Every app ships with the metric built in.
Each Seltok app runs a skill-building loop you can measure in days. Plays like a game so you return; works like a tool so returning matters.
Four apps. Each one measurable.
ReflexLog
WordDelta
GridMind
FocusRun
Tap-based sessions log your reaction time to the millisecond. Two weeks of daily play surfaces a trend line you can act on.
Daily five-minute sessions track your recall accuracy per word set. The metric is retention rate, not points earned.
Pattern sequences grow with your score. The app records your best spatial recall depth and flags when you plateau.
Structured focus blocks with no artificial padding. Your logged duration per day is the only number that matters.

Enough daily sessions to see whether a metric is moving. If it isn't, the loop isn't working — and you'll know.
Repeatable daily session length. Tight enough to keep the habit; long enough to generate meaningful data.
Each app tracks exactly one outcome. No dashboard bloat — one number tells you whether today was better than yesterday.
Pick one. Use it for two weeks.
All Seltok apps are free to try on Google Play. The metric doesn't lie — you'll know quickly whether it's working.
