I bought and used Quiver, but I'm slightly concerned about the lack of (frequent) updates. With many apps this is not much of a concern for me, but if I'm going to store much of my data in one, it does matter. As such, I've been, once again, working on moving away from this app into something more basic/generic to avoid lock-in. FWIW, my needs/paranoia might not be relevant to others, and FWIW Quiver is a nifty app. Still, I do wish I can save others the trouble I went through to get my stuff into this app and then getting it out of that. And FWIW, the storage format is quite amenable to export if you're comfortable with programming, so that's a definite plus for Quiver. (I had issues with the search functionality, and that was enough for me to move away)
