OS Dynamo Customer Insights

1. it think because it doesn't have a gps adn it is probably set on standard walk speed (6/7km/h), anyway it is good if you walk to your job, walk home etc but if you use it for your serious sport activity, forget it.could use a prettier UI and more info, but all in all it does what it's suppose to (the only problem is that the calorie counter is way off).

2. Still does this everytime! Won't let you change your weight unless you choose imperial meausurments.Sleep monitor got the start time right, but that is all.

3. Apart from last night, when I put it into sleep mode at 00:17 (after midnight) and it got the scaling correct - but plotted it for tonight rather than last night.

4. But please fix following: sleep graph not display correctly if you go to sleep before midnight, cant set distsnce milestone, viewing distance record crashes app.

5. Even time turning off sleep monitoring is wrong.Tried on android and iOS and neither update to mapmyfitness.

6. landscape mode in "records" menu is a nice touch too, for viewing details about past recordings.Device is pretty inaccurate, don't think it is the app's fault, thought.

7. Times asleep & awake completely off--I can be up, walking and even running stairs for hours and it records as sleep.

8. The graph scaling could have more detail.I synced it to my phone and it automatically said I walked over 1,000 steps and burned over 3,000 calories.

9. I am currently also using the older activity band app as it does plot the data correctly even if it is buggy in other ways.

10. Going to buy a different brand and toss this one if a fix doesn't come soon.Doesn't let u change the weight from 44 lbs.

11. So many things wrong with this app.Only tested this device and app for an hour and apparently I burnt over 3000 calories! Taking this pile of crap back to the store.
