I heard there was a tablet version of Airbus FCOM, but never saw it. I am back using company manuals, but we just switched to a straight Boeing QRH.
Airbus QRH was OK. I would rate it as just average. A bit of jumping around, especially doing the landing distance procedure.
An example of the Boeing QRH is the "Landing with one engine inoperative". A bit wordy, but the procedure is brilliant. Once you start it you never turn go anywhere else in any book. It even includes an Approach Descent checklist and Landing checklist, made for the single engine condition. Awesome.
