Have you tried health mobile apps? Which one improves your health behavior?

Yes , but what kind of heath mobile app you are talking about, we built and worked on physicians dictation app, in  which physicians or doctors logs their record through voice recognition system .

It will help them to record instantly any prescribed suggestion or note.

Yes i did use some apps like Samsung Health & Heathy Diet

I am using google fit(a good app from google), it help you track physical activities(walking,running,biking) and record of weight.

yes, it's very useful to track my exrcises and heart rate .

non jamais sur le programme application

Your Health Behaviour improve over How you work or do exercise daily. 

there are lot of application Available in Market, Some comes with Fitness device monitoring integration, for that you need to buy fitness device. Some Basic device gives you information about, Steps you walked, Heart rate etc. 

Google Fit is the best application for daily tracking of your Workout.

It's not accurate. It's just a monitoring app but don't rely on it.

The weight of the weight is only a matter of attention.

We all know that there are *tons* of health apps out there.  Seemingly a new one everyday.  Apple's AppStore has ~7,100 health related apps, Droid has ~1,300, and even Blackberry has ~300 as of Nov 2010 according to the report from mobihealthnews (and given the historical growth of health apps, these numbers surely have increased).

I think there is very little a health app can do, if not coupled with an external sensor. I have used and still use various smartwatches with a heartbeat monitor, a connected scale and a connected blood pressure meter. They are all good, but honestly none of them have managed to induce myself to take care of my behaviour (which is bad). Actually, recently, a doctor has, by scaring me. And I am not joking: probably Apps should become predictive and be able to tell us where we heading if we don't change.
