I use mainly for Rugby League transfers where weights and height are in cm and kilos. Being older, I use Imperial and find the transfer so easy and immediate. Highly recommend.

Best!!!

### 4/5 — Works great for converting sizes

*2021-08-26, version 1.0*

If you are like me and arent great in converting sizes or metric-this works great. I couldn’t give it 5 stars because I couldn’t get the app to keep inches to feet vs changing it every time to metrics.

### 5/5 — Doddle app

*2021-02-25, version 1.0*

Such an amazingly easy app covers everything you need for day to day.
