@Ladygz I’m lovin’ the attitude, can’t fault it in the slightest I couldn’t agree more, Sweatcoin is a fantastic way to motivate users to adopt a more active lifestyle. It’s great to see an app that reaches out to such a diverse array of users and has something in it for everyone. Awesome outlook, but leaves a question that it would just feel wrong not to ask… Why specifically 104?
With regard to a lanyard for your mobile… there are many different kinds of phone bags, cases, pouches etc. Amazon stocks a wide Variety of suitable products. For example https://www.amazon.com/Go-Bag-Self-Sealing-Waterproof-Touchscreen/dp/B075MLKWXB.
I hope that helps to at least give you an idea of the kind of products on the market
