Your focus has a face — a tiny head of lettuce that thrives when you focus and wilts when you doomscroll. Block distracting apps. Watch your lettuce come back to life. MEET YOUR FOCUS BUDDY Your lettuce isn't just a mascot. It's an honest little gauge of how you're treating your phone. Run a focus session and it perks up. Burn an hour on TikTok and… well, you'll see. No guilt trips, no shame spirals — just a vegetable that tells you the truth. BLOCK ANYTHING THAT DERAILS YOU Powered by Apple's official Screen Time framework, so blocks actually stick. • Block specific apps — pick Instagram, TikTok, X, games, anything • Block whole categories — Social, Entertainment, Games FOCUS YOUR WAY • Manual sessions — one tap, focus right now, any length • Recurring schedules — build a rhythm (deep-work mornings, phone-free evenings, weekends off) • Lock screen Live Activity — your lettuce and a live countdown, right on the lock screen • Overnight and short sessions both supported — five minutes or eight hours A HEALTH SYSTEM THAT REWARDS REAL FOCUS Every minute of focus grows your character's aura. Every minute on a blocked app dims it. Going way over your daily screen-time goal? That costs you too. It's a continuous, visual picture of your relationship with your phone — not a fragile streak you'll rage-quit the moment you slip. STREAKS, BADGES & DAILY GOALS Set a daily focus goal and build a streak by hitting it. Unlock fun badges for back-to-back sessions, marathon focus days, and consistency milestones. Watch your longest streak grow over weeks and months. FRICTION WHEN YOU NEED IT Tempted to bypass the block? You'll have to work for it. Sessions can't be cancelled on a whim, and the app refuses to be your accomplice. VACATION MODE Heading offline, traveling, or just need a day off? Flip on vacation mode to pause everything cleanly, without losing your progress. PRIVATE BY DESIGN Everything stays on your device. The app uses Apple's official Screen Time APIs — your usage data never leaves your phone, never touches our servers, and we couldn't see it if we tried. HOW IT WORKS 1. Pick the apps and websites you want to block 2. Start a session — manual right now, or scheduled to repeat 3. Stay focused, watch your lettuce flourish Get the focus app that's gentle, honest, and refuses to lie about your scrolling. Your future fresh self is waiting. *All features described above require a subscription.* Terms of Use: https://lettucefocus.com/terms Privacy Policy: https://lettucefocus.com/privacy

Verdict
The clearest difference is monetization model: Brainlock at freemium against Lettuce's subscription. Brainlock also leads on iOS requirement (16.0 vs 18.6). Lettuce's advantage is rating (5.0 vs 4.6) and update cadence (every 5 days vs every 2 weeks). On price, ratings volume, ads and in-app purchases there is nothing between them.
