Immediately close when entering data *2017-12-11* Immediately close when entering data ### 1/5 — What happened to one of my most often used apps? *2014-06-06* Crashes without opening. None of the other unit converters out there come close to yours. Like being able to see all unit choices at once. Please fix ASAP! ### 1/5 — Engineer *2014-02-18, version 1.5* Square miles to acre conversion is wrong ### 2/5 — Works OK but has a glitch *2014-12-31* The app works OK but it has a glitch. When opening the temperature converter the app crashes. I have not tried all the conversions so don't know if it happens anywhere else. I did try deleting the app, restarting my device and reinstalling the app but the problem persisted. If everything worked fine I would have given a higher rating. ### 3/5 — Crashes *2014-12-25* Rebooted iPhone 5s after it would not open (due to update). It still will not pass through the opening screen without crashing. No website support and the only current review had to be posted by seller. Do not buy until bug fix is released. ***Update- delete the app and restart your device. Reinstall the app and it will work. ### 4/5 — Good app, but… *2022-03-09* Still need to fix the long ton error. ### 4/5 — Excellent. Long ton error *2020-09-30* Love this so far. Noticed a decimal error in long ton conversion. ### 4/5 — Useful *2017-09-01, version 2.8* Great ### 4/5 — Good Technical App *2015-11-17, version 2.7* The conversions are very helpful and easy. ## Most praised reviews (10 highest-rated) ### 5/5 — Great app *2024-06-14, version 3.0* Thank you developer :) Great app to have if constantly want to convert from one unit or currency to another. ### 5/5 — Converter *2018-12-08* This is a great free app that I constantly use.
