Best unit convert app

I looked through a lot of unit convert apps. This is the best by far. I’ve been using this for about a decade. Nothing better out there.

Brilliant..... until iOS 14.2

This App was brilliant, until I updated to iOS 14.2, now it won’t open. I am lost without it.

Perfect

Excellent app; thorough and very easy to use. Love the way clicking the value initially imputes a 1. More helpful than one would at first realize.

Excellent

The best conversion app by far.
