★☆☆☆☆ Duh Monkeh · Jul 28, 2026

It's a calculator. Why tf should people have to pay 68 a month just to do calculations if I wanted to I could've just used Google for this shi

★☆☆☆☆ Edward R · Jul 21, 2026

Can't use it due to the ads, and it wants £14.99 A WEEK to remove the ads. Who's paying £780 a year to use a calculator app 😂

★☆☆☆☆ Antoine Gandou · Jul 26, 2026

Didn't even bother, immediately hit me with a subscription and uninstalled. It's a calculator, for god's sake, I'm not paying a monthly fee to unlock the mere concept of math
