What's New in Calzy

4.0

September 14, 2026

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.

Scam - account theft

Right after I downloaded this my Apple account started getting login attempts from Punjab and Istanbul.

Do not download this - the developers are scammers.

Reporting them to Apple

最初から入ってる電卓で良くない？

よく考えたらiPhoneに最初から入ってる電卓で十分だった。

Good but buggy

If you happen to hit the “Slide up” by mistake you can’t bring your calculator back up. You just have to close the app and re-launch it. And it happens a lot.

Sounds?

I don’t hear any sounds, but the haptic feedback works.
