When used with an iPhone 5S connectivity and data exchange is very easy. You really get away to lose the contact between phone and bracelet (staying in the same apartment, even in another room it works within close all doors!). The notification displays functions of accounts not work without any problem! The screen is pleasant to use (although there are only 2 lines and displays in black and white!) And quite responsive. This is namely the only band to date that allows you to have notifications from an iPhone in any case before the Apple watch! Very surprisingly no other product of this type exists for the Apple brand! Now the bad points: the bracelet itself in â little in my opinion. It is rather the criticism in the associated application! - The legibility of the number of steps depending on the time (to know when it has been most active) as a histogram is not good - Sleep graph is very very bad and very representative of reality. In this case I use an application (Sleep Cycle) for years and it gives a picture of the night even more precise and easier to understand. - No statistics either on the march or on sleep ... - Absolute disaster and nothing works in the application if you do not have any Internet connection !!! It is completely incomprehensible! Finally the system is the job of pure measure: number of steps / distance traveled, number of hours slept, notification. But the application that should do the integration work, processing information for fun and improve your daily rendres does nothing concretely useful ... shame!
