update *** developer responded very quickly with reassurance that update is pending. Used very successfully for about 5 years, but this morning logged on and the cards section is not visible, so unable to see any of the details stored. Backup showing as not compatible so, I seem to have lost data, functionality? Not sure how to report this as not seeing any other reports of failure?

Great app. Easy way to store password information without any extra fuss. The password generator is really handy as well. I'm satisfied with the app as it is, but I do have a suggestion. The icon selection for custom categories could use more color options for people that like to organize things with colors. You could just take the gray icon that's used in the "other" category and make it different colors.
