Good and interesting app. I've installed many of your apps because your every app looks like iPhone!

EXTREMELY basic unless you pay EXTRA for pro. I already paid $0.99 for it, and all I was looking for was a "History" feature! In order to have this feature, I was required to pay MORE to upgrade to pro (surprise!). I went with a different, paid, more expensive calculator app (surprise!). If you're going to make someone pay for a calculator app when there are literally TONS of others to choose from, you should at least include the history feature in addition to no ads.

I was dissapointed that it does not have a landscape option to do scientific calculations. I purchased it in hopes of that feature and now it is essentially useless to me. Works great for simple calculations. Would've to see add copy mention that it does not do scientific calculation.

I will rate better once i have used the calculator more not when i have only just downloaded it. It's too soon to say how good it is. The only thing is does not have is a back button on it when your doing a calculation you can't delete it, you have to delete the whole thing.

It's a really good app it actually reminds you of iphone it's easy to use a few ads but it's awesome love how it actually works and it's not a scam like other apps but my main problem is when I good off and put over 20, (I think) numbers it just stops maybe it's just for me but it's a good app A+

No scientific option to follow order of operations. There's a bar trick you can do on iPhone calculators and I was hoping to use this since I have Android. However, the trick requires landscape mode and this doesn't have that option.

Its almost like the original but it doesnt have one of the most basic features: scientific mode. It was quite disapointing since i paid for it aswell but overall its good, just waiting till you add this feature
