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!
