“Go-To” For everything!

I am a self-taught Astrophysicist, Astronomer, and Rocket engineer (simulated).
 I searched a long time, through a ton of different software to make unit conversions or specific mathematic formulas, easier. I then found 12 in 1 Calculator.
Very intuitive design, and has such an incredibly versatile library.
 I really enjoy reading my biorhythm statistics!

I recommend this if you’re anything like me, I love chemistry, geometry, math, mechanical engineering, (coding soon). I do it all, and 12 in 1 has it all!

Bummed

I have used this calculator for years. Very disappointed that when I finally needed the mortgage calculator that I can’t print or share the amortization table. Reason for dropping my review.

Great calculator other than that.
