Its very good for an app, IMO. I think it would be disappointing on a PC (nowhere near the depth or breadth of something like Mass Effect). Its got about 12 hours of play in it, limited replayability (mostly because you can do everything from decking to rigging to magic and pretty much everything else with 2 maybe three play throughs.
It still has a few bugs (especially with regards to summons and drones). But it has that highly customizable character development combined with a world that lets you worry about how summons interact with drones. The story line is very linear but solid.
You have over 200 karma points by the end of the game (I had 235) so you can develop a couple of archetypes.
