InstaTip: Smart Tip Calculator

Tipping is hard. 
It's just so annoying to do the math for the tip amount and write down the accurate total. When a check/bill goes to a party of people, splitting the check/bill just makes the math even harder.

InstaTip is a smart tip calculator and check/bill splitter for daily usage. This app is thoughtfully crafted to provide an intuitive UI to calculate the tip, round the total, and split with multiple people.

Core Features:
• Bill/Check text recognition for automatic tip calculation.
• Tip based on the tax-excluded amount (before tax), to avoid the unfair tip suggestions shown on the bill/check.
• An intuitive bill/check view. Just input what you see on the real bill/check and get the tip and total automatically.
• Customize the tax rates.
• Calculate the tip by 3 customizable tip rates or input tip rate directly.
• Tip rounding:
• Round total or tip up or down.
• Palindrome round. For example, $76.23 will be rounded to $76.67.
• Tautonym round. For example, $76.23 will be rounded to $76.76.
• Tip splitting, show tip per person and total per person.
• Display current date time and address to help to recall the payment.

Tips:
By using "Palindrome total" or "Tautonym total", you could easily validate your transaction on the credit card statement later.
