■Ghosty — iOS App / Launching 2026
Cut the noise. Stay focused.
Ghosty is a self-management and focus app designed to isolate users from the digital noise of modern life and unlock deep, sustained concentration.
Concept & Features
- Minimal UI for deep immersion — A dark, stoic design with vivid mint green accents. Goals, progress, and routines are laid out vertically with visual noise stripped to the minimum.
- Total notification blocking (Screen Time API) — During focus sessions, notifications from other apps are shut out at the system level. Your phone becomes a tool, not a distraction.
- Metabolism — honest self-assessment — Integrated with Apple HealthKit, Ghosty scores your physical condition based on real data: sleep duration and step count. No flattery. Just facts.
- Deep calendar sync — Completed focus sessions are seamlessly logged to your native Apple Calendar, building a visible record of your effort over time.
PIN STUDIO built Ghosty for professionals and creators around the world who want to reclaim their time — and mean it.
