The Rode recording app solves all my issues, though it requires some extra work. You can select sampling rate and stereo or mono file before starting to record, when you finish and want to export you select the export format (.wav, mp3, FLAC, etc.). For a shorter file I selected wav and got a true 96kHz wav file. I then recorded for about three hours, it didn't do a split but for export there was no wav selection available, only CAF. Audacity will allow you to load the large CAF file and split it to export as a 32 bit floating wav file, Wavelab and iZotope Rx can handle those. The transfer to PC is either by WiFi or iTunes, WiFi can be rather slow but otherwise I've had no problems.
Hope to try it out in the field next week.
