Call Wizard

Call Wizard

Call Wizard grew out of hands-on research into iOS's Call Directory Extension. The client understood the API's limitations well and shaped a product idea around them: blocking unwanted calls by NPA-NXX pattern (US numbers) using regular expressions.

I designed the app's UI from scratch and implemented the whole idea — an app extension built on the Call Directory framework, using group storage and phone-number tooling to deliver the blocking functionality.
