Phone Call Application - CallStop

I recently worked on the designs for an early stage iOS mobile application called CallStop. CallStop allows users to control who is able to reach them, acting as a firewall for their phone.
You can view the case study for this at https://www.morgangibson.design/callstop-case-study
I also created App Store images, which you can see at https://apps.apple.com/us/app/callstop-block-robocalls/id1455892856
