Sharpen your concentration in five minutes a day. Schulte Table is a calm brain game for focus, attention and visual speed. Find the numbers in order while keeping your eyes on the center of the grid β one simple rule that trains your peripheral vision, concentration and reading speed. This isn't a gimmick. The Schulte table was created by psychiatrist Walter Schulte to study attention, and it has been used for decades to build focus and faster reading. HOW IT WORKS β’ Keep your gaze in the center β’ Find the next number or letter with your peripheral vision β’ Tap the targets in order β’ Beat your time and make fewer mistakes MAKE IT YOUR OWN β’ Numbers or letters β’ 3Γ3, 4Γ4 and 5Γ5 grids β’ Count up or count down β’ Shuffle and rotated-cell modifiers when you want a real challenge β’ Clear results after every round and a training log with your streak Start easy and climb. Kids build recognition and attention; adults get a fast mental warm-up that beats another scroll through the feed. CALM BY DESIGN β’ No ads, no noise β’ With Premium, train fully offline β’ Light and dark themes β’ iCloud sync for your history and settings across your Apple devices β’ Available in 12 languages FREE AND PREMIUM β’ Play one free session every day β’ Premium unlocks unlimited sessions THE HONEST PART The Schulte table is real attention training, not a magic pill. We don't promise IQ points or medical outcomes. The results come from showing up and doing the rounds. Missing a feature?

Curium

Curium is the feed you leave knowing something new. You already scroll every day. Might as well come out of it more curious. Curium turns knowledge into vertical cards: one idea at a time, and something to tell someone tonight. History, science, geography, art, economics, languages, technology β you pick your topics and your level, and the app builds your feed. HOW IT WORKS β’ A vertical feed of knowledge cards: you scroll, you learn. β’ Quick quizzes to check it actually stuck. β’ "Go deeper" on any card when a topic grabs you. β’ The Daily Quiz: the same questions for everyone, so you can compare scores with friends. WHAT KEEPS YOU COMING BACK β’ A daily goal built to last: 4, 6 or 10 cards. β’ A streak to protect, plus quests and badges to earn. β’ XP for everything you do, and a weekly league that resets every Monday. β’ A review queue that brings an idea back just before you'd forget it (spaced repetition). β’ A mastery bar for each topic: how much of the catalog you've really learned. Because scrolling isn't learning. β’ A Home Screen and Lock Screen widget: today's question, and your streak. SHARE IT β’ Turn a card into an image for your story. β’ Send a friend a challenge: they answer the same question, whether or not they have the app. WITHOUT A SUBSCRIPTION β’ 4 new lessons a day, plus one more by watching an ad. A lesson you've already opened stays open. β’ 20 reviews a day. β’ Beginner and Intermediate levels. β’ One path a month, yours to keep forever. β’ Ads. CURIUM+ (OPTIONAL SUBSCRIPTION) β’ No ads. β’ Unlimited lessons, and your whole review queue the same day. β’ Every difficulty level, up to Expert. β’ Every path: one topic, a known number of cards, and a real ending. β’ Offline mode: take a path or your reviews on a plane, a subway ride or a vacation. β’ A streak shield that recharges: miss a few days without losing everything. WHAT WE DON'T DO We never read your contacts, your photos or your location. Your data is hosted in the European Union.

Verdict
The clearest difference is ads: Schulte Table at none against Curium's shown. Curium's advantage is update cadence (every 3 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
