How to choose

If you convert units more than a few times a month, want formulas shown, and need the same tool to work on phone and laptop, UnitSwiftPro is the right choice. If you only need the occasional conversion and you're already on Google, the search box works fine. If you need a dedicated mobile app, ConvertPad is solid — but you'll be installing software and giving up desktop access.
