Looks great, especially for a weekend's work. But I think that is a classical example of going too far with the minimum viable product concept.
I would never let you have offline access. I think that quite a few others might not as well. So you might have a great idea but without that feature you might not have a mvp and your trial run will give you misleading data.
Thanks, and you have a good point about offline access; I'm honestly not sure about how big a gamble this is. The thing is, I've noticed that whilst a lot of people who work in IT are completely against the idea (myself included, to be perfectly honest), it seems that there are also lots of people who plainly - for want of a better term - don't give a damn.
My rough plan is to give it a week, and if I don't get even a couple of sign ins by then, spend the weekend sorting out session fun. If you like, I can reply to your comment with an update? :)
