I’ve gone back and entered most of my dives in Mac-Dive. I’ve added a photo of the original logbook page to each added dive. It is much easier to find things.Another vote for MacDive - I've got the iPhone version which works much better for my Suunto Eon Core than Suunto's own app. That said I keep all my real logs on paper. By "Real" I mean the ones I refer back to. I just like paper for that.
And my collection of DiveOperator stamps would really mess up my iPhone screen
