Hyperdrive (and the stack it's built on more generally) works great offline. All the drives you own are still editable without the network, and changes will sync when you come online.
As for 'network questionable' and mobile, here are a few of the other projects building on Hypercore that have made those a priority [0] [1] [2].
The Hyperdrive daemon as it's currently built wouldn't fare too well in a bandwidth and/or battery constrained environment (wasn't designed for that), but a mobile solution is definitely on our radar.
