Beauty in simplicity

I wouldnt want to mess with the simplicity of this app because thats what makes it so great, but it would be nice to be able to set up pay periods somehow so I can calculate my tips in a specific time period instead of it just being generalized. Also a difference between credit card tips and cash tips would help too.
This app is amazing thank you to the creator because he knows exactly what us tip earners out there were looking for. <3

Review update for most recent version:
Uhh Ill get used to the new UI but I miss the swiping across features the last version offered. Swiping down brings the Notification Center down accidentally which is irritating.
