Tips that read the same both ways. Mirror Jar rounds your tip up so the total is a palindrome, like $45.54 or $123.21: easy to remember, and easy to check on your card statement. If the charge on your statement isn't a palindrome, you'll know at a glance that something changed. WHY PALINDROME TOTALS? It's a well-known diner's trick. When the total reads the same forwards and backwards, any change made after you sign stands out right away. Mirror Jar does the math instantly, right at the table. HOW IT WORKS • Open the app and type the bill. The keypad is ready instantly. • Palindrome totals for 15%, 20% and 25% appear as you type. Tap one to see the receipt. • Or tap "Show all tips" for 17 options from 5% to 100%, each rounded up to the next palindrome. Never down, so you never under-tip. • Every option shows the real tip percentage after rounding, so you always know exactly what you're leaving. SPLIT THE CHECK • Split the bill between 2 and 6 people. • Each person's amount is a palindrome too, so everyone can check their own statement.
