Not your average synth app.

055U4RY is very unique and has crazy sounds. It has presets that you can edit and store in a few empty slots. Some controls have unique names that may have different outcomes than normal. The developer is responsive to questions you have. Jacob Haq has a video on YouTube that explains the app better than I can.

Very cool (niche) AU

It’s got a really cool UI, it only has a few presets and controls- but they all compliment the app very well.

Giving it 5 stars because of uniqueness, quality, and pricing.

Absolutely worth the $5.00
