What I am trying to solve is that when we go throghhiking / multiday hiking, we will carry a lot of stuff in backpack(around 12kg ~15kg). If not pack properly, the backpack will pull back, even worse the muscle will get hurt. Some even have hip bruise.
There are several problem I encounter: 1. lots of forums have policy on banning self promotion, so you can't just post it. 2. even you found someone has similiar problem, ask him nicely and send him the link, he just ignore you and buy a new backpack. 3. for SNS network like twitter / Instgram, the search function seems broken? I found very few posts on it, which I thought should be quite common.
Not sure how to solve this. I can do code but this is not what I am good at. Anyway, its just a prototype, I can throw away and work on something else.

BE WARNED: its a prototype, so its going to be ugly.
