Most productivity apps assume more lists, more tracking, and more pressure will fix your follow-through. Prolific Companion is built on the opposite hypothesis: you already know what matters. You just need one thing each day and a calm voice that actually checks in. START WITH YOUR ARCHETYPE A 28-question instrument places you in one of seven productivity archetypes — patterns for how people actually start, sustain, and finish work. Your archetype shapes how Proli (your companion) talks to you. A Novelty Seeker gets one kind of prompt; a Structured Achiever gets another. The voice matches who you are, not who an average productivity app assumes you to be. THE DAILY LOOP • Morning: Proli asks what you're working on today. You name ONE thing. • Mid-day: a check-in fires. Done? Still going? Stuck? One tap. • Evening: a soft reflection on how the day went. That's it. No to-do lists. No streak-shaming. No "10x your productivity" guilt. PROLI, YOUR COMPANION Tap the floating Proli icon any time you want to think out loud, brain-dump, or just be heard. Responses are warm and short, tuned to your archetype. Conversations are private — see our Privacy Policy for how data is handled, including the AI processing that powers Proli's replies. WHAT'S NOT IN HERE No social feed. No leaderboards. No notifications begging you back. We're not a planner — we're closer to a journal that talks back. PRIVACY-FIRST Your data lives in your account and is used only to personalize your experience. We never sell personal data. Delete your account and all associated data with one tap from Settings. QUIZ FIRST Already taken the Prolific Personalities quiz on the web? Sign in with the same account and your archetype carries over.

For chess players who want to actually get better. Endless scrolling steals the hours you'd rather spend improving. Chess Shield blocks the apps that eat your chess time. Try to open one, and a puzzle takes over the screen. Solve it to get past. Every solve moves your ELO. HOW IT WORKS Pick the apps you reach for when you meant to study. Instagram, TikTok, X, whatever's eating you. When you try to open them, a puzzle takes over. Solve it to unlock the app for a few minutes. The puzzles match your level. Type your chess.com or Lichess ELO and we'll start there. Or skip the input and we'll test you with three puzzles. From then on, every puzzle is challenging enough to make you think, solvable enough that you'll get there. Insights show you which tactics keep tripping you up. Your ELO moves in real time on every solve. FREE INCLUDES – Unlimited puzzles, matched to your ELO – 6 starter tactics: Fork, Pin, Skewer, Mate-in-1, Mate-in-2, Back-rank – 1 shielded app – Full ELO tracking – Insights into what you solve and what you miss PRO UNLOCKS – All 52 advanced tactics. Mate-in-3, Discovered Attack, Zwischenzug, endgames. The full library, not just the starters. – See every blind spot. Insights unlocks every theme. Your full weakness map, no locked tiles. – Block every app you want, not just one. Plenty to start on Free. Pro is where you stop guessing what to study. 7-day free trial on the yearly plan. $4.99/month or $39.99/year. WHY IT'S DIFFERENT Most focus apps are guilt machines. Most chess apps want your scroll. Chess Shield does both jobs at once. Every minute in here is measurable progress, not just dopamine. If you've ever wished the time you waste scrolling could be real chess time, this is it. PRIVACY We don't collect anything. No accounts, no analytics, no backend. The apps you block are opaque tokens iOS hands us. We literally can't see them. Everything stays on your device. ——— Subscription details Chess Shield Pro is offered as a monthly ($4.99/month) or yearly ($39.99/year) auto-renewing subscription.
