Hey PH!
I wrote this no-log-in, one-button app to remove some of the friction around meeting up with people in professional settings. It turned out to smooth out the experience for them as well, and after using it for the past few years myself I'm opening it up.
The entire app is two screens, and it lets you create single-use maps that follow you for one hour and share them with anyone on any device.
That's it! Happy to answer any questions.
