Dictate your math equation and get an instant answer. Now I can calculate long sequences without taking my eyes off the data. The app will even speak the answer. Ravi, kudos.

A very pleasant surprise!

After trying countless other calculators that claimed to be hands-free calculators, I stumbled upon Simple Voice Calculator. I had about given up on finding a calculator that I could use hands-free and was very pleasantly surprised to find this one works very well. It is, indeed, simple and accurate. Thank you for a great little app!

I love this app!!

This works very well once you get the hang of it. You have to learn how to speak the numbers and you need to watch to be sure the app recorded it. Very simple and huge saver once I got used to it.

Just what I was looking for...

Now I can add a very long sequence of numbers and get immediate results after each additional number. I'm able to do this without taking my eyes off the data. This saves me so much time. And certainly helps eliminate errors. Thank you.

Surprisingly useful!
