Doesn’t remember its window position, buries conversion options several clicks deep, and frequently becomes completely unresponsive. For clearing values, it only recognizes its own C button or the C key on the keyboard, not the Clear key on a numeric keypad. I hate using it, and will revert to using UnitsPlus on my iPhone instead. ### 2/5 — works ok, bit weird. *2024-02-01, version 4.2* works ok, bit weird. Could I have favourits at the top of the list. I don't care about the rest of it for quick access. Customise the side-bar. Also the clear button on my satechi keyboard does not clear the values. Nore does the Enter key do anything!!!! Extremly anoying! ### 2/5 — Sort of ok, but could be better *2023-12-09, version 4.2* I can select the units to convert from and to only at the beginning before adding the amount. Once this is set, it's not possible to add other units, despite the "Add Units" button suggesting otherwise. Seems a bit counterintuitive. ### 4/5 — Good app but missing basic conversion *2023-04-07, version 4.2* Nice looking app and easy to use. My only issue is I can’t easily convert from weight to ‘Stone and Pounds’. I need to do this regularly and having to convert the pounds from a decimal number each time is frustrating. Overall would recommend. ### 4/5 — Crashing *2018-03-06, version 3.0* Hi Jamie, the app was much simple before now it’s not usable and is crashing please can you take a look at it ### 3/5 — Units are messed up *2015-03-21, version 2.0* The units are flipped. 1 elephant is 0.001 pounds and 1 pound is about 10000 elephants. PLEASE FIX THIS. It's a little bit annoying. But overall amazing app. It does everything I need it to and has every unit imaginable and then some. ### 4/5 — Moles *2014-04-03, version 1.2* You guys should add grams to moles and liters to moles basically just moles ### 2/5 — Not that great *2014-03-26, version 1.2* You can't enter negative values or even zero for that matter. An "unable to convert" message comes up. This is a problem when converting temperatures. Looks like there are some kinks to work out. ### 1/5 — Huh? *2014-03-21, version 1.1* A blue whale is equal to .001 pound??? One pound is equal to 1700 hippos? Wouldn't trust this app to convert Monopoly money. ### 4/5 — Not bad! *2014-03-21, version 1.1* Just three requests... 1. Make the icon a different color. Orange is a bit obnoxious. 2. Allow color changes within the app. 3. Select favorites for currency/eliminate others I don't need. Otherwise, I like it. ## Most critical reviews (10 lowest-rated) ### 1/5 — Very limited for a unit converter *2025-01-26, version 4.2* You can only put together 3 units to convert at the same time. This is not a problem for temperature for example, where you normally go from f to c and vice-versa. But for some others like weight and length that you have lot of metric and imperial options it becomes very limited. I need an app the helps me get more productive not the opposite. ### 1/5 — worthless *2024-10-03, version 4.2* worthless ### 1/5 — Crashes *2022-11-09, version 4.2* When I am trying to add the 'Weight' catyegory of conversions the whole app crashes and closes. What's the point in paying for a converter that is incapable of converting simple units? ### 1/5 — Quits Unexpectedly *2022-09-21, version 4.2* Tried to select the Currency conversion from the list three time and all three times it crashed. Will stick to my phone app which has a userfriendly and cleaner interface. ### 1/5 — Forget the upgrade *2022-06-04, version 4.2* The app downloaded fine 1st time., I've tried tgo upgrade and it crashes as soon as you select Upgrade. Look elsewhere folks! ### 1/5 — Keeps Crashing *2022-04-01, version 4.2* Using 2015 MBP. Keeps Crashing. ### 1/5 — The worst for Apple watch *2020-12-14, version 4.0* It was great before but now with the new version you don't have the option to tap the numbers on the Apple watch. Good luck trying to convert 400F to Celsius. I'm deleting it from my devices. ### 1/5 — Not working *2018-04-05, version 3.1* This is the second update that is bug. My app does not open now ### 1/5 — Not great update *2018-03-24, version 3.0* This new update doesn’t work as well as the previous version. It’s aggravating to have to scroll through every single unit type when all you want is to look up currencies. It is generally clunky & letters/numbers are difficult to read (not everyone has perfect vision) regardless of background colour. When trying to view currency, I could choose the currency but the app wouldn’t/couldn’t let me pick one to convert to. Kinda pointless ### 1/5 — New version just keeps crashing *2018-03-11, version 3.0* Have been using this seamlessly for a year or so; last time was about 2 was ago. Went to open today & it’s not working at all. Please look into this ## Most praised reviews (10 highest-rated) ### 5/5 — Very nice *2024-06-24* Clear, live conversions, favorites, and smooth screen/keyboard integration. All I would request to add is a menubar item -- ideally to use it, but if simply to launch it would be nice. ### 5/5 — Exactly what it says on the tin! *2020-11-02, version 4.0* Fantastic app, clear and concise. Couldn’t ask for more! ### 5/5 — The best converter ever *2020-11-01, version 4.0* There can't be a better converter than this! I'm a person who converts units day in and out because of my studies. I have used at least dozen unit converters but wasn't happy with their boring and confusing functionality. Plus it takes so much time to learn how to use. After installed Unity: The Best Unit Converter I have stopped looking for other similar apps. It's just the best. Just like the app their support team is fantastic too. They are always available to help you. I seriously recommend this app to everyone out there looking for a converter powerful. ### 5/5 — Perfect! *2014-08-15, version 1.4* This apps do the job very well and we can use it online! Good job. ### 5/5 — Excellent *2014-05-03, version 1.4* and useful. ### 5/5 — It's in the name... *2014-05-03, version 1.4* I've had an iPhone since they released and I've used numerous conversation app on my iPhones over the years. Out of all of them this app is by far the best! The union of form, function and aesthetic appeal makes it's name UNITY completely representative of the application. This is a must have on you iPhone! ### 5/5 — Unity is good. *2014-05-02* Great little tool easy as, I use it often. ### 5/5 — Great app *2014-04-11, version 1.3* Good app. Fun to play around with. ### 5/5 — Request *2014-03-27, version 1.2* please add afghanistan curancy (AFN) afghani ### 5/5 — How many Hippos ? *2014-03-20, version 1.1* This is a fun and practical App, check it out, we like it a lot :-) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
