Wow. Was the format reverse-engineered? Because MAPS.ME a closed-source app, right? Please do tell the details! 
This guy has some relation to company-developer of this application. Maybe he is working there. I do not know details. Looks like he is very smart guy.
Oh. So I will tell him some of my suggestions about maps.me, as it’s one of the best (or, least crappy) OSM apps. You know, it’s good overall, but some annoying details make for a sloppy experience. There’s a huge gap between good and perfect
IMHO it is better to send email to maps.me support. However support is not so responsive as would like to be.
