Even though this isn't the place for questions, nor is your question very relevant to coding, the answer is that your bluetooth headset doesn't have an accelerometer in it, and is incapable of counting your steps because of that. So sorry, you would need to keep your phone on you.

I agree with you partially but if the signals of Phone can go and come from Headset using Bluetooth as we can forward to next song, we can receive call or cancel call while listening Music why can't it just calculate steps if there is any movement in a person or headset.
Just think about it, it would be a great idea if someone can do it. I am not looking for exact calculation to have GPS in it, just number of steps and depending upon that calculation of distance, as many other cheap Pedometer Phone apps do within the Phone when Phone was moving.
Just saying as I am a Darwins believer so let me explain in his way , the whole science is born for Human to keep his hands free, from the beginning of the History when Human made his first water bottle using Ostrich Egg. To keep his hands free while carrying Water so that he can act if any other animals attack him or focus on other things while carrying sufficient water for him, for that time that was biggest innovation.

Because neither the phone nor the headset have enough information to calculate steps if the headset doesn't have an accelerometer in it. The only information the phone might have is bluetooth signal strength. Assuming a perfectly non-directional antenna, you could walk around the phone in perfect circles for a day and the signal strength wouldn't change except for battery considerations. The phone wouldn't see you 'move.'

Noom walk pedometer.
Simple, free and works.
Get it from the google play store.

Unless your headset has a pedometer then there isn't an app out there which will magically add the functionality. Be weary of any app which claims the contrary. In theory, if your headset has GPS built in, an app could measure change but I wouldn't trust it for step counts given GPS accuracy.
So it is either carry your phone or start wearing a fitbit/similar then syncing it with your phone.

Most pedometer apps, even cheap ones, utilize the accelerometer built into phones to calculate motion. Most headsets don't have an accelerometer to get information from, some of the newer fitness oriented ones aside.

In theory you could use the Bluetooth signal strength to calculate distance of a device from the phone but that would be very dependent on the environment. It would be a very rough guess at best.

You do get what Bluetooth is right? Its a simple (well relatively), radio transmission and receive standard.
Common sense is admitting there is cause and effect and that you can exert some control over what you understand.

A colleague today asked me to show him the database structure for an application I wrote a couple of years ago, for maintenance purposes. I directed him to the database diagram I had helpfully created in SQL Server.
Sadly, upon opening it, it became apparent that someone had for some unknown reason decided to remove all the relationships between all the tables, for no obvious reason.
I despair sometimes.

Parallel relationships can produce unspecified behaviour.
Especially if the other one finds out.

And therein lies the value of forced auditing, saved outside the environment.
Perhaps a block-chain on changes is needed... unless of course, the change is done from the 'sa' account and multiple people have access to the password.

I've experienced something like that once.
For no reason, quite a few FK's had disappeared...
I'm pretty certain no one on the team did it because we all knew the value of FK's.
To this day I've seen it once and still can't explain it.
My guess is that some external tool (comparer? EF? modeller?) removed them for some reason.

Since "everyone knows it", no one would admit not knowing.

Last week I added a few fields to a table, no problem.
Yesterday we got the data and I realized I needed to change the type of one field in said table as the data was a bit different than I had expected.
No problem I think, we haven't added any data to that field yet, so I enter design mode, change the type and save the changes.
Up comes a popup stating it cannot rewrite the table as there are several tables depending on it.
No problems I think again, I cancel out of it and decide to change the table the next day using DDL instead.
And today to my surprise I see that the table does not have any foreign keys anymore.
Go figure. The takeaway is to not trust the designer mode of SSMS.
<edit>I haven't tested it fully yet, but it seems like it might happen when you have an indexed view on the table

When I have that problem, I rename the column with a suffix of "_DELETE" and create a new column with the old name and newly desired characteristics. The designer will let me do that without dropping and recreating the table. After I have migrated any data and updated any involved stored procedures and entity framework models, I delete the old column.

I simply don't use the designer any more.

I've seen this too, and know the reason. It's not a good reason, but it's a reason.
I'd designed and built a database with full referential integrity.
A team of programmers started to build a system around it.
Every time their code violated the rules, guess what? An exception was triggered! As intended. Imagine that.
It came to time to roll out the project. This meant deploying a fresh copy of the database to a production server. I used the same scripts that I'd written to deploy the development copy.
This resulted in a herd of coders arriving at my desk, all red in the face, and demanding that I use the copy on the development machine. It seems that between them, their understanding of error handling consisted of "on error goto", and they'd been so overwhelmed by the exceptions that the RI in the database caused, they'd removed all of it from the database. Seems my idiot boss saw no harm in giving them admin rights on the database server. Thankfully, he took my side when I explained to him why the project was going to be delayed!
So, if you're surrounded by idiots, then there's a reason why the RI was removed. It's not a good reason, but it's certainly a reason. Namely, you're surrounded by idiots.

How could such software go into production?
It's not correct by definition 
No (acceptance) testing?

It's always the same reason:
Some dimwit tries to insert or delete something and bounces off these foreign key constraints. Instead of adapting the application logic to take the constraints into account, the harebrain throws the constraints (and the database's integrity) out the window.
And what will they say when you ask them which part of 'referential integrity' they did not understand?
(Offended whine): "But it works (*)!"

First job out of college, I was that dimwit Jr Developer. We needed to delete a few items and add a few new ones. You guessed it, I ran into the constraints.
So I asked the Sr. Dev, he said to drop the keys, add and remove the items, then re-add the keys. Being a good student, I followed his advice. At least I was smart enough to use the automated generate Drop/Add script functionality in SQL so I didn't screw it up THAT much.
