Very good but...

There is a glitch that whenever I use the search for advanced functions, after I type a character, the keyboard glitches and closes. This is problematic and irritating since I have to type one letter at a time and it takes longer. Another bug I found is that whenever I put the phone into portrait mode, whenever I use the timer, half of the bottom buttons seems to show; however, the other half is off screen. Other than the problems mentioned, it's pretty good. I haven't run into any other problems...yet.

Doesn't get any better than this

I just spent the last week, looking at and trying many different calculators, even paying $10 bucks for one of them and none of them are as good or are as complete as this one. The interface has a small learning curve but with it comes amazing flexibility and powerful features. I don't usually write reviews but this one is well worth it!

BEST Calculator App!

That's all I can really say. I had been through several and none of them impressed me, but once I realized how this one works I love it! You should definitely download this app. It's all you'll ever need a calculator. It's killing me that more people haven't tried it out! Forget Texas Instruments!! Lol 🙃
