But in OSX Big Sur, I'm getting black text on a charcoal background, and it makes the entire interface illegible. ### 1/5 — Wouldn't open after download *2020-10-13* I downloadedthis app and it wouldn't launch. That makes it pretty much useless. ### 2/5 — Can’t see the result?? *2020-07-28, version 1.2.3* This app seems like a great idea. After install it is in the Bar but on using it The result is unreadable because the numbers are blacked out? iMac with 10.13. Please fix ## Most critical reviews (10 lowest-rated) ### 1/5 — Spyware? *2025-10-05* Does’nt even open….I really think this is Spyware…I can’t delete it even!!! Very scary!! ### 1/5 — Worked for a while *2024-05-05* But now it does nothing when I click on the icon. Although it says the app is open when I try to delete it. Nothing to be seen and can't find it. ### 1/5 — totally useless *2024-04-15, version 1.3.1* Never works ### 1/5 — Installed it and did nothing *2023-11-15* Installed on MBP M1 Sonoma 14.1 and the app did nothing. It did not appear on the top bar and it did not appear as an app window. Had to stop the process so I could delete it. ### 1/5 — Can't enter fractions *2023-04-11, version 1.3.1* When converting inches to milimeters, the app does not accept common fractions of an inch. eg: ⅜ inch cannot be entered. ### 1/5 — wacky *2023-02-19* conversion is wrong for teaspoons to cup. There are exactly 48 teaspoons in a cup, this app says there are 48.6922 teaspoons in a cup. How do you get stuff like that wrong? ### 1/5 — Black Fonts On Background, You Can't change It. *2021-10-29* You must have to some special power in your eyes to use this app because this app has dark black fonts on dark black background and funniest thing is that you cannot even change it. Pros: After installing this app, atleast you can laugh at yourself till you uninstall it back. Good Luck ;:-) ### 1/5 — doesn't work *2021-09-04* Runs but won't allow typing on Mojave. Overly complicated 3 pull down menu system for conversion... select type of unit, then from then to. So, assuming it does actually run on other versions of OS X, If you're looking for a simpler solution than typing 'XXcm to in' or '100cad to usd' into Google, this isn't it. ### 1/5 — wheres the currencies? *2021-04-15, version 1.3* Got it to convert currency. It dones only one! USD to USD! Whats the point? Deledted the app. No use. Cant say it converts currency if there is only one currency you can choose. ### 1/5 — Cannot see anything *2020-11-30* The app is in black and I cannot see anything that I type. If there's any way to change the look of the app, let me know, please. ## Most praised reviews (10 highest-rated) ### 5/5 — Simplicity of use *2023-03-10* The App does everything I need and is very easu tp use. Other apps are ovrelly complicated. ### 5/5 — Fantastic little app *2022-09-04* Love that its so easy to use. Thank you so much for making it and sharing. ### 5/5 — Works well *2022-04-06* I was looking for a widget that worked like one I had used when Mac supported Dashboard, and this is it! Has everything I need, and is easy to use. ### 5/5 — works great no problem with black *2022-03-20* Change the apperance to auto or light in General in system preferences and your problem is fixed ### 5/5 — Simple Interface *2021-09-11, version 1.3* An easy to use and non-invasive interface for conversions. ### 5/5 — Simple and works *2021-05-26* Just what I wanted no B.* Great work ### 5/5 — PERFECT *2020-11-17, version 1.3* It's Perfect, just like the version that I had on my old iMac(2007).. Appologies for my last comment. I was quite wrong. Just didn't spot the icon up in the menu bar.... (I obviously need new glasses!!!) Kind regards. ### 4/5 — good even though not all units are present *2022-04-20* worked for a while but suddenly stopped launching but reinstalled and now working again but i used appcleaner to uninstall all files before reinstalling so your milage may vary. ### 3/5 — No negative numbers *2022-01-07* Cannot type negative numbers into the app, which for temperature conversion is a problem. Otherwise it has basic functionality for making quick conversions straight form the menu bar which I like. I hope the developer keeps working out the bugs. **Developer response:** Hi Timo, Very sorry about that, thank you for letting me know. This has now been fixed in version 1.3.1. Kind regards, David ### 2/5 — Weird values *2025-05-14* Basically works but what are Cubic Centimetres? ... ever hear of millilitres or centilitres...? It's like the one thing you're supposed to do, you didn't understand. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
