Hey everyone! I couldn't find an app to organize trips that gave me all the info I wanted to schedule each stop per day, with travel times, leeway, etc, so I made Wherewhen. The basic differentiator is that you can set various constraints (e.g. "I want to spend 2 hours in the park", or "I have a dinner reservation at 6"), and Wherewhen will automatically adjust the rest of the times to tell you when to go/leave each place, including travel.

From its Hacker News post

Wherewhen is a launch on Show HN.
