Blotpath

The city is your canvas. Walk a street. Leave a line. Come back before it fades. Blotpath paints the routes you actually run or ride. Phone in a pocket is enough. Ink stays for about ten days, then the canvas forgets — unless you walk it again. You never pay to stop fade. Apple Watch can start the same walk from your wrist, even with the wrist down. Party is optional. Friends join with a code and share finished walks on one neighborhood canvas. There is no live map pin, no ads, and no stranger feed. Location is used only during an active walk. Ending the walk stops it.
