Heart Rate Variability HRV Camera 2.0 [free]

Check: Heart rate (Pulse), Heart Rate Variability (HRV), Fitness and Stress level, Cardio calculations track progress and more using only camera.
Usage: Finger should cover camera lens completely (not only flash). During capturing, camera preview should be red and real time graph (right, near preview) should display
quasi-periodic signal, find optimal position not to burn your finger by flash.

Application provides summarized analysis results (as classes starting from Poor .. to Athlete) using HR and HRV (Heart Rate Variability) analysis, as well as data for
sharing and crowdsourcing on the ECG for Everybody.
ECG for Everybody is mobile, complete solution for heart health, fitness and stress level check.
Crowdsourcing in the application is available to everybody to check health, fitness, to compare with others. Participate in the Crowdsourcing, provide useful comments and
receive much more of them, get the wisdom of the crowd. Invite your friends who has medical or fitness knowledge to review data, let's share knowledge and make it available
for everybody. Our vision is to aggregate all knowledge in heart health, fitness and related fields and to provide it to everybody as well as to connect users in strong
smart heart care network.
Some of data may be used for Big Data collecting, they will be completely anonymized (stored and used).
Some analysis interpretation instructions:
Normal resting heart rate for adults ranges from 40 to 70 beats a minute. Lower heart rate at rest implies more efficient heart function and better overall fitness.
Heart Rate Variability
HRV correlates with heart health, stress, athletic training, emotional health, and fitness.
rMSSD (Root Mean Square of Successive Differences) is strong overall Fitness level indicator. Try to have rMSSD greater than 40ms, track your progress in app history
graph.
HRV graphs show changes in pulse.
Poincaré Plot shows changes in successive heart beats, good dispersion is over the main diagonal.
Spectral analysis
Shows the balance in ANS (Autonomic Nervous System).
LF/HF is one of nervous balance indicators (low stress) and good values are close to 1.
For reliable results duration should be 2min+.
Cardio
Get benefits from Cardio using zones calculation and instructions in the app.
Analysis duration
In general, longer analysis provides more reliable results.
* 10-15 seconds is sufficient for Heart Rate
* 30 seconds analysis provides HRV measurements
* One minute analysis provides more reliable HRV measurements
* Two+ minutes analysis is necessary for reliable spectral analysis
ECG for Everybody
ECG provides more accurate results, check ECG for Everybody: Mobile, complete, Heart health check solution which transforms smartphone to the ECG station, provides fitness,
heart health analysis and connection with others through sharing and crowdsourcing http://ecg4everybody.com. Our tests show that PPG based heartbeat detection may have less
than 2% error in comparison with ECG based detection.
ECG for Everybody http://ecg4everybody.com is in early stage and we are open for comments, critiques, advice, cooperation.
Our Mobile ECG sensing extender is ready for pre-orders. It is an unoque mobile ECG sensing solution which can operate without electrodes and capture up to six ECG channels
with dozen lower manufacturing price design.
Get familiar and with additional solutions like ECG generator which is mobile app with peace of gear which transforms mob app generated signal to the real ECG which can be
captured using any real ECG device, including our. [email protected]
It's good to have flash close to the camera to provide lights through finger, otherwise try to provide good light conditions.
This is not a medical app.
