Some relevant comments from the developer on another forum from about a year ago, when they only had 10 apps:
Developer of Accrescent here. Yes, there are only a handful of apps available right now. The reason for this is that the recent focus hasn’t been directed on getting more apps in the store, but instead on internal changes to allow Accrescent to include more features and scale to more users. It will be able to include more apps once more of those changes are implemented.
Yes, we may take on some additional apps over time. This depends on how much the project can handle maintenance-wise and how willing those app developers are to deal with the early and changing nature of Accrescent. We’re not directly reaching out to any developers at this time, however.
So apparently it’s been a deliberate choice so far.
My understanding is that the whole point to trying to hire a full time developer is to be able to finally scale their services.
Yay, some success :D
The squabbling is, ugh, ¯\_(ツ)_/¯ Everyone agrees that the current duopoly of apple and google app stores is bad, but instead of supporting a variety of alternative options, they expect every option to offer a perfect solution for whatever they’re a purist about.
