Before you sign up, so you know what you're getting into:
· You need a Google account and an Android phone.
· You'll get an invitation. You have to open it and tap
"Accept" — signing up here isn't enough.
· You install the app from Google Play, using that same account.
· I'm asking you to keep it installed for at least two weeks and
open it now and then. Google measures real usage, and without
that the test doesn't count.
If any of that doesn't work for you, better not to sign up —
and thanks for getting this far anyway.
