1.0.18

September 3, 2021

Minor improvements and bug fixes.

User reviews

Fun little device and great idea but...

Fun little device and great idea. But virus transmission risk appears to be just a calculation based on humidity and temp. Pm2.5 would give an indication of viruses attached to particles and is obviously a very important pollution measure. Not to have this is a big omission.

App closes when attempting to open map view (v1.0.7)

I’m happy with the new version of the app, except that the app closes when I try to open the map view. Please fix this.
