Find the time when to meet. Offer a few days and times, share one link - people tap what works and the best slot rises to the top.
No sign-ups, no app. People open the link and tap what works. Ask which days work, or get specific with time slots. Timezones supported. The three most popular slots stay highlighted. Darkest wins.

The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
