### 5/5 — Excellent App has an error

*2026-05-28, version 7.1*

There is an error in Mass conversion. English Ton is listed as 2000 pounds, this is wrong. It is 2,240 pounds. U.S. Ton is not listed, this measure is 2,000 pounds. Please include both U.S. and British Imperial Tons correctly in Mass conversion.

### 4/5 — Works great, no annoying ads! Thanks

*2022-05-17, version 7.1*

I’ve had this on my iPhone for a few years. It’s a great tool. My only complaint would be a couple times I’ve found I wanted a certain unit of measurement that isn’t on the app. One example is “Minutes per Mile”. Runners use it rather than mph. Otherwise it has worked flawlessly. Thanks

### 1/5 — Does NOT work!

*2022-03-12, version 7.1*

Just shows errors in the conversion display. Don’t bother downloading this garbage.

### 5/5 — NO ADS & Simply the best

*2021-10-24, version 7.1*

### 5/5 — Perfect app!

*2021-07-30, version 7.1*

It does it's job really well! I like that you can add your own units. Thank you for making it free!
