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 ### 4/5 — good app. tons need updating *2021-06-13, version 7.1* it lists british ton as 2000lbs but that’s actually the short ton. british ton is 2240lbs. ### 5/5 — Doesn’t open anymore *2020-12-07, version 7.1* I love this app & use it all the time. Very useful, except I can’t seem to open it anymore. ### 5/5 — No Longer working? *2020-11-24, version 7.1* Been the best app! Hopefully it’s just a glitch ### 5/5 — Works great *2020-11-03, version 7.1* Perfect for on the fly reference, always using at work ### 5/5 — Amazing app *2020-10-17, version 7.1* This is completely ad free and is really easy to use with all conversions you could need, thankyou for this app! ### 4/5 — Great but... *2020-08-09, version 7.1* Love the no ads aspect but have found some inaccuracies in some conversions. ### 4/5 — Very useful..could upgrade to include nutrition? *2020-07-07, version 7.1* Love this app, always use it and so easy. Only small suggestion is that I use another app to convert kilojoules to calories. Maybe this range of conversions could be included too as a “Nutrition” category or something :) ### 5/5 — Yeah! *2020-01-27, version 7.1* Very neat, small but quite powerful app. Recommended. ### 5/5 — The best converter out there *2020-01-12, version 7.1* The best converter out there ## Most critical reviews (10 lowest-rated) ### 1/5 — Does NOT work! *2022-03-12, version 7.1* Just shows errors in the conversion display. Don’t bother downloading this garbage. ### 1/5 — Not working at all any more *2021-02-07, version 7.1* This was a great little app; worked perfectly until now. Please update it! ### 1/5 — Was Handy *2021-01-18, version 7.1* Tried to open tonight (18th Jan 2021) and it immediately closes.

Maintenant l'apps plante dès le démarrage! ### 1/5 — No updating in years *2020-12-14, version 7.1* It was working now all of a sudden not working keeps crashing because it has had no update in years doesn’t work with the latest IOS VERSION ### 1/5 — stopped working on iPad Pro *2020-12-08, version 7.1* needs serious update ### 1/5 — Why? *2020-12-01, version 7.1* Doesn’t work on Iphone XS ### 1/5 — Developed Problem *2020-11-29, version 7.1* No longer work with iPhone XS Max ### 1/5 — Hey *2020-10-13, version 7.1* Where’s the torque!? ### 1/5 — Some Shortcomings *2020-05-06, version 7.1* The screen resolution and interface is excellent but, I have to agree with “The Engineer” because there is no acknowledgement of USA Pound and Ton differences compared to UK. I lost confidence after realising this. ## Most praised reviews (10 highest-rated) ### 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. ### 5/5 — Very useful *2025-09-17, version 7.1* An underrated piece of software.
