This Calculator Ap is not is that good!


First of all, I have to say I haven’t been this excited about a calculator since I unboxed my TI-30XIIS. I am so grateful for the persistent and not at all intrusive or annoying reminders to rate this AP. Finally I am taking advantage of writing this review, which will make little or no sense at all. I’m giving the AP 5 STARS because it does calculations 1000% of the time I ask it to. And 100% of the time it gets it right each time, I mean every time. I’d love to share my experiences with this calculator, I mean serious things. I mean one time I used it to calculate the mass of the moon based on gravitational force of the earth and the given distance of the moon from the earth. It turned out to be like the weight of around 300billion elephants or something like that. Which is amazing... that I could take 300 billion elephants and put them together at about 300,000 miles away and they would compress into one another and orbit earth and probably the water and elements would separate out and maybe it would form an atmosphere from the water in the elephants and we would have a new planet or moon to escape to. So thats the impact of this AP on my life, its just grrrreat!

FULL-SCREEN POP-UP ADS! Comes with free calculator.

Hallux Sinister


I can’t much tolerate ads flashing at me from the bottom of the screen, trying to distract me while I’m WORKING, let alone one that randomly pops up and takes over the whole screen. DELETING GARBAGE APP. (PS, developer, I see people mentioning this problem MONTHS AGO, so don’t write back asking me to change the review, pretending this is a “bug”. Months later, I install the app and experience the same problem another user reported (to which your customer service replied, “oh, it must be a bug, that’s not supposed to happen” months ago,) I’m not interested in excuses. Your app is gone.

I’m not happy Apple chose to make their iPad UNABLE TO RUN the stock calculator that the iPhone comes with, even though they are ALLEGEDLY running the same operating system (iOS,) but that’s no excuse for why your app tried to interrupt my work with a full-screen ad. That just created the environment where what Apple wants to pretend is a capable replacement for a REAL, actual computer, (like a PC or a Mac,) needs a third-party app, just to be able to do basic computations, and then the app makers add insult to injury with these annoying ads. No. Just no. Done here.

Does not copy history result equation and result right

DJ Dumbi

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!
