I’m not an engineer or scientist and I use it constantly. And if I was I would really appreciate it. It’s probably my most used utility. This is the first time I have ever left a second review for anything. -- VDO-Cutter, 2024-02-02 ### ***** "A must have app" Use it daily. Ideal while watching TV or reading the news. Excellent to convert metric, currency, and distance values. Use it on iPhone and iPad. -- Manigue, 2022-04-15 ### ***** "Simple and Comprehensive" This app calculates everything easily. Pick the main category, put in the number you want to convert, and the app immediately provides your answer plus the answers for every subcategory in that main category. Elegant and easy -- EB Hiker, 2020-11-12 ### ***-- "Euro default currency" Maybe I’m not seeing how to change Euro as default currency? If you want to convert USD to MD Peso, that is not an option. Very limiting otherwise very robust. -- T. Torquemada, 2019-11-07 ### ***** "Daily Work" This app is indispensable. I use it every day. Thank you. -- TheRealChacho, 2019-08-19 ### ***** "Good app" Update: I've now been using this app for a long time and it is excellent. I like the changes recently introduced in V3.0 I like this app. It's worth taking the time to customizing it to your personal needs. There's a lot to it. -- Knarffrank, 2017-11-14 ### ***** "Only the best" Converter Pro is as good as it gets. There are a huge number of categories and selections to choose from. Plus you can customize it to put the items you most frequently use on top for quick access. Without a doubt, this is a must have app. -- G. Lewis, 2017-07-03 ### ***** "Converter Pro Works" Converter Pro work easily and quickly reports requested information. I am attempting to understand Celsius temperatures in relation to my lifelong use of Fahrenheit. CP lets me switch back and forth quickly and easily. -- Runnymead, 2017-04-25 ### ***** "Great," ...simple and quick! -- nixl, 2017-01-03 ### ***** "Quick and simple!" This app quickly delivers whatever conversion I need. And it's nice to see so many categories to choose from! -- DarkshadesSr, 2016-11-23 [View all Converter and Calculator reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Converter and Calculator Discovered Keywords -
