TipJar is an app that automatically tracks how much you tip.
HOW IT WORKS: For any venue that has paper receipts with a write in tip, there are two credit card interactions that take place. The first is a pending charge without a tip. The second is an actual charge with a tip. We take the two charges and calculate the difference.
SECURITY: We use Plaid for all of the sensitive financial stuff. We never touch your sensitive data.
