Today I'm launching my new app, Hacktivate. It teaches real-world computer science skills through 240 "capture the flag" challenges, and works on iPhone, iPad, and Mac with one purchase. I've poured a ton of love into it, and I'd love to hear what you think 🙌 (Link in reply)

I've updated @GymHero_app with a new animated mesh gradient background, paired with thin translucent material cards that create depth by revealing the fluid motion underneath. The animations are rendered with a custom Metal shader to keep everything smooth and performant.…
