It does have a good amount of conversions, but if it had a money converter added it would be perfect. If you want a converter app and don’t need a money converter, I would recommend that you get this. It’s great that you only pay once for the app, and it’s not a cash greedy monthly or yearly subscription! ### 2/5 — Missing Important Length Until *2026-01-27* Nautical Miles is the unit used in shipping and aviation worldwide. The converter is incomplete without it. ### 2/5 — Missing Something Important *2025-12-17, version 8.1* There are no Nautical Miles in Length category. ### 5/5 — Very useful *2024-06-18* Great app, use it a lot! ### 5/5 — Excellent App *2024-04-16* Very versatile. Easy to use. ### 5/5 — Best in-Class *2024-02-18* Best in-Class Most various unit categories Correct Calculation between units No Drop Down menu Easy lookups ### 5/5 — Portrait Mode, Please *2023-11-22, version 6.8* Portrait Mode, Please! With Kindest Regards-BR ### 4/5 — My Fav Unit Converter *2023-09-08* Super easy with loads of relevant info. It’s my go to app for anything I need converted! ### 5/5 — Good choice *2023-07-25* I have used this converter for many years, mostly to inform me of hight and width of my plants at their mature growth. It works flawlessly! Love it! ### 5/5 — Great App *2023-07-09* Use it all the time in process controls engineering! ### 2/5 — Not userfriendly *2023-01-31* It might be a good software but I’m lost with the interface 😵‍💫 ### 5/5 — Great Unit Converter! *2023-01-16, version 6.2* Works great and converts lots of different units. ### 3/5 — Works but not intuitive *2023-01-04, version 6.2* Only works in horizontal mode. Not very intuitive to use. ### 5/5 — Use this all the time *2022-12-13* Super handy! Love having this app around ### 5/5 — Unit converter *2022-11-20* Very handy app! ### 5/5 — Extremely Useful *2022-09-28* It has never failed me when I want to convert measurements that are unfamiliar. Today I used it to convert millibars to inches of mercury in order to understand a weather report. It is perfect for those questions like “How many gallons of water does my back yard get when there’s 2” of rain?” It is one of the most valuable applications on my phone. ### 4/5 — Very useful *2022-09-10* A little bit clunky in the interface especially if you don’t use it very often, but overall I like it ### 5/5 — Excellent app *2022-09-03, version 5.9* It converts many dimensions , volumes, etc. quickly and accurately ### 5/5 — Millwright *2022-06-28* Super Handy! ## Most critical reviews (10 lowest-rated) ### 1/5 — Waste of money *2024-05-27* Cheap ($0.99) but still a waste. Deleted it within 30 seconds. Very limited unit categories. Needed it for Torque. Nope. ### 1/5 — After the update 👎🏻 *2018-07-31, version 3.3* I can’t open the app after the last update, i hope you fix it. ### 1/5 — Inaccurate. *2018-02-16* The conversions for fuel mileage are not accurate. 10L/100km should be about 28.xx mi/gal UK. The conversions to US are even farther out ....400+ mi/gal ....for the same 10L/100km. ### 1/5 — ok, but missing important units *2018-02-16, version 3.2* for example electron volts for energy and no magnetic field at all. instead, many useless multipliers, like milli, micro, kilo, Mega etc - those are standard and only take space and create long scrolling. ### 1/5 — Fehler bei Temperatur in C *2017-10-22* Fehler bei der Temperatur in C Kein Support erreichbar. Deshalb ein Stern ### 1/5 — TB *2017-10-05* Torque conversion is not on latest update. Why? In fact a whole lot of conversions are now missing!! Please put them back. This was a fantastically useful app, now not so useful ### 1/5 — Nice to know I wasted my money *2017-06-26, version 2.3* On an unsupported app. The app cannot even convert Kg to Lbs. It would be fine if they company kept at it. But, nope. ### 1/5 — Disappointed *2013-11-04, version 2.3* I thought I could enter a specific length in inches and it would automatically convert to centimeters. Does not work that way at all. Very disappointed. ### 1/5 — Not so convenient *2013-08-21* It doesn't have the option of converting any 2 particular units. It's very disappointing . ### 1/5 — terrible ui *2013-07-22, version 2.3* seriously. ## Most praised reviews (10 highest-rated) ### 5/5 — Awesome *2026-05-10* Super convenient ### 5/5 — Fantastic *2025-07-26* It’s free ### 5/5 — Handy *2025-07-04* Great ### 5/5 — Unit converter *2025-03-22* 10 ### 5/5 — Works great! *2025-01-20* It does what it should. Love all the options available for conversion. ### 5/5 — Very useful at times *2025-01-16* I don’t use it that often. But it does come in handy. ### 5/5 — Love it *2024-12-15* It’s simple to use and has every converter I need ### 5/5 — Must Have Utility App *2024-11-11* Being handy and useful, it’s one app that’s been on every iPhone I’ve had. ### 5/5 — Great App *2024-09-07* This App gives me the unit conversions for anything I have needed so far. ### 5/5 — The Best *2024-09-06, version 7.3* This is the best conversion app I have found. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
