Limited usefulness
I bought this app to figure out when I added a contact. I met someone, went to add their info, but somehow already had it and neither of us knows why. This app only goes back one year on displaying creation dates, (showing some as being more recent than they should be) and modifications appear to reflect software updates, so all my contacts were ‘modified’ the last time I did a major iOS update on my phone a few weeks ago rather than actual data changes.
So if you added a number recently and/or don’t need accurate modification dates, it will work and it’s cheap.
