What is Round My Tip? The idea is very simple: Suppose you're in a restaurant. You're getting your bill. It's some weird prickly number, like $37.84. You want to leave something nice and round like $40. 00, but now you have to: 1. Calculate how much the tip is. 2. Make sure the tip is not too big or too small. 3. Stress out about it like you have no better things to do. That's where Round My Tip comes to rescue. It is extremely easy to use - just type in your bill numbers and that's all you need to do. It'll make all the calculation for you, and a tip percentage hint will make sure you leave the right amount. Could it be easier than that? (The answer is: no, it couldn't) Enjoy your round numbers and the life of riley.
