Those who truly change are quiet. They don't announce it. They don't compare. They simply build. Ghosty is not just a tool for getting things done. In an age of information overload, it's a space to go ghost — to become invisible to the noise and the eyes of others — and face your goals alone. Building daily routines, moving quietly toward what matters. This is not mere productivity. It is self-expression. Ghosty was built for those who design their own lives, dive deep, and live in a state of quiet obsession. ■ Mint Green That Shifts Your Mind The moment you open the app, a vivid mint green accent catches your eye and triggers the switch into deep focus. An immersive design, stripped of everything unnecessary. ■ A Linear UI That Clears Your Thinking Goals, progress, and daily routines — arranged in a clean, vertical flow with nothing wasted. No hesitation in your eye or your hand. Only what you need to face right now rises clearly into view. ■ The System That Sustains Immersion Full Phone Lockdown (Blackout) During a session, access to social media and video apps is physically blocked. No willpower required — the environment simply doesn't allow it. Visualize Your Investment Toward Goals Before each session, link your goal (Mission) to what you'll do (Action). Time doesn't just count down — you feel it accumulating as investment. Self-Control Over Dopamine After each session, rate your focus quality on a five-point scale. Reading earns a positive score. Mindless scrolling earns a negative one. Self-control becomes a skill. Proof of Your Journey (Apple Calendar Integration) Every session is automatically logged to your calendar. Alongside your journaling, it quietly documents the ground you've covered. ■ Why We Built This We believe there has never been a greater need to disconnect from the noise and listen to your own inner voice. The name Ghosty is a nod to "ghost mode" — a concept from self-development culture that means temporarily cutting ties with the outside world to go all-in on personal growth. Not just optimization. A way to make the everyday beautiful. This space is for those with their own unshakeable aesthetic. Not to show anyone. Not to compete with anyone. No social features. No rankings. Core features are free and open to all users. About the Pro Plan Unlimited Action creation, full history insight analysis, iCloud backup, and more — the Pro Plan unlocks the complete system. Your first 14 days are free. It's just you and your goals. Be a Ghost. Stay Focused. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
