Well, some of
the metrics that
I mentioned before,
obviously,
we look at
the installed base
of active devices.
We see,
we want to
make sure that,
the customers that
we acquire
remain with us
and so we have
good visibility
over that,
and we pay
a lot of attention
to the behavior
of the installed base,
both by product
and by geography.
And then,
we look at
the daily
engagement
in the ecosystem.
So that's why
we pay
a lot of attention
on things like
transacting accounts,
paid accounts,
we want to see
if,
in fact,
we are able
to move
our customers
from a free model
to a paid model
over time.
That's obvious very,
very important
for us.
