Over the last 6-9 months, I build an app to calculate the optimum jet lag management plan from a combination of flight. It tells you the optimum times for light exposure, sleeping, taking coffee... It started with a naive "I know the tricks, let put them in an app" based on my own travel experience and quickly turned into a pretty nasty constrained optimization problem to optimize a cost function while keeping the schedule realist. So far I have been slowly releasing with friends and family, but I am pretty happy with the results as it can handle pretty complex combination of flights and layovers, compared to other similar apps. If anyone wants to poke at it, I'd love to have some feedback! https://www.jetlagcoach.com https://www.jetlagcoach.com
