Most apps guess. Cortex measures. A 60-second reaction time test every morning gives you a focus score against your own baseline. Then one-habit experiments show whether sleep, caffeine or a new routine actually changed it: real effect, no effect, or inconclusive. YOUR MORNING SCORE - A 60-second reaction-time test, taken in your own morning window - Scored against your personal baseline — never someone else's average - Streaks, shields, and ranks that reward showing up REAL EXPERIMENTS - Change one variable: caffeine cutoff, phone-free first hour, shorts curfew, cold finish, and more - Cortex compares your baseline days against intervention days - Verdicts are graded by evidence strength — A, B, or C HONEST BY DESIGN - If the result is noise, Cortex says so: "no meaningful effect" is a real answer - No made-up insights, no dressed-up randomness - Correlations are labeled as hints, not verdicts TRENDS AND CONTEXT - 14-, 30- and 90-day trend charts around your personal noise band - Optional Apple Health context: sleep, heart-rate variability, resting heart rate and steps alongside your scores - Your data stays on your iPhone — no account, no cloud; full CSV export any time SUBSCRIPTION REQUIRED Cortex is a paid app: a subscription (or the one-time Lifetime purchase) is required to use it — there is no free plan.

Laps turns every swim into a score. Log a session and Laps rates it against the World Aquatics 0 to 1000 scale, the same scale the sport itself uses, so you finally know where you stand. Not a vague "good workout", but a number you can chase. RANK THAT MEANS SOMETHING Your times are scored properly, by event and by course, and placed on a global leaderboard and one for just your friends. Personal bests are kept for every event you swim, so you can't miss a beat. YOUR HISTORY, IN SECONDS Already race? Screenshot your personal bests on SwimRankings or SwimCloud and Laps Pro reads them in for you. Check the list, tap import, done. KNOW WHAT YOU NEED Laps Pro shows the exact time that moves you up to your next rank, in your favourite stroke. STREAKS BUILT FOR SWIMMERS A streak in Laps is a span of days, not a swim every single day. Four days between sessions keeps it alive, because that is how swimming actually works. Two savers a month cover the week that got away from you. TWO WAYS TO RECORD Log a casual session in seconds: lengths, time, done. Or run a timed trial that counts towards your rank. FRIENDS, NOT FOLLOWERS Friendship in Laps goes both ways. Nobody appears on your leaderboard without being asked first, and private accounts stay private. TRAINING PLANS Nine plans and over 100 workouts, from first lengths to sprint sets, written for real pool sessions. IN SEVEN LANGUAGES English, Spanish, French, Italian, Dutch, Russian and Japanese. LAPS PRO Laps is free, and the parts that matter most stay free: global and friends leaderboards, streaks, personal bests and recording swims. Laps Pro adds your full points history, the training plans, rank projections that show what your next division needs, and regional leaderboards. Monthly or yearly, with a free trial for new subscribers. Cancel your subscription any time. Laps is not a coach and not a medical device. Talk to a doctor before starting a new training routine, and never swim alone or beyond your ability. Laps is not affiliated with, endorsed by, or connected to World Aquatics. Scores are calculated from published formulas and published times. Terms of Use: https://laps-app.com/terms Privacy Policy: https://laps-app.com/privacy
