EZ Adder is a unique easy to use basic calculator (+ - x / %). It maintains an “electronic paper tape” of all your entries which you can view and easily correct any entry.

It’s great for performing any basic calculations. Ever try to add a long list of numbers and every time get a different answer? Then, you need EZ Adder because it lets you scroll through all of your entries and easily correct any mistakes.

EZ Adder has three independent calculators each with its own “electronic paper tape.” All tapes are stored locally and every time your app is backed-up, it automatically backs up all of your tapes. You can email the results of any tape as a formatted report to yourself or anyone else.

EZ Adder has a large custom keyboard for a quick and easy touch and a decimal slider to let you choose the number of digits (0-4) after the decimal point in the total.

It also has an enhanced % key for calculating percentage discount, tips, and sales tax:
- To compute the price of an item with a 25% discount, enter the price then enter -25%.
- For an additional 10% discount, enter -10%.
- To calculate the meal amount plus an 18% tip, enter the meal amount then enter +18%.
- To calculate the total including 8.25% sales tax, enter the total then enter +8.25%.
