But to be honest part of the motivation for building this is because I didn’t want to stay walled in to the Apple ecosystem – I want to be able to access my photos from multiple devices, not just Apple ones. So an Android client, if there’s enough interest (and indeed, there does seem to be) is on the roadmap. Do add your email (alias) if you’re interested :)
