I am an Openstreetmap enthusiast. I've been using OSM for years, but have only recently started contributing, mainly using StreetComplete, but also with ID. I'm based around FR:Lyon.
I use an Android phone (LG G5) connected by the application Bluetooth GPS to an external Bluetooth GPS : a GloblasatBT-338. This GPS is fairly simple, and doesn't offer much functionalities, but replaces the phone's internal GPS which is notably unreliable (due to poor soldering of the GPS chip apparently.
Softwares
On my phone, I use StreetComplete to improve the map. However, to add or edit features, I also frequently use my computer, with IStreetCompleteD, or less frequently with JOSM.
