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 🙃

Really cool features

I don't write many reviews and I'll be short. This calculator has a ton of time saving features. The smart parentheses and smart tip calculator was an awesome idea. The new tutorial explains how to use the features well and are key to using all the features.

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!

Not working on Apple Watch

Bought the app for the Apple Watch functionality, but the app does not appear on the watch. Also it complicated to use. Missing intuitive icons and menus. There is good help available within the app but occasional users will be required to run through how to use the app often to get the most out of it. Dev team, please fix the Apple Watch functionality!
