Latest reviews, United States App Store.
I really like this calculator! It’s simple, fast, and easy to use. The calculation history is very helpful because I can review previous calculations without starting over. The design is clean and convenient. I highly recommend it!
It helps me do hard questions secretly😈
No es igual a otras, es diferente y mas facil de usar
I just have one issue. In the unit converter for time there is no option for month… that has to be an over sight please fix
Suddenly, you cannot delete your calculator history line by line the way you’ve always been without the app crashing. Approximately every fourth or fifth deletion, the app glitches & closes completely out and when it opens back up, all of the previous data that you deleted is actually restored. When you restart the process, the same thing happens again and again. So, annoying! FYI, when the app is functioning properly, you can erase the calculator history line by line by long pressing the trash can symbol. Then, long press the calculated line and selecting the delete option. ~iPhone 14 Pro Max, iOS 27.0.1 (FYI, for the developers)
History is accidentally erased and cannot be recovered. Was told to pay extra for history paid for extra history again accidentally erased cannot recover. Tried to contact for months no response. No way to get in touch with these people. I go through the app no response. Looking for a new calculator so I could run my business through my phone through my app through a calculator. I have not found any success , extremely disappointed, Have not been able to find any solution on my own or through the company
