### 5/5 — Everything you need in an EP

*2026-08-11*

For anything with a fraction of these features, you would expect to be paying a subscription. Not here! This one covers everything you could possibly need in any variety of electric Piano, and it all sounds incredible.

### 5/5 — Another incredible synth from Matthew Fecher

*2026-07-25*

This app picks up where so many other synth apps could have kept going. Absolutely amazing sounds, more presets than you’ll ever use, and packed with features. Worth more than just 5 stars.

### 5/5 — Awesome

*2026-07-17*

This is a pretty cool app I love the appearance also. Good job 👍

### 5/5 — Retro Keys

*2026-06-19*

What an excellent program. Thank you!

### 5/5 — Genuinely Stunning Sounds

*2026-06-04*

One of the most authentic-sounding keyboard apps I've come across. The variety of tones is impressive and every preset feels carefully crafted. Pairs perfectly with a mini MIDI keyboard for a real playing experience. Whether you're writing, jamming, or just exploring, there's something here that will inspire you. Highly recommend to anyone who loves vintage keys.

### 5/5 — A great Rhodes for iPad

*2026-05-30*

I tried a few Rhodes-es on the iPad and was generally underwhelmed. After using AudioKit synth apps, I was excited to try their new e-piano instrument. Their previous Mark 1 app was disappointing in the velocity to timbre response. Retro Keys is totally different and behaves very realistically, the sound is everything you would hope for. Value is incredible compared to some desktop software instruments. I’m not totally sold on some of the fun sound degrading functions, but the layering is genuinely useful. A great sound and highly jammable. Matthew provided personal support when I reached out. Thanks again!

### 5/5 — MUST HAVE

*2026-05-29*

For the price you can’t go wrong. This thing packs so many retro keys you won’t know which one to use

### 5/5 — Awesome sounds

### 5/5 — Excelente

### 5/5 — Fantastic
