playing your file.
A lot left to be desired, especially for a premium app, but the price is very affordable and I’d buy it every year if these things were fixed!
