I can juggle words, but I had no idea you could juggle stats (percentages in this case) in so many useful ways. The selection of calculations made by the team is fascinating and… more importantly… very useful and usable! Bravo!
I’ve used this app now for years to help me work out percentages. It’s so handy!
Couldn’t get past initial screen due to new offer 3 day trial and although I didn’t want it I could not get rid of the screen!

What a great app! Really comprehensive and really useful. Give it a go!
Had the app for years, used it all the time. Then they decide to change the format on each formula & made it so confusing I’ve had to stop using it. Why change what was working brilliantly!!!
