Does not copy history result equation and result right

Update: I copy and paste my equation and result and it comes out a different number than I had calculated. Flaw in copy and paste on both choices. It has made me a little more frustrated in getting the result right. Weird functions and full screen ads. Luckily I have not purchased this app for no ads, I have removed the app and try again in the uncertain future. It was good till I had to wait a couple of more seconds for the X button to appear on the ads, fairly intrusive to calculate my tips from each individual cocktail waitress that has tipped me out. Nice clean layout but I think I'll stick with my Samsung S5 2nd phone calculator for the meantime.

Everything about this calculator is what the hard working waiters and tip receiving workers need to balance their day to day earnings quickly and correctly without pen and paper. The calculator just works and doesn't crash during use. Just need it to replace Apple's dumb calculator that just calculates and not help with historical calculations or messups. Double Thumbs up!

Please just make a one time in-app purchase fee!

I absolutely love this app, since use it for school and it is just very simple to use while also being able to use more complex equations! My only problem is the fact that I have to pay a monthly fee just to use other calculator features that are on normal calculators is just ridiculous! I understand that you guys want to make money, but do you really, like really need to make people pay a monthly fee just to be able to calculate fractions! I would be absolutely fine if it was a one time fee, but why a monthly fee!? This is one of the top most downloaded calculator apps on the App Store if not the best one, not to mention the little adds at the bottom (not distracting at all) that you make money off of adds which shows you already make quite a bit of money off of more than half a million user, yet you have to go even farther to make me pay for a monthly fee for features in every ordinary high school level calculator! I would rather have to pay 5-7 dollars once for all of the other features instead of being fed off of for multiple years to come of using this app. I would rate this app 5 stars right off the bat if it got rid of the monthly charge and maybe even replaced it with a one time fee. Please address this concern, and thank you so much for your time.

Pretty cool app!

I definitely recommend this app to people who would wish to customize their calculator in a way to make it more ✨decorative✨ and plus, you can use it like a normal calculator. Just with ads on the bottom of your screen, but they are not full screen ads that appear out of nowhere so that’s good, well, for me at least. Just to remind the people reading this, if you looked at other reviews, they might have said you need to pay to do certain stuff, which, indeed, you have to, I just got this app a week ago, so I don’t know much. When your using this app, you have to pay to be able to use the currency and fraction feature, but if your not planning to pay anything, they’ll let you try it out 3 times and then you can’t use it anymore. Overall this app is pretty good! I just took away one star cause I kinda wish they could have added more tries to use the fraction and currency feature, or in some way sort of remind us that we even HAVE a limited amount of tries, when I first used this app, I had no idea we had tries when I used the currency feature, so when it said you had to pay I was so confused. IM GONNA SAY THIS AGAIN, overall, this app is pretty good!
