Best calculator so far, however the split view feature is bugged. It appears on the other apps space as well.
In regard to the developers:
The review I give represents my experience using your application. The amount of stars has nothing to do with the app being free. If I find an app useful, however it is applying an ad based charging system, I’m willing to pay money for them to disappear. There is no reason to be butthurt about my opinion, I simply thought it might be bugging that’s why I wrote my review in the first place. If you pointed out that I was wrong, you could at least try it in a well mannered way - like you give a damn about your users, not making a fuss and attacking them, claiming there are other apps in the app store that fits me. Thank you, I’m mature enough to make my own choices.

Has it not been for your reply, I would’ve changed my rating.

🤔 The split view behavior on iPad works exactly as it’s intended to do - it occupies the full width of the device just like any other custom keyboard.

This standard keyboard behavior is one of the key features of Kalkyl and differs from almost every other calculator - and that’s because it’s much harder to implement. 🤓

If it’s worth pulling 2⭐️ off a review of a free (and ad-free) app for this, then there’s probably other calculators that fit your needs better. 💔
