New Dexcom G6 user -- can someone define exactly what xDrip+ does?

[Chris]

I am honestly not sure. @docslotnick is our resident expert. Here is a link to one of his posts where he talks about installing it.

New to xdrip, how do I install it?

I recently read about the xdrip app for the dexcom 6 cgm. Everything I read is for using ann apple or android watch with it to view results. Can I somehow use it just on my Samsung galaxy 8+? Can someone please help me and tell me steps to download it and get it working on my phone? Also how I can use the sensors more than 10 days? Thanks to anyone who responds
