When I had a Kindle Fire, I obtained GForth from two different 3rd-party app stores. I don't clearly remember their names. (The're not in my Amazon list.) I think the orange-themed store was called AppSpot. I didn't like its high volume of notifications or the store app itself, but it had GForth regularly updated. The better app store (green theme) didn't update GForth so regularly.
I don't really like to bother with 3rd-party app stores. I'm not good at finding out about what the app store managers are like or who [re]publishes apps on them, so they make me nervous. I'd prefer to download the apk directly from gforth.org.
