T-tip calculator

I was annoyed at having to run my phone's built-in calculator multiple times in order to work out the tip amount and total when paying for a meal via credit card. Therefore, I have created this tip calculator to simplify the process.

Allow me to present to you the Thomas Tip Calculator! (T-tip, for short)

Just enter the amount of your check and the desired tip percentage, and the T-tip will display the tip amount and total for you.

In addition, the T-tip remembers your last tip percentage so that you only need to fill in the check amount.

Thank you and enjoy!
