Whats the best ASL app/resource?

[AngelF]

I have a grandparent who was diagnosed deaf last year. I really want to stay in communication with him so am looking to learn ASL sign language. I'm not sure where to start I searched some different apps and found one called Pocket Sign but I don't have an iPhone. I see they have a website https://www.pocketsign.org has anyone ever used it? do you guys have any android/website ASL learning resources to recommend?

Are you going to be learning ASL together or do they have a headstart already?  There are a few ASL dictionaries, like Handspeak, also a lot of material on Youtube.  Google "ASL signs", set it to videos and youtube, and just start watching all the videos.  Take lots of notes to remember the signs.  Open a new notepad file and put in it all the site addresses, you will want to find them later.  look for specific videos on every subject, alphabet, numbers, verbs, time, animals, etc.  Make sure you're all learning the same thing, and make sure you're not learning BSL, wups~
