I know Auslan (australian sign language) but yes
https://github.com/SamChenYu/SignSync
Also this one https://chromewebstore.google.com/detail/signup-sign-language-for/gbllbjbhbafgdcolenjhdoabdjjbjoom
I use BSL as it’s closest to Auslan on it but I think they also support ASL and Indian Sign Languave
Thanks for your comments.
How much does the updates thing matter? Good catch on only supporting three years, I’m hoping the phone I buy lasts atleast 5.
