Do you have any hacky ideas that we can do to help with quarantine?

Here is mine : Nearly everyone has a smart phone running iOS or Android (with FB, WhatsApp, Instagram, Chrome, etc... installed). If these devices/apps could: (1) Regularly track location data (2) Regularly ask users for their symptoms.

I want to know some hacky/clever/creative real life ideas so we can help, remembers that hackers are 1 % helping the 99 % .
