Acid

★★★★★ Using on a Samsung S9 it fails to fill the screen properly, occupying a postage stamp sized portion of screen center (you can stretch but...) but it does sound great, and you can get a great acid sound in seconds which is fantastic. Some of the knobs work in an inverse fashion, oddly. Sort out the screen size and add MIDI export and this is an excellent little tool together something out of your head and into ears. Worth the full 5 stars if these niggles are sorted.

★★★★★ Buggy but fun! This one has a lot to work out in the interface, and I'm running into strange buffering problems with the audio if the knobs turn past their intended range. Which is easy to do because the knobs turn endlessly, extending the range of some parameters much further to the extremes than you would find in almost any 303, even an emulation. The upshot is there is some very strange and interesting territory to be explored near those boundaries beyond which the audio becomes unusable. Worth the technical difficulty.

★★☆☆☆ I'm giving a one-star review to hopefully get the devs' attention, but I doubt itll work. The app is good at making baselines, I used to like it and incorporate it into my work. But this app has had a problem crashing when u try and save for at least a year now, at least! And many times ive lost beats, ive even had to shut down and restart my phone, sometimes it would remain unresponsive for 10–15 minutes! What if then I needed to call 911? Now yes its free but that's no excuse to leave a bug on th

★★☆☆☆ As a cheap and cheerful substitute of a rebirth type software package It's alright to mess about on, and it sounds pretty good. You can produce some filthy acid sequences and filter the hell out of them. However, the interface is not very user-friendly and is a nightmare trying to program notes.... Particular when you drag and pinch to enlarge the sequencer screen sometimes it doesn't stop enlarging to the point of filling the entire screen and then being unable to minimize it again.having to then log out and lose the progress you've made. However, it is good fun and even in the free mode you can record your tracks and then export them into other music apps. A few tweaks here and there would greatly improve the usability.

★★☆☆☆ What is this? Nothing but crackling and no instructions. Doesn't seem to do anything useful at all or am I missing something.
