A native iOS app that turns “when did this start?” into a question you can actually answer. Timelined is a general-purpose life-event timeline whose unsung killer use case is the personal medical history you wish you had been keeping all along.

The data model is exactly what a timeline needs and nothing more: events with dates (exact, range, or “sometime around”), notes, photos, links, and locations. Events can nest — a trip contains its stops, a diagnosis contains its appointments — and saved filters let you slice the whole record by tag, person, or category without scrolling for it.

The medical use case earns the app its place. A new specialist asks when the back pain started, what tests have already been run, who you saw in 2022. People with chronic conditions or aging parents accumulate a paper trail across years, and the cost of recalling it lives at every appointment. A timeline you’ve been quietly maintaining — even haphazardly — turns the intake form into a quick scroll. Photos of prescription labels and lab PDFs sit next to the date you got them; tags by symptom or provider make the relevant slice surface in seconds.

iPhone and iPad first, Apple silicon Macs as a secondary target. There’s a URL scheme for automation (Shortcuts, scripted captures), but no shared mode for caregivers managing someone else’s history and no FHIR or portal integration. The value is in the discipline of writing things down, not in any clever automation.
