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. }

Non si collega ad Apple Watch, se era specificato non l’avrei acquistato . Acquisto inutile, soldi regalati

bluetooth연결을 누르면 계속 앱이 자동으로 꺼집니다. 앱을 몇 차례 삭제해도 똑같은 문제가 반복됩니다. 환불 부탁드립니다.

The app crashes after clicking the export button. Export via iTunes and Dropbox also doesn’t work.

App con un forte potenziale, io la utilizzo tantissimo sui miei clienti. Ho messo 3 stelle perchè è piena di bug e dovrebbero implementare altre funzioni. Ad esempio, quando metto il marcatore eventi, non aggiunge nessun evento, agevolare l’esportazione del file. Naturalmente da sola funziona poco, io implemento l’analisi del file con kubios che richiede un procedimento più lungo. Dovrebbero migliorarla di parecchio, con tutta l’AI di cui disponiamo oggi, è rimasta ancora molto indietro, vive ancora della sua vecchia gloria.

Great app, simplistic and straightforward. I use it for collecting raw RR data. The option for in app time stamping is great. Sadly could only upload the first reading to dropbox. None after. Very poor bug. Can use the email function though.

Please make a connection with FitBit Sence 2. Then 5 stars.

The app inexplicably lost its ability to export files to Dropbox. I’ve tried deleting both Dropbox AND HRV Logger in an effort to make it work again (and lost all my data in the process). Still doesn’t work. Given the limitations of the app itself, exporting the data is critical. This loss of functionality severely handicaps the app.
