I made Shell Yeah, an iOS app that turns app screenshots into polished 3D device mockups
Hi everyone,
I built Shell Yeah because I was tired of spending too much time making “just one quick promo image” for app launches, updates, App Store screenshots, and social posts.
The idea is simple: drop in a screenshot, put it inside a realistic 3D device, tweak the scene, export. Shell yeah.
What it does:
- Import screenshots into 3D device mockups
- Choose canvas sizes/templates for App Store, social media, launch posts, etc.
- Pick devices like iPhone, iPad, Apple Watch Ultra, and Studio Display
- Adjust camera angle, device scale, screen zoom, and background
- Use solid colors, gradients, transparent backgrounds, or custom background images
- Apply motion presets
- Export still images or short videos
There’s a Pro version for things like removing the watermark, Pro motion presets, custom gradients, HD/4K export, and newer devices/features.
It’s made for indie devs, designers, and anyone who has ever whispered “this screenshot needs to look less sad” at 1 AM.
Would love feedback, feature requests, or brutal honesty.
