Hi Developers!
I love Sleep As Android. I have always used it with phone sensors and I feel that sleep tracking is still more accurate by your algos that done by my smartwatch.
So I feel you crunch data better.
Can you add Fireboltt smart watches into the list of wearables? It is an emerging brand in India in low cost range and has big penetration in the Indian market. You have mi band which is great. Please add this one too as I feel this brand is going to make big. Also because I have their Ring 3 model.
