Not quite there yet
Seemed really useful based on description, but was a bit of a disappointment after trying out. The main problem was multiple bugs I encountered. “Done” button upon naming a new project was hidden bellow the keyboard and enter did not work either. The only way to get past was to use only the automatic random naming. It could have been ok, if it was possible to rename the project afterwards, but it wasn’t. Uploading previously stored tracks from my Creative Cloud drive ended up having the first 4 tracks I uploaded for all different projects no matter which files I chose. I had to copy the files from CC drive to Dropbox and then upload to get it work. Op.fun browser kept crashing the app constantly, making it basically impossible to use. I was also hoping for the trim function to work on individual tracks or ideally on multitrack export, but it seemed to be only working on stereo bounce which flattens all tracks to one. Multitrack export to AudioShare only exported the first track, making it useless. I would imagine that being quite important workflow for many iOS-music producers. Without the bugs it would be really useful, but in the current state not worth the price.
