@pgiulan For context, I last ran iOS in around 2010.
GrapheneOS has access to the Google Play Store, but Google Play Integrity Check feels targeted to make as many apps as possible fail to run on de-Googled GrapheneOS.
Keep in mind that fully Googled GrapheneOS is possible. I just don't see the point in it. Part of my purpose in moving to GrapheneOs was to not have any single for profit company control a huge portion of my digital identity, anymore.
That said, I use F-Droid, and I find the app ecosystem robust. In 2010, iOS and Google Play we're full of small free ad-free (open source) utility apps and games by passionate hobbyists.
In 2026, F-Droid is the only place I am able to find those apps. When I started using F-Droid, I was delighted to discover where all those small no nonsense productivity apps had gone off to, as I felt they had been missing on Google Play for at least a few years.
Pro-tip: F-Droid works on any Android phone, so you may be able to preview the app ecosystem.
The worst part of F-Droid is the same as Mastodon: there's no algorithm and search can be hit and miss. So I tend to rely on web searches or recommendations on Mastodon to find the best apps.
