Inaccurate counts

[JTION]

I have used numerous trackers over the past few years and am disappointed in the Ionic because it is relatively inaccurate (compared to other devices I've used). Counts for steps are off by 10-15%, stairs by 25-50%, sleep time by 30-40%, pulse rate by 10-20%. The O2 sensor is nowhere to be found (a primary reason I purchased this large and expensive device. Hopefully there will be some software/firmware updates to improve the device soon or I will put it in the drawer and return to Garmin.

Hey there @JTION, it's nice to see you around the forums!  I'm sorry to hear about the discrepancy you're seeing between the trackers. 

The algorithms used in Fitbit devices are the same, so you should see no more than a standard 4% variation between them. It's possible to get different readings if the trackers are worn in different locations (dominant vs non-dominant wrist). I'd recommend reviewing the accuracy information provided in this post. 

Once you've reviewed it, please try this step accuracy test:

1. Put your wrist-based tracker on your wrist or put your clip-on tracker on your hip or torso.
2. Walk 100 steps, making sure to count a step each time one of your feet hits the ground.
3. Pause, then check your tracker to see your step count.

On the other hand, in regards to the floors counting, your tracker registers a floor when it detects continuous motion combined with an elevation gain of about 10 feet. Because the tracker looks for continuous motion, pausing too long when going up a flight of stairs can cause the tracker to not count the floor. 

10 feet is an average between residential and commercial floor heights. If the floors you're climbing are shorter than 10 feet, you may find that the Fitbit tracker's floor count doesn't exactly match how many floors you've gone up. For example, if you climb 3 floors that are 8 feet tall (for a total gain of 24 feet), then the Fitbit tracker might only tell you 2 floors because it assumes that each floor is 10 feet tall and this is what happens to my at my granny's home. 

Another cause of inaccurate floors is moisture. Have you checked that already? For example, the pathway to the altimeter on the back of your tracker can become clogged temporarily with sweat. 

I'll be around if you need further help!
