Not super useful
This app appears to require users to “tell” others where they are/when they will return. For a society that won’t return shopping carts back to the stall, good luck getting anyone to use this.
Signup link doesn’t work
While signing up, the app complains that I am using a browser and need to continue on my phone. BUT I clicked the link on my phone..
Response from developer
Thank you for reporting and we are sorry for the delayed response here in the comments. We have located the problem and will be releasing a new version in the coming days where this is fixed.
