Regularly vs MentalMather

Regularly gives you five original puzzles a day, one from each game. A new set arrives every morning, so there is always something waiting and always a reason to come back. No streaks to keep alive, no clock ticking at you. Just a few quiet minutes of logic, words, and mental math to get your head going. FIVE PUZZLES, EVERY DAY Kingly. Place one king in every row, column, and color region, and never let two touch. Gentle logic in the spirit of Queens and Sudoku. Countable. Combine the number tiles with + - x ÷ to hit the target. Quick mental math that is never the same twice. Floored. Trace the hidden words and the letters cascade down, so the board shifts under you with every move. Half word search, half falling blocks. Paths. Add light bulbs until every square is lit. Numbered walls tell you how many bulbs belong beside them. A bright take on light-up logic (Akari). Thred. Follow a path through the letters to spell each hidden word. A word search with a thread to pull. A HABIT THAT FITS YOUR DAY Play on the train, over coffee, or just before bed. Finish the set, share how you did, and see how your friends got on. WHAT YOU GET A brand new set every single day. Five different puzzles across logic, words, and numbers. Results you can share. And a clean, calm design that stays out of your way. Regularly speaks English, German, Spanish, French, Japanese, and Chinese (Simplified). Play one puzzle today. You will probably stay for all five.

MentalMather measures your daily cognitive performance through mental math — not to teach you math, but to measure how sharp your brain is right now. HOW IT WORKS Take a quick Sharpness Test each day. The app compares your speed across addition, subtraction, multiplication, and division against your own historical baseline. The result is your Sharpness Score — a personalized metric that tells you whether you're performing above or below your norm. This isn't about getting better at math. It's about measuring your cognitive throughput. When your working memory is firing on all cylinders, you solve problems faster. When it's not — due to poor sleep, stress, or fatigue — your score reflects that. FEATURES - Sharpness Score — your daily cognitive performance metric, personalized to your baseline - Guided Assessment — finds your ideal difficulty level automatically - Quick Play — practice at your own pace with customizable difficulty, timing, and operations - Challenge Mode — create challenges and share them with friends via code or QR, then compare results - Detailed History — every session tracked with per-problem breakdowns and solve times - Stats & Analytics — sloppiness tracking, personal bests, per-operation performance - Light & Dark themes — premium dark mode with metallic design, clean light mode - Haptic feedback — feel your correct and incorrect answers - Works offline — all your data stays on your device WHY MENTALMATHER Most brain training apps are games disguised as science. MentalMather is a measurement tool. Your Sharpness Score compares you against yourself — not against strangers on a leaderboard. The question isn't "are you good at math?" It's "how sharp are you today compared to your own baseline?" Built for people who care about their cognitive performance and want a quick, honest daily check-in.
