Round & Split is a tip calculator designed for highly effective people like you. It has three features that I think you'll like:
1. The total is always a whole number.
This makes it easy to pay (especially in cash!) and process mentally.
2. Send an email reminder from within the app.
Send an email to remind your dining partner to pay you or request the share. The subject line is pre-populated with the split amount.
3. Easy to use, no fluff.
Enter the billed amount, choose from the most common tipping rates, pay the total (or copy the numbers to the receipt), and that's it.
Tipping shouldn't be a daunting chore after you have enjoyed a great meal. Round & Split is designed to make this process faster and easier. I hope this app will be useful to you!
