I searched many places for address book that suits my needs but cannot find such one (or cannot use what I found)
I meet many people in many cities and organize many different events on demand. Like please, give me 10 people that can help me with music performance in Berlin - it's where I call people that lives in Berlin and has some connection with music. Or need to learn bridge here and there or My washing machine doesn't work, do you know who can fix it?
At the moment, my contacts are a mess, I cannot filter them easily and miss a lot of people because of that. I cannot check my contact list again and again. That's why I need some help.
The most crucial part is I need to have the possibility of creating categories with tags, tagging people, and filtering them by that. It would be nice to have it somewhere in the cloud so I could edit tags with my PC. I will use that in two places:
My Android phone - to quickly filter people that match the multiple tags (like Warsaw, Dance, Girl) and be able to call them.
My PC - to use with an email client (using neomutt) and easily send emails to some subset of people.
I am fine with paid solutions, I am fine with creating such an address book from scratch I just need to find a way to manage a huge list of contacts in both places. I could prepare my own scripts for PC but have no idea what kind of software and format I could use on Android.
