Once upon a time, TestFlight didn't exist. If I made an app for someone, well, they'd have to copy > paste a bunch of stuff from their phone. Bug tracing sucked, because you never knew the exact conditions. I designed up an app that would capture the iPhone's data, then empower the user to share that info to their developer or others.
Because good brands sell better, I took the time to infuse it with some style. As a big "Thank you!" to the team who worked on the in-house project, I drew little illustrations of each contributor. Full of animation, interactions, and transitions, metaSauce was a great little commercial for Rocksauce.
