Agree with above - Logten Pro and Mobile on iPhone work extremely well. Problems I have had were solved by Noah very quickly. Anyone starting out, military or civil, this is great because you can record anything you want which is such a help filling in those resumes later! Things I wish I had recorded from starting out:
Hoisting/winching
Load lifting
Mountain flying
A friend's logbook was a great thing - loads of photos, paper cuttings etc. Easy to do electronically now...
