Wondering what the release plan is for Firmware 2.9 and the Oxford Pedometer

i'm upgrading to v2.09 and use another app than activepedom is enought to test the new algorithm?

Yes, absolutely! Just the normal HRM widget is fine: https://banglejs.com/apps/#widpedom

Carried away by my step counting success, I also applied the same ideas to the heart rate calculations. The form of data reported is a bit different so some apps may not work (eg the heart rate app needs tweaking) but the heart rate widget https://banglejs.com/apps/#widhrm should be a good way to test and will hopefully provide faster, more accurate data as well.
