Almost Perfect

This is dang near perfect: works with a keyboard! Works in Split Screen! No ads! Data not linked to your identity! History tape, keyboard shortcuts, shareable history… seriously, almost everything I want. There’s just one thing that makes it impossible for me to use: It doesn’t work in Slide Over. You can use the calculator itself in Slide Over, or you can view and share the history, but you can’t do both. Once you view the history, there’s no way to get back to the calculator in Slide Over, you must change to Split Screen, or close and re-open the app, that kind of thing. If this app ever gets Slide Over fixed, I will certainly download it again and definitely update my review. Until then, might as well delete it and keep using the calculator on my iPhone while working on the iPad. For what I’m looking for, this app is unusable.

UPDATE: This app is working perfectly now! I love it! The developer fixed it in the latest update, and I can confirm that now it works in Slide Over. It went from being unusable to being exactly what I want. Seriously, if I had the talent to be able to develop apps, this is what I would make—it checks all the boxes for me. I don’t need scientific functions or anything fancy, but I do need a history tape. I really like the tape in this app, because each equation has it’s own “bubble” in the history tape window, which makes recognizing each one simple. I kind of can’t wait for my friends to ask me if I use a calculator app on my iPad, so I can recommend Calculi to them and tell them about all the reasons they’re going to love it, too.

It calculates, but the history is buggy

When I open the app and make a calculation, it does not appear in the history. If I go back to the home screen and then return to the app, my previous calculation now shows. When I do the next calculation, it replaces the info in the top tile instead of adding a tile. On the next calculation, things start working as they should. This is the pattern every time I clear the history.

I would give this app 5 stars if not for the buggy history. Without that feature it is a decent calculator, but then it is just a calculator. Please fix it for a great app!
