### 5/5 — Thank you

*2025-04-28*

Uncomplicated, boasting an impeccable design, and remarkably user-friendly.

### 5/5 — Clean, simple, effective

*2024-03-22*

This app should be ranked higher! The design is the closest to an Apple iOS app than many of the others with chunky buttons and a bunch of clashing colors. The UI is simple and easy to understand. And there’s even an option to turn off ads for children! I would be happy to pay a small fee for this app to support development. As of now the only missing feature is cooking measures.

### 4/5 — Good but needs one more thing..

*2024-02-05*

All this needs is the ability to configure the precision of the result (e.g specify 4 significant figures)
