Amazfit Stratos Vs Actifit App Steps Counter, Second Comparison
This afternoon I've published a short article with my first try at comparing two activity / steps measurement approaches. Read all about it in the Amazfit Stratos Vs Actifit App Steps Counter, First Comparison.
With this article, I will show you the results of my second walking comparison attempt.
In between, I've also done a 10K run with both devices active. This report requires more time so I will produce in the near future.
OK, let's jump straight into the second test.
The Devices Compared
Amazfit Stratos sports watch manufactured by Huami with its corresponding Andriod app
vs
Actifit Android app produced by the 
@actifit team
The Environment
A short doggy evening walk with:
- Amazfit watch on my left wrist and my left hand tucked into the pocket 99% of the time
- Actifit app turned on on my phone which I tucked into my back jeans pocket
Both devices were in fairly static position. Intentionally so.
Before
In line with the
After
These are the cumulative steps immediately after the walk ended.
Results
| Amazfit | Actifit | ratio |
|---|---|---|
| 1,029 steps | 680 steps | 1.51 |
This afternoon the ratio was 1.17.
Well, I am surprised. I expected a closer match. Yet, it ended with even a bigger difference than with the first test.
Why?
Conclusion
My guess would be that a phone in your trousers' pocket isn't moving enough for the kinetic sensor and / or the software to count it as a movement and as a step.
With Amazfit app I can easily generate 'steps' by simply shaking the phone on its front / back plane and produce a myriad of steps.
Yet, when it is safely tucked someplace it doesn't move enough in the right direction and back to produce a step.
This concept needs some more work...
Other thoughts
There once was a project called Bitwalking. It was in alpha for a long time with a working app which did count steps and convert them into tokens. These days the project seems to be rebranded as Bitwalk.
I am on their list yet waiting on the invite in vain for quite some time ...
Nevertheless, it is great to see projects like Actifit trying to build a bridge between physical exercise and crypto world. In the process they are also building a community and promoting a healthy lifestyle which is excellent.
Good luck with your project, team
Ps: mentioning again
