This is great, but I think saying 'catching up a few months takes an hour when on mobile' is a bit misleading I think. When I scan 1 year worth of transactions it takes me about ~5 minutes on my phone (doing 'local' scanning with Dana). Admittedly we use spent filtering, but that is described in the BIP too so I don't think it's unrealistic to compare it against that benchmark. '5 minutes' isn't *seconds*, but it isn't *hours* either.
