Ratings and reviews

Hey, havent gotten to using all the super tech studd yet, but I'm glad to have a calculator that can type on most equations! Only 2 issues: 1. On the basic where is the carot/ darn exponent key??? 2. Why no...graphing calc? Regardless, take my 4.8 rating! Maybe I missed it but I checked settings and everything but cant resolve Orders xO

Don't even know where to start. It does like, everything. And it's jammed full of information. When the shtf this app alone will make a cellphone still Worth its weight in ammo. Even without an electrical grid or cellular network. Well worth the 99 cent price tag. Check out his magnetic field detector too. It's free and works 💪

This is the coolest calculator I've ever used. I only wish this technology and this calculator was available when I was taking Electronics and Engineering. The only thing I would like see added is the Darlington Pair.
