Simple event repetition in mobile app with add/minus switch

Hi! I hope you like this interaction design for setting the repetition of the incomes and expenses on my new app, CostList, now available for download on Google Play

I previously uploaded an animation showing my add/minus switch that led me to set on and off repetitions, and if I wanted to increase the periodicity I can tap on the plus sign. This is a common interaction case so I wanted to create a special component that can solve this problem in the same spot. I'm happy to say that after doing multiple user testings, all users knew how to use this component. They seem very familiar with it even it's not!
