### 5/5 — Brilliant for Sight Reading!

*2026-03-30, version 3.0.2*

I learned to read music when I was younger, but then went many years without practice and forgot a lot of it. This app has been brilliant helping me re-learn to sight read, especially when I get stuck with tricky passages! My 8 year old son now also uses it as he’s just started having keyboard lessons, and he finds it easy to use.

### 5/5 — A really useful app

*2026-03-28, version 3.0.2*

Yet another great app from Jet Powered Apps.
