Would you look at that! A well designed app that’s easy to use and doesn’t require access to all of my personal information. In fact, none!One of the best apps I have.
No Inverse Sin/Cos?

Not sure it’s possible, haven’t heard from the developer. But I wish there was the ability to Shift so you could get the inverse of the Sin/Cos/Tan functions like every scientific calculator. From a Scientific calculator perspective this is missing a lot of other options you would normally by shifting like this.
Calzy is ready for iOS 27.
Siri shortcuts
- Ask Siri to show a saved calculation by name and jump straight to it in Calzy.
- Add calculations straight to your saved bookmarks like Trip Budget, Groceries, or Sofa Deposit using Siri.
On-screen awareness
- See a number on screen, ask Siri to work it out in Calzy, and keep calculating from there. No copying or switching apps.
Extra Large Portrait widget
- A full calculator now lives right on your Home Screen, so you can calculate without opening Calzy.
Resizable windows
- Calzy now adapts as you resize its window, with the keypad and history adjusting to fit.
Thanks for continuing to use Calzy. I hope the iOS 27 update makes everyday calculations feel even quicker and more natural.
