The iOS app has just been updated and the firmware of the wristband, it hardly done better in terms of autonomy with ten notifications a day he held only 3 days. Since updating firmware 2.1.40, 2.1.37 of the December 25, 2014 did not improve this, by cons you now have the information from the local weather displayed on the bracelet (min and max temperature and the trend rain etc ...) the display lights up every sudden movement of the forearm strike and that the autonomy of the unit and that's a shame you will have to monitor its burden under penalty of losing your data unsynchronized (I have no low battery notification). I hope Striiv will go back and optimize its firmware ... trump bracelet resident for much of its autonomy!
Yet the very large number of update are a guarantee of seriousness on the part of the brand, it's really scary.
Bracelet very interesting for its features that is not found necessarily in competition, I have enjoyed The display of the notification and the vibration sensor in case Appeals telephone, reception of a SMS or if an application sends a notification (a podcast episode available ) the information is easy to read (as text emoticons are not shown) to read directly on lafficheur you can only receive such notice and in no case to answer since the tracker. This really latout this tracker dactivité if you compare it to the Pulse Ox Withinks for example.
The sensor in a monochrome OLED screen that offers via an intuitive interface to see the different parameters (hour, day / month, the number of steps, distance, calories burned, time dactivité, switching to sleep mode) the autonomy a Once loaded is 5 days (i tested and it's a real autonomy) if you receive a lot of notifications I think he held a little less, but it's already a beautiful performance that perfectly suited my after more than a week of test and measurement.
Tracker side having an iPhone 5 I havent had any problems with The application dedicated to the passage that seems less complete than Withinks which today has an excellent ecosystem connected between its scales, blood pressure all that compatible with "Health" The application appeared with Apple IOS 8 that does not offer the day I write this comment with Strivv is dactivité tracker. Going back to The application I personally find totally ridiculous and polluting the addition of a built-in game that night really readability ALL OPERATING one has the feeling to have a IAd advertising constantly under the eyes, in Withinks side really better.
In daily use'm disappointed with the relevance of the measures quoffre this tracker on several races he consistently failed me several kilometers (15 to 25% less) this is huge for a more accurate measurement i changed the stride length and placed in a tracker pocket along the body (not the tracker nayant clamp system to the place other than on the wrist!) This is in my opinion the most negative point about this system.
By cons, once placed the measures are consistent with my Smartphone and GPS distances measured by it, even if The application is compatible with RunKeeper I have not managed to gain some weird thing remaining to do with next update .
As the tracker can not stand quau wrist, i still had to withdraw after 3 days (a few hours) my wrist is a little irritated (nothing serious), but 24/24 wear'm not really accustomed.
I appreciated the notification warn you that you need to recharge, for cons I do not find the charging system very suitable (you must pinch the tracker in the box for charging)
Sleep measurements are blurry and poorly expressed, the measures are there but this is virtually unusable too small and not cut by time slot (can do better on this side).
For: build quality, the autonomy, notifications, for leaks in the shower, OLED screen.
Cons: can be used quen bracelet, the measures lack of precision in the sun it may be hard to read the screen, the loading system, ridicule reward game.
Conclusion: Although the finish is at the rendezvous I deplore the lack of versatility of this tracker a unique bracelet does not suit me especially when the measures that it generates are false Withinks the Ox will be much better dailleurs bracelet mode, but makes up cleverly by the clamp which allows that it offers to keep him closer to the body for a more refined measurement of distance traveled. The games offered 8 The application IOS only pollute it and actually irrelevant (in my case) damage is yet complete and have just been updated (17/10/14) announced the autonomy is real but it is impossible to change the battery by the user (as many tracker matter). Notifications are the real asset in my opinion of this product and the element is that it must take into account when buying running and be notified directly on the tracker this is the top! by cons if you want a more versatile and probably more accurate tracker Withinks done better in this area.
