Senwitt is a brain exercise app. Not brain training. Not therapy. Just daily practice for your mind. Open Senwitt. Pick a Skill. Do a Set. Keep your streak. That's the loop. WHY EXERCISE, NOT TRAINING Brains run on "use it or lose it." Senwitt is built on daily practice — short Sets that take 5 to 7 minutes, fresh every morning. Like Strava for running or Peloton for fitness, Senwitt makes showing up the point. WHAT'S INSIDE • Daily Sets — fresh every morning • 30+ Skills — memory, focus, word, logic, reaction, pattern, math, attention • Sharpness Score — your daily snapshot • Belt progression — from white belt to black belt, earned set by set • Streaks — your daily exercise habit, visible • Witt — your mascot. Witt notices when you skip. A DIFFERENT KIND OF BRAIN APP Senwitt is for daily puzzle fans, people who feel their attention span shrinking, and humans who want the discipline of a fitness app applied to the mind. If you finished a daily word puzzle and wondered "what's next," Senwitt is what's next. THE DAILY MECHANIC • Morning Set — a fresh puzzle and Skill rotation • Coffee Break Set — under 3 minutes when life is busy • Weekend Long Set — when you have the time • Witt's Picks — Skills Witt thinks you've been avoiding SENWITT UNLIMITED Senwitt Unlimited unlocks the full Skill library, advanced belts, the full Set archive, and an ad-free experience. Subscribe monthly or yearly. Cancel any time — your streak stays. WHAT SENWITT IS NOT • Not a brain training program with cognitive transfer claims • Not a medical device • Not an IQ test • Not a 20-minute homework assignment • Just brain exercise. Daily. BRAIN EXERCISE, EVERY DAY Show up. Do a Set. Watch your Sharpness Score. Earn your next belt. That's the whole app. The streak is the workout. The Sharpness Score is the mirror. WHO IT'S FOR • Daily puzzle people • Anyone whose phone has been winning lately • Fans of daily-mechanic apps like daily word puzzles, sudoku, crossword and brain teasers • People who like the gym, but for the mind PRIVACY We don't sell your data. Your Sharpness Score stays on device unless you opt in to backup. Full policy at senwitt.com/privacy. SUBSCRIPTION Senwitt Unlimited auto-renews until cancelled.

Verdict
The clearest difference is in-app purchases: 1ISL Challenge at none against Senwitt's 1. 1ISL Challenge also leads on ads (none vs shown) and update cadence (every 2 days vs every 5 days). Senwitt's advantage is iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.
