Shut up

Just wanted to tell all u people to SHUT UP this app gets the job done without any confusion at all so all u haters out there just go ahead n hate!

Have I been pranked?

Only four out of ten numbers are here, there's literally only a 0 1 4 and 7. I couldn't multiply 2x2 If I wanted too. If I could use a two, I couldnt add subtract multiply or divide. There's no signs to use. There is literally four numbers, the whole alphabet, and sin, cosin, and tan buttons. That's all you get. The only thing this is good for is spelling out words.


This app is horrible!!! Don't waste your money. It's a total waste of money and time!!! I would give it zero stars if I could 😒
