Best Calculator App

If you use a TI-84 or TI-83 regularly, you are going to love this app! I'm a high school math teacher. It is really wonderful to have an app that works like the calculator that I regularly use! I like it so much I promoted it on my math website!

Best Calc for iOS

I used a TI-83 in college (engineering) back in the 90’s and this is the perfect digital calculator I’ve found. Free updates with it are great. I don’t use anything else and haven’t for years.
