Cardio Log

The workout is done. Open CardioLog, tap the sport, set the minutes, rate the effort β€” logged in ten seconds. That is the whole job: a dead-simple cardio journal for people who run, cycle, swim, row or hit the elliptical and just want the work written down. No GPS to babysit. No pace charts to decode. No feed of strangers going faster than you. CardioLog measures nothing β€” it remembers. You did the session; the app keeps the receipt, adds it to your week and shows how close you are to the 150 minutes of aerobic activity the WHO recommends for adults. WHAT YOU GET β€’ A session logged before your breathing settles β€” sport, minutes, effort, done β€’ Your week at a glance: 112 of 150 minutes on Thursday tells you exactly what the weekend owes β€’ A streak counter that makes day 14 feel too expensive to break β€’ Your training mix laid bare β€” when "I swim sometimes" turns out to be 2 swims in 30 sessions, you will know β€’ A monthly summary card ready to share: sessions, minutes, active weeks, longest session and your activity mix β€’ Edit any entry, add notes ("hill repeats", "new shoes"), and export your entire log as CSV anytime PERFECT FOR β€’ Runners and cyclists who want a diary of the work, not another GPS trace β€’ Swimmers, rowers and elliptical regulars whose sports GPS apps never handled well anyway β€’ Anyone chasing the WHO 150-minute week, one logged session at a time β€’ Lapsed athletes rebuilding the habit who need a streak more than a coach WHY NOT JUST A GPS TRACKER? Trackers record where you went. A journal records that you went. If maps and splits kept you consistent, you would be consistent already. CardioLog strips the workout down to the three facts that build a habit β€” what, how long, how hard β€” and turns them into a week you can see and a streak you will not want to lose. PRIVATE BY DEFAULT Your log lives on your device. No account, no location, no third-party SDKs. A daily reminder at the hour you choose is the only time CardioLog speaks first. It is an activity journal, not a medical device β€” it measures nothing and assesses nothing. FULL ACCESS CardioLog Pro unlocks the complete experience: the daily volume chart, your training mix by sport, streak tracking and the shareable monthly summary. Choose a Weekly or Yearly subscription, or a one-time Lifetime purchase. Tonight, after the run β€” log it. That is how streaks start. SUBSCRIPTION TERMS Weekly and Yearly are auto-renewing subscriptions. Payment is charged to your Apple Account at confirmation of purchase.
