KeepDates is an iPhone app for tracking important dates stored in contacts. It is aimed at people who want reminders for birthdays and other contact-based dates such as anniversaries, first meetings, graduations, and custom milestones that iOS does not surface on its own.
The app scans the date fields in a user’s contacts and finds dates worth remembering. A user then reviews the detected dates and chooses which ones to keep, and nothing syncs without that approval. Selected dates are turned into recurring calendar events with advance reminders, and KeepDates stays in sync as contacts change over time. It also includes Home Screen widgets that show upcoming dates at a glance on the Home or Lock Screen.
KeepDates is designed for iPhone and is described as fully offline. It runs locally on the device, with no internet connection needed, no account, no email or password, and no tracking. The app says it reads contact dates only, with no analytics, ads, or third-party SDKs, and that contact data never leaves the phone. It is offered free to try.
