Re: grapheneOS app store - how to get a list of available apps ?

Theo,

I don't think there's anything special about TTS, it's just a regular
app?
In which case this is a general app store question?

Not quite.  Some of the ones I found (using DDG) install but won't work.
Others install and their own testing of the voice works, but I can't get
them to read something from an epub app I installed out loud (and there does
not seem to be an build-into-the-OS method to test for compatibility :-( ).

The only one I found that worked was a Google TTS, which I don't like and
would like to get rid of (Google/Alphabet is an advertising company, and I
don't trust (understatement) their apps to honor my wish for privacy).

The GOS store (the Apps app) only contains OS components from the
GOS developers, so it only has 12 apps.  One of those is the
Accrescent store which is new and that only has a few dozen more.

Ah, that explains why I only saw a handfull of apps mentioned in GOS
appstore-app.

Some options, most of which need sideloading:

Sideloading isn't a problem. In fact, I prefer it as it allows me to both
backup the app on my 'puter, as wel as enabeling me to inspect its
requested/required permissions before I even try to install them.

Google Play Store (installable from the GOS Apps app):
requires Play Services and Google account

:-) Absolutily not.  I have chosen to replace Googles android OS with
GrapheneOS for a reason.

Aurora Store: access to the Play app catalogue but without a
Google account. Individual apps may need Play Services but
Aurora doesn't.

It could not hurt to take on their website and see what they have to offer..

F-droid or alternative fronted (Droid-ify etc): a catalogue of FOSS
apps the F-droid servers compiled themselves

Thats where I got most of the TTS apps I tested from.

IzzyOnDroid: another catalogue of FOSS apps

I do not know that one.  Will take a peek.

Obtainium: installs/upgrades apps sourced from their individual
Github releases (no catalogue, you have to supply URLs)

Hmmm... How would I obtain (no pun intended :-) ) those URLs ?   Is there a
website (you know of) that functions as its catalogue ?

Thanks for the suggestions.
