See how you're holding up with your training plan at a glance! This extremely basic app shows you how far you ran each day, and what your weekly total is. Did you manage to reach the distance your training plan suggests? To use Rundays, all you need to do is log your runs in any app compatible with Apple Health.
Cardio Log
Read full descriptionHide full description
The workout is done. Open CardioLog, tap the sport, set the minutes, rate the effort โ 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 โ 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 โข A session logged before your breathing settles โ sport, minutes, effort, done โข Your week at a glance: 112 of 150 minutes on Thursday tells you exactly what the weekend owes โข A streak counter that makes day 14 feel too expensive to break โข Your training mix laid bare โ when "I swim sometimes" turns out to be 2 swims in 30 sessions, you will know โข A monthly summary card ready to share: sessions, minutes, active weeks, longest session and your activity mix โข Edit any entry, add notes ("hill repeats", "new shoes"), and export your entire log as CSV anytime PERFECT FOR โข Runners and cyclists who want a diary of the work, not another GPS trace โข Swimmers, rowers and elliptical regulars whose sports GPS apps never handled well anyway โข Anyone chasing the WHO 150-minute week, one logged session at a time โข 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 โ what, how long, how hard โ 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 โ 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 โ log it. That is how streaks start.
