SkillArena: Focus Training
Four minutes of daily brain games, offline and free
SkillArena builds a daily arena from four short games covering focus, memory, reasoning, numbers and careful reading. You pick Quick (~2 min), Standard (~4 min) or Extended (~8 min), and the timer pauses if you leave mid-round. Thirteen games in total, plus modes like Deep Focus, The Tower, Daily Duel and Pressure Round.
Progress shows up as 1–100 ratings per category, weekly recaps, mastery ranks and personal records, and the app explains how those ratings are calculated. Everything plays offline with no account and no ads; optional Game Center leaderboards need a connection and display your Game Center name. The developer states no data is collected and progress stays on the device. Ratings describe in-game performance only — not an IQ or clinical score.
Why no subscription? The app is free, and the listing mentions neither a subscription nor in-app purchases.
