Tipulator by Sophia Teutschler
Do you feel hesitant or uncertain when it's time to leave a tip? Tipulator to the rescue! This great app for the iPhone enables you to calculate percentages based on the total bill and calculates divisions in case you want to split the bill. This app really comes in handy! Tipulator received its last update in September 2013 and is not capable with the latest operating systems.
With the development of Siri and automated services like Apple Shortcuts app, Tipulator or apps like this are no longer necessary. A simple Siri command can get you the same results.
