Working solo on few thins:
https://masterlist.fi - shareable todo list without login
https://hockeytactic.com - tactics board for ice-hockey and floorball with live collaboration
This is the biggest marketing effort I've done for those projects in months :)
Like the first one because it's so simple, but you need to add a QR code somewhere: it would make a list more easily shareable. ;-)
