Your feed costs a move now. ChessScroll seals the apps that eat your evenings — Instagram, TikTok, YouTube, whichever you choose — behind a chess puzzle at your level. Solve it and you earn minutes of scroll. Fail it and the position waits. That's the whole app. That's the whole deal. THE DEAL 1 puzzle = minutes of scroll. You set the exchange rate. HOW IT WORKS 1. Seal your apps. Pick the ones that eat you. 2. Reach for one, and a puzzle appears instead. 3. Solve it. The app opens and your clock starts running. 4. Minutes run out mid-scroll? In chess we call that flagging. Solve another. WHY IT WORKS You already reach for your phone dozens of times a day. ChessScroll doesn't fight that urge — it reroutes it. Every reach becomes one tactic at your level: twenty to forty seconds, and a real fight. It's the training every coach prescribes and nobody actually does, attached to a habit you already have. TWO NUMBERS, FACING EACH OTHER — Your puzzle rating, climbing. — Your daily screen time, falling. Everything else is supporting cast. REAL PUZZLES, AT YOUR LEVEL Nearly fourteen thousand positions from real games, each one rated by the players who tried it before you, and served at your rating rather than under it, so the rating you build is earned. Works fully offline. From 400 to 2700, the puzzle fits. THE CLIMB Fourteen chapters, one for each master: Morphy, Anderssen, Steinitz, Lasker, Capablanca, Alekhine, Botvinnik, Nezhmetdinov, Tal, Petrosian, Spassky, Fischer, Karpov, Kasparov. Every six puzzles you solve lays a stone on their road, and the one you solved at midnight to get into Instagram counts the same as the one you chose to play. The road stops at twenty-eight of their own games, and every one you solve goes into your album as a card. You never have to open the tab for it to move. NO NEW ADDICTION Training sessions end by design. No infinite puzzle feed, no guilt notifications, no nagging. Paul Morphy said in 1859 that chess should never engross the mind. We're inclined to agree. PRIVACY Your app choices and screen-time data never leave your device — Apple's Screen Time framework enforces that by design. No account needed. MEMBERSHIP ChessScroll requires a membership: yearly with a 7-day free trial, or monthly. Subscriptions auto-renew until cancelled in Settings.

Verdict
The clearest difference is in-app purchases: Blue Control App at none against ChessScroll's 2. Blue Control App also leads on device support (3 vs 1) and iOS requirement (14.0 vs 17.0). ChessScroll's advantage is update cadence (fortnightly vs every 2 months). On price and ads there is nothing between them.
