Lifeline: Timeline Map

Lifeline draws the years of ground you have covered from the timeline Google Maps already keeps on your phone. Export it from Google Maps, share it to Lifeline, and the map fills in: everywhere you have been as heat, the day under your finger as a line, flights as arcs across the globe. Then press Play. The marker runs your route at whatever speed you like, the camera leads it, the line grows behind it, and an aircraft or a train carries it where you flew or took the rails. Pick a trip and play only that. Pick a day and see where it went. Trips are found for you: every stretch away from home, named for where you stayed. Places are counted: how often, how long. The strip along the bottom is your whole history, one bar per week. Tap a moment, drag a stretch. Nothing leaves your phone.
