Keepspan: Life Interval Log

When did you last replace the filter, visit the dentist, service the car, give pet medication, or call someone important? Keepspan is a private event tracker for things that do not belong on a fixed calendar. Record an event once and the app preserves exactly when it happened, its complete history, and the interval since the previous record.
