I’ve been using this app for YEAAAARS.. it’s been so long I honestly can’t even remember how long it’s actually been. I use the calculator a fair amount of times but it’s not a super frequent occurrence and originally I wanted this calculator because the Apple calculator wouldn’t let me delete a typo without deleting the entire calculation and this also tracks calculation history. Anyway, I paid for the $2.99 ad free upgrade a few years ago and everything has been fine up until a few months ago I randomly had a $2.99 credit on my Apple account. At first I had no idea where it came from UNTIL I went to use the calculator and an annoying ad covered the entire screen. Apparently they changed things and instead of a one time $2.99 charge they want $1.49/mo to use the calculator ad free. The little ads at the bottom aren’t bad but the thing that makes it unbearable and the reason why I’m deleting the app after at the very least 5 years is the ads that popup while I’m in the middle if typing which ultimately lead to me clicking on the ad and opening up safari or app store. I don’t like the fact I’m forced to open unwanted ads to god knows what. I don’t want that on my phone. Such a shame. I might have failed math in high school but this calculator is not that important to me to have to deal click on ads because they pop up while I’m typing.
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.
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!
