Didn't give me a refund because I accidentally choose the wrong subscription the app was great the service and refund system was bad

★☆☆☆☆ Destin Mattias · Jun 15, 2026

Who in their right mind will pay $15 PER WEEK for a basic calculator app? These "developers" are just hoping people will forget to cancel the trial and only notice the payment when it is too late. Pure money-grab!

★☆☆☆☆ Joakim Enger · May 28, 2026

Worst calculator oat. At least have something more scientific; or at least no ads if it's going to be this useless.

★☆☆☆☆ Dave M · Jun 2, 2026

0 stars. Do not download this... why would folk want a calculator app for their phone when most come with one already installed AND why would folk then say' oh that's a fantastic offer, I'll sign up and pay for it' doesn't make any sense at all. Pointless
