The primary metric that the Lumo Lift app used was a 'good posture hour,' which was defined as an hour in which someone maintained good posture for at least 40% of the hour.

This would give more motivation to those who are starting out and struggle with reaching the targeted 40% good posture in an hour, and it would also offer those who consistently exceed the target a way to quantify their achievements (distinguishing between 40% and 99% of the hour). Solution: Another more intuitive metric for tracking posture could be introduced, such as a count of the total number of minutes of good posture, the longest string of continuous good posture, number of buzzes per hour, etc. I would like to see more minute-to-minute data to stay motivated.” (Appendix) Swell, but five hours compared to what? Did I only wear the thing for five hours, or did I use it for sixteen hours?” Another lamented that it records 0 hours if one is below the 40% goal line: “I love the concept of the device but only seeing zero hours of good posture despite having the coach turned on is discouraging.

One pointed out the lack of context: “…it will tell you '5 hours of good posture'.

In addition, good posture for 40% and 99% of the hour were both recorded the same way, as 1 good posture hour.Īll 3 testers remarked that the good posture hour metric could be improved: (1) “posture hours is a bit ambiguous ” (2) “it’s not a very intuitive metric ” (3) it’s “just the total, I want something more granular.' 4 customer reviews expressed frustration at the use of “good posture hours” as a metric. That means that somebody could reach 39% good posture for 12 hours, but still have 0 good posture hours. An hour was classified as a 'good posture hour' when the user had good posture for at least 40% of the hour.
