I have got done with the conceptualisation. I have tons of experience on electronics and my partner is taking care of the design .. I am seeking advice on what to take care of to ensure the best user experience.
Answering the question "Why do you think users will prefer your fitness tracker over the several in the market?" will lead you to the UX answer you are seeking.
First, I recommend you start by asking a different question. We too often want to get to the solution without fulling understanding the problem. Ask yourself (and your target customer) what job does someone hire a fitness tracker (or other related solutions) for? What are the unmet needs of those users? Does your passion and competence put you in the best position to fulfill some or all of those unmet needs. Be curious and empathetic. Fall in love with the problem and the customer, NOT the idea or the solution. I have many posts on my site talking about this very subject. Here is one that may be applicable - https://catalystgrowthadvisors.com/2017/02/27/7-rules-of-customer-development-interviews/
Since you already have electronics and design taken care of, I'd suggest that you think about the 'larger' role and the 'real' impact your device will have on the wearers.
Your user will wear the device all the time (that is what you'd be hoping for too, I guess). And therefore, it should impact the user's well being in a positive manner. And that's how you should measure your success - was your device able to help the user meet their end goals and objectives.
I recently wrote about something on those lines - check it out here
As for the fitness trackers, I can suggest using most simple solutions everywhere - this is the key factor while developing any sports sensor device.
1) First of all the product and its enclosure should be very comfortable to wear and handy at each side/shape. Nothing should interfere and at somehow prevent doing sport - the device was intended for. The user should be focused on the game, their results and the emotions that he receives at this time.
2) The device management also must be as convenient as possible. Navigation should be realized by capacitive touch sensors, soft buttons in right(comfortable) places or by voice.
At Space-O the last 10 years we are developing custom smart-sensor devices and IoT solutions with related Mobile/Web apps for them - so we know almost everything about them, from PCB and Firmware to manufacturing.
Here are few of them:
• Ezepark: http://bit.ly/2wor69x - solution for total automation of the paid parking lots (Short video from the real field testing: http://bit.ly/2CJp7Pm)
• Shot Stats: http://www.shot-stats.com/ - smart sensor solution for the Big tennis
• Syrmo: http://syrmo.com/ - tracking device and apps for the Professional skaters
That's why we will be happy to provide you with absolutely Free consultancies on any other questions which might appear in the future.

One of the best-known books on UX is called "Don't Make Me Think!" The title says it all. If a user has to spend any time figuring out what your app does and how to use it, you've probably lost a customer.
Test with real users as soon as possible, even when you are still at the wireframe or paper mockup stage. Any problems with assumptions you catch early are good, compared to taking those into your hw stage.
I have used and enjoyed several trackers ( i tracked everything from breath, posture, steps, brain waves etc etc) in the past and currently use none.
1) Its a chore to charge them and use them consistently
2) I sometimes forget to remove them and throw them in the laundry
If you are developing a new product, I would suggest you design it to tag on to an existing product on the body , Like a watch instead of new straps or new parts ( its very difficult to change habits in this area)
This may be unsolicited advice. But I am in direct contact with the directors of innovation and strategy for hospitals across the nation. And they would love for a company like yours to work directly with them to develop health/fitness trackers based on their critical needs and priorities that will lead to better patient treatment and outcomes. Someone I might suggest reaching out to is Cintrifuse in Cincinnatti, Ohio. They are a startup accelerator, have a fund, and act as a matchmaking service with potential large suitors as well as hospitals. Look at my recent interview with the head of strategy for Mercy Health, which works directly with Cintrifuse! They are seriously looking at ioT: http://vator.tv/news/2020-03-03-meet-david-cannady-chief-strategy-officer-of-mercy-health
How do you know these "unique features" are of any value to any potential customers or users?
That's about the most basic UX question you can answer. And how you answer it is critical (that is, "my friends like it" or "there isn't anything like it on the market" is not a good answer).
There have been lots of great answers so far. But my most important advice to you is to validate your ideas with actual users. And then test and revalidate often.
While at my last startup, this real-world user testing was invaluable, especially since we were working in a new medium (VR). Because we went to a lot of conferences, we ended up demoing our product to hundreds of people around the work. That gave us great insight into the usability of our product, but also its utility and what people were wanting from a product like ours.
