StayGray automatically switches your iPhone to grayscale, so apps feel less magnetic and you scroll less. Your screen stays black and white by default, and you decide when color is allowed. WHY GRAYSCALE Colorful interfaces are built to grab your attention. Take the color away and the little “reward hit” gets weaker, which makes it easier to stop the endless checking without blocking any apps. CONTROL WHEN COLOR IS ALLOWED • Schedules: set work hours, evenings, or bedtime for monochrome • App exceptions: keep Maps, Camera, Photos, or any app in color • Locations: turn color on automatically at home, at work, or at the gym • Color breaks: switch to full color for a bit, then go back to gray automatically TRACK YOUR PROGRESS See how your habits change over time and estimate how much screen time you save by staying in black and white. PRIVACY FIRST No accounts. No ads. No tracking. StayGray does not collect, store, or transmit personal data.

Screen Discipline helps you set daily time limits on your most distracting apps — and actually enforces them. Set a limit. When you reach it, the app is blocked for the rest of the day. Simple, effective, no cheating. FEATURES • Set daily time limits per app (15 min – 5 hours) • Automatic blocking when your limit is reached • Daily stats to track your usage • Leaderboard — compete with friends on who uses their phone less • Earn points for staying within your limits • Hall of Fame badges for top performers at year-end HOW IT WORKS Add an app, set your daily limit. Screen Discipline monitors your usage in the background. When you hit your limit, the app is blocked until midnight — giving you back control of your time. The lower your limit, the more points you earn. Only blocked apps count — no cheating the system. SUBSCRIPTION FREE Screen Discipline Pro is a one-time purchase. No subscription, no hidden fees.
