### 5/5 — Useful!

This is super handy, especially when your wattage and the recipe wattage are polar opposites (like the 700 and 1500 comparison they have in the photos)

### 5/5 — Love It!

*2024-04-23, version 1.1*

Remembered seeing this on Food Theory ! It worked amazing, easy to follow and my food is perfect! And this worked with my air-fryer too which is nice to know :)

### 5/5 — Perfect!

### 5/5 — Clean, simple, intuitive

*2018-03-28*

Tried a few of these and this is the best so far. Well done.

### 5/5 — Easy To Use

*2017-01-22*

As usual when I am looking for an app I download all of the available ones and compare them for functionality and ease of use.
This one was by far the easiest to use and after the developer (who was pleasantly responsive) fixed a display bug I have settled on this one for myself and my wife.
