Heart Rate Variability Logger vs H7 Active

Heart Rate Variability Logger lets you record, plot and export time, frequency and non-linear HRV Features (includes experience sampling, RR-interval correction, DFA alpha 1 for aerobic threshold estimation in real-time, comparison between recordings, activity monitoring & step counting, location tracking). Heart Rate Variability Logger requires a Bluetooth Low Energy (also called Bluetooth Smart or BLE or 4.0) heart rate sensor (we recommend Polar H7 or H10) Main features: - Extracts, plots, stores and exports heart rate, rr-intervals, time and frequency domain heart rate variability features (AVNN, SDNN, rMSSD, pNN50, LF, HF, LF/HF, alpha 1 from DFA) - Configurable experience sampling for events annotation - Comparison between up to 3 recordings lets you get a better understanding of differences in HRV under different contexts in a glance. The comparison modality includes also Outlier removal - Activity tracking: step counter or accelerometer derived motion intensity for user context (step counter only for iPhones 5S) - Location tracking, either using GSM/WiFi networks (low battery consumption) or GPS (high accuracy) - Configurable time window for features computation (choose between 30 seconds, 1, 2 or 5 minutes) - RR-intervals correction can be enabled to prevent ectopic beats or artifacts from affecting HRV features - export for Kubios - Filters data based on the selected threshold - Shows HR in the app icon - Data export using iTunes or Dropbox - Tested for recordings longer than 24 hours Please note that continued use of GPS running in the background can dramatically decrease battery life.

H7 is a calm, honest way to build a lifelong movement habit. Instead of chasing streaks or shouting PRs, H7 asks one simple question: are you getting enough hours of real movement a week? Final goal - one hour a day - level of activity associated with a long, healthy life. Everything in the app is built around helping you get there at your own pace, from H0 (almost no movement) up through H7. A BELT SYSTEM YOU ACTUALLY FEEL Every week of consistent movement earns progress toward your next belt — white, yellow, orange, green, blue, brown, black. Seven levels (H1–H7) tell you exactly where you stand, what's next, and how far you've come. 100+ ACTIVITIES, ONE CATALOG Walking, running, cycling, swimming, climbing, yoga, martial arts, dance, team sports, hiking -pick what fits your life. Each activity is calibrated so a 45-minute hike counts like a hike, not like a marathon. WORKS WITH APPLE HEALTH H7 reads your workouts from Apple Health automatically - the treadmill, the park run, the swim you logged with your watch. No double-entry, no guilt about forgotten sessions. QUIET, PRIVATE, YOURS No follower counts. No feeds to doom-scroll. No ads. Your data lives on EU servers, encrypted in transit and at rest. You can export or delete everything from the Profile screen at any time. MULTILINGUAL Czech, English, Slovak — the app follows your device language, or you can pick. H7 is for the beginner taking their first brisk walk, the parent squeezing movement between school runs, and the seasoned athlete holding the line at H7. Start where you are. Move a little more tomorrow. Learn more at https://h7-web.vercel.app/
