Show HN: I got tired of travel spreadsheets so I made a travel planner app 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. I've tried to make it mobile-friendly but travel planning is pretty complicated and it's a bit clunky on mobile. Feedback is appreciated! https://www.wherewhen.cc October 29, 2026 at 07:37AM
