A week of daily use

1) bracelet: 4 stars / 5
+: Accurate to count steps; available time replaces a simple watch (small least: a) must be pressed and the screen lights up and b) no date); good battery: almost 2 weeks without charge!
- Illegible display outside (too bad for the time!); fixing goodbye. Not easy to attach and I doubt it resists time. Nothing beats a good watch strap loop.

2) myTerraillon application (installed on my smartphone running android 4.4.4 kitkat) to track the history: 3 stars / 5
Merit only 3/5 because the instructions are very very incomplete. After a week, I put 4 stars because I realized after a week what to do:
Enable Bluetooth (leave the constantly active) and let it happen! The advantage of Bluetooth 4 (smart bluetooth) is that it consumes very little and that hardly diminishes the autonomy smartphone
The bracelet sends its data when he wants: several times a day but when: mystery! So do not expect to read the same number of steps on the smartphone and on the bracelet when you visit them.
The goal is to know how many steps you walked every hour and have total every 24 hours. And that the application does very well. But it will sometimes wait until tomorrow to see the full histogram of yesterday.
Sleep app is also good with hours of deep and light sleep.
