Read 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 โ€ข A session logged before your breathing settles โ€” sport, minutes, effort, done โ€ข Your week at a glance: 112 of 150 minutes on Thursday tells you exactly what the weekend owes โ€ข A streak counter that makes day 14 feel too expensive to break โ€ข Your training mix laid bare โ€” when "I swim sometimes" turns out to be 2 swims in 30 sessions, you will know โ€ข A monthly summary card ready to share: sessions, minutes, active weeks, longest session and your activity mix โ€ข Edit any entry, add notes ("hill repeats", "new shoes"), and export your entire log as CSV anytime PERFECT FOR โ€ข Runners and cyclists who want a diary of the work, not another GPS trace โ€ข Swimmers, rowers and elliptical regulars whose sports GPS apps never handled well anyway โ€ข Anyone chasing the WHO 150-minute week, one logged session at a time โ€ข 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. SUBSCRIPTION TERMS Weekly and Yearly are auto-renewing subscriptions. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the end of that period. You can manage or cancel your subscription in Settings > Apple Account > Subscriptions after purchase. Lifetime is a one-time purchase and does not renew.

About

Rackr

Read full description

Rackr is a strength-training log built for one thing: making your progress impossible to ignore. You already do the hard part โ€” showing up and lifting. Rackr turns every set you record into clear, honest feedback, so you always know what to train next, when to add weight, and where you're stalling. WHY LIFTERS CHOOSE RACKR โ€ข Fast logging that stays out of your way โ€” sets, reps and weight in seconds, with your last numbers suggested automatically. โ€ข A built-in rest timer, so every set is timed instead of guessed. โ€ข Personal records tracked automatically, highlighted the moment you hit them. SEE YOUR PROGRESS, NOT JUST YOUR HISTORY โ€ข Per-exercise progression charts with estimated 1RM trends โ€” watch your strength curve climb week over week. โ€ข Weekly and monthly volume, session and time stats that show whether you're truly overloading. โ€ข Stall detection that flags a lift before weeks slip away. โ€ข A muscle map that reveals which groups you're hitting โ€” and which you're neglecting. TRAIN THE WHOLE BODY โ€ข Build and save your own routines โ€” Push/Pull/Legs, upper/lower, full body, whatever you run. โ€ข A guided abs program: 12 core exercises with 3D form demos and timed intervals โ€” no equipment needed. โ€ข Track body measurements โ€” weight, body fat and more โ€” and set goals you can watch yourself close in on. YOUR DATA, YOUR WAY โ€ข A clean, distraction-free dark interface designed for the gym floor. โ€ข Sign in with Apple or Google, with secure cloud backup so your history survives a new phone. โ€ข Private and ad-free. Your training is yours โ€” never sold, never buried under ads. RACKR PLUS Unlock the full analytics suite โ€” deep progression insights, stall alerts and advanced trends โ€” with Rackr Plus.

Download Rackr and make every rep count. โ€” Rackr Plus is an auto-renewable subscription, available as a monthly or a yearly plan, billed through your Apple ID.
