A tiny macOS fidget app: a pixel pig that glides gently across your screen.
A calm, repetitive bit of motion to fidget on while you read, think, or breathe.
No clutter. No Dock icon. Tiny menu bar icon. 🤏🏽
🐷 flies bilaterally · 🖱️ change the speed · 🅿️🅸🅶🆂🅵🅻🆈 letters
I live with anxiety and ADHD, and reading long blocks of text can be hard: my eyes skip and my mind wanders. One day I set a pixel pig flying across the top of an article and read underneath it. It just worked.
- 🌿 The gentle, repetitive motion settles my nervous system, like watching waves.
- 🌀 The pig adds just enough variation for my ADHD brain. A small visual fidget, kind of like brown noise but for my eyes: enough to stay engaged, not enough to distract.
If your brain works like mine, I hope it helps you too. 🐷💛
- ⬇️ Download the latest
Oinkulus.dmg - Open it and drag Oinkulus into Applications.
- First launch: this build isn't signed by Apple yet, so macOS will say it "can't be checked." Go to System Settings → Privacy & Security, find the Oinkulus notice, and click Open Anyway. One time only. ✅
🐷💛 Oinkulus is not a medical device and makes no clinical claims.
Oinkulus has no window. It starts flying the moment you open it and lives in your menu bar as a 🐷 (which turns to 💤 when paused).
To read with it: open any article, PDF, or doc and let the pig fly over your text. It's click-through, so you can still scroll, click, and select normally. Press ⌘⇧E anytime to pause or resume.
| Menu item | What it does |

| Speed | Slow, Medium, Fast |
