Not in Control Center, Must be Oriented

Outstanding calculator with two important problems. It does not appear in the Control Center of the iPad. With the iPhone, you can swipe up and use the calculator immediately. With the iPad, you have to find the app and open it.

If all you want to do is multiply 8 hours of work per day times 14 days in two weeks of work, but you are viewing your iPad horizontally (like a TV screen), you get a horrifyingly complex calculator screen that is confusing to use. You then have to reorient your iPad to portrait to use the simple calculator, but then when you close it, whatever you were viewing appears different in portrait view. (keyboard, mail, photos, etc.)

Five stars when it is finally included in the Control Center and when there is finally a choice to use either calculator in either orientation.

Overall great

I really like this app. If you are one of those people who uses a Calculator a lot on their phone or other electronic device, then this app is perfect for you! I always seem to get very bored of the calculator screen, but with this app you can change it whenever you want! At first I thought you have to buy each theme individually, but actually all you have to do is watch an add, and you can get any theme you want! I really recommend that you get this app. It's fun, and it's free!🤗

Another rip off. Stay away

Apps like this and Angry Birds are a large reason why I no longer waste money on apps or in app purchases anymore. After spending my money for the ad-free version with skins, I am now no longer able to restore my in-app purchase. Clicking "restore in-app purchases" does absolutely nothing. I can no longer access the skins I previously paid for. So like angry birds (which I once paid to be "ad-free"), I have to accept this nonsense from another developer. The good old days of developers with integrity not ripping you off are over. It's all about the shameless cash grabs now and this app is another guilty culprit. Stay away from this garbage.
