However, why do I have into Google for app support and web site though? :( ### 3/5 — Cumbersome *2022-12-10, version 1.1.25* This is very limited in the types of conversions it handles. The four shown on the logo aren’t representations of the type, they are the types. Not only that but each type converts into a tiny set of units possible. As if to make up from what’s missing from the tools the UI feels like it’s overcompensating by spreading out a ridiculous amount. I don’t think this can justify the space on my devices- it’s just too limiting with a cumbersome UI. ### 3/5 — Review *2021-12-29, version 1.1.25* It’s OK ### 5/5 — Great app *2013-07-11, version 1.1.1* Great app, simple, fast, easy . ### 5/5 — Easy to see results *2013-05-02, version 1.1.1* Nice and Easy ### 5/5 — Useful app *2013-04-13, version 1.1.0* Simple and easy to use ### 5/5 — Great app *2013-03-26, version 1.0.0* Very useful!!! ## Most critical reviews (10 lowest-rated) ### 1/5 — Pointless… *2023-06-25, version 2.0.0* A previous review said this app couldn’t be used because anything typed in did not appear. The developer replied that the problem had been fixed with the latest version - no it hasn’t! I’ve tried at least 5 times to carry out several different conversions and nothing appears when trying to enter values. I’m glad this app was free because if I’d paid for it I would be requesting a refund from Apple. One word sums up this app(?) - pointless! (and yes I’m trying to use the latest version that says it was updated 2 days ago. I installed it on my iPhone 14 Pro Max yesterday June 24th) ### 1/5 — Still white *2023-06-25, version 2.0.0* Font still white 2 years later ### 1/5 — White over white *2023-06-24, version 2.0.0* Text shows up as white text on white background. Impossible to read unless u highlight the text. ### 1/5 — Bad *2021-01-20, version 1.1.24* Very bad ### 1/5 — Can’t see output *2020-12-20, version 1.1.24* Text comes up white, so can’t read inputs or outputs in converter tool. Tried investing colours, but same problem. Useless. ### 2/5 — No PSI *2024-05-06, version 2.0.3* I downloaded the app to convert psi to bar but didn’t find it! ### 2/5 — Not enough types or categories *2024-02-07, version 2.0.3* I tried to convert 104 oz to quarts, due to the measuring containers I have, but you don’t have quarts to choose. You don’t even have gallons to choose for volume. I have found this a huge error in your app. ### 2/5 — Hear Me Out *2023-07-21, version 2.0.1* I’m not a math genius, so I tried out this App. Any third Grader knows 36 inches equals 1.0 yards (not 0.99999999492 yards) and 36 inches equals 3.0 feet, not 2.99999998476 feet. Developer needs to fix ‘Precision’ and not ‘Rounding’. BTW I didn’t run tests on any other units, I only gave Imperial units a quick test. ### 2/5 — 3 issues! *2023-06-22* Can't see with dark theme! No numbers are shown in my iPhone 12 mini's iOS v16.5.1. Also, no release notes for v2? Why do I have into Google for app support? :( **Developer response:** Thank you for your feedback! We are checking the theme issue and will release a fix shortly. You can contact us directly at support@vistechprojects.com ### 2/5 — Easy to use but incomplete *2013-05-02, version 1.1.0* No miles, kms, grams, oz, liquid conversions etc ## Most praised reviews (10 highest-rated) ### 5/5 — 👍 *2025-06-19, version 2.0.3* Лучшее, бесплатное приложение! ### 5/5 — Super! *2024-03-05* The best program! ### 5/5 — Great App *2023-06-21, version 1.1.26* Does what it says it will with no problems. Completely intuitive with no weird issues, which is rare. ### 5/5 — Fast and easy *2022-10-12, version 1.1.25* This does the job every time, thanks! ### 5/5 — Converter app *2022-07-26, version 1.1.25* We use it to convert daNm to foot pounds for torquing bolts on Italian made Cormach Cranes, very helpful, thanks! ### 5/5 — Quick Handy Converter App *2021-04-08, version 1.1.25* iPad and iPhone both running iOS 14.4 - This app now works great! In the past I left a negative review as I could not use this app with dark mode on my devices as the input data was the same color as the background. The issue is now fully resolved and this app works great. Developer is very responsive and has fully resolved the issue. My thanks to the developer for a simple to use app that works great. Job well done! ### 5/5 — This app never fails me! *2020-02-09, version 1.1.21* I live in China so I am converting numbers all day. This app saves me. Always fast and accurate. What more do you need? Thanks guys! ### 5/5 — Very very good!👍🏽 *2018-05-11, version 1.1.18* Great 😎 ### 5/5 — Nice app *2013-10-17, version 1.1.2* Easy to use, thanks for fixing negative temp values ### 5/5 — Minus temperature *2013-07-26* Guys, thanx for this awesome useful app, really helps a lot. One thing,though- even after the recent temperature patch i STILL do not get how you can put minus in front of the temperature number.... --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
