#Holos differs fundamentally from #Fedilab. As the server runs on your phone, using Holos across multiple devices is currently not possible. The relay caches pending activities and clears them once retrieved (multi-device sync not yet implemented). Traditional apps rely on a server API and are limited to what that server knows. Holos fetches data directly via ActivityPub, giving you access to the full Fediverse.
