New: Focus Mode, Morning Lock, Creator Mode & Streaks. Block what steals your time and actually stay locked in — now with a weekly plan and a 3-day free trial. Stop killing time before time kills you. Our generation is cooked. We spend hours every day quietly handing our lives over to algorithms designed to keep us infinitely scrolling. You've already tried to cut back — and you've failed. That's why we built Lock In. Lock In is the strict app blocker that genuinely doesn't let you cheat. No 30-second delay timers, no easy bypass popups, no passcode workarounds. Set the rule once, and Lock In enforces it — even when willpower doesn't. WHY LOCK IN WORKS WHERE OTHERS FAIL: • Actually Strict System-Level Blocks — Real OS-level blocking, not a VPN overlay. The app genuinely cannot be opened. Blocked is blocked, full stop. • The Auto-Relock Enforcer — Unlocked an app to quickly post or reply? Set a custom relock timer (like 4 minutes) and Lock In catches you before you fall into the scroll, relocking automatically when time's up. • Unlock Cooldowns — Set a cooldown window between unlocks, so by the time you can get back in, you've already started doing something else. • Your Unlock, Your Way — Unlock with an NFC card or tag, with Face ID, or with a press-and-hold button. Make it exactly as strict as you need. • Focus Mode — Start a timed deep-work session and your distractions stay locked until it ends. No early exits, no "just five minutes." • Morning Lock — Keep your feeds locked when you wake up, so you get up and get going before you get online. • Scroll Myself to Sleep — A controlled wind-down window before bed (30 minutes to 4 hours), then everything locks again automatically for the morning. • Creator Mode — Need to actually post, not scroll? A temporary, partial unlock for the apps you create in — publish, reply, and get out. • Streaks — Every day you stay locked in builds your streak. Watch it grow, protect it, and share it. • True Emergency Friction — Exactly 3 emergency unlocks per month, 24 hours each. Real emergencies only. • Total Data Privacy — Everything stays on your device. No account, no server, no email required. All logic runs locally. Lock In Premium unlocks everything — unlimited apps, website and category blocking, and every mode above. Available weekly, monthly, or annually, each with a 3-day free trial. Stop wasting years of your life. Reclaim your focus, protect your mental well-being, and stay locked in. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.

Lock In just got a lot more powerful. • Focus Mode — timed deep-work sessions that stay locked until you're done. • Morning Lock — keep distractions locked until you're properly up and moving. • Creator Mode — a temporary, partial unlock for when you need to post, not scroll. • Streaks — track, protect, and share every day you stay locked in. • A new weekly plan, plus a 3-day free trial on every plan. • The block screen now adapts to whichever mode you're in. • Background re-locking and unlock reliability improvements, plus design polish throughout. Stay locked in.
