25 days ago Philips wrote about this in another thread: Aurora Store instead of Aptoide At least at that time, they hadn’t made up their minds about which app store to go with. In my opinion, there would be both good and bad things with having a Philips App Store.
On the positive side, it would only contain apps (and versions) that actually work with the projector. Users wouldn’t have to try dead ends themselves so much anymore. On the negative side, as you say the range of apps would probably be more limited than in Aptoide. I can also see the Philips Store being quite dependent on the users being active in requesting and suggesting apps themselves - and thus depending on a large enough active user base.
