Accrescent, for those who don’t know, is an alternative android app store. They aim to compete directly with the play store, so unlike F-Droid they include both FOSS and proprietary apps. They are also very security focused. They’re still small but I find their approach interesting and their ambition worth supporting.
Unfortunately, as with many FOSS projects, funding is a challenge. If you believe they are worth supporting, please read this blog post.
Disclaimer: I’m not affiliated with the project in any way, just a fan trying to raise awareness.
You are not the only person unhappy about this. A few people have asked for alternative payment options and they said they would look into it but nothing so far. I’ll give them another nudge.
