During your trial you can run four Room Checks in any seven days. On a paid plan there is no cap and no counter on the screen.
It is rolling, not weekly
There is no reset day. Each check frees up again seven days after you ran it. So if you did the kitchen, the bathroom, and two bedrooms on a Saturday, those four come back the following Saturday.
Four in a week is more than most people need. A typical home has three or four rooms genuinely worth checking, and doing them across two sittings is easier on everyone than marching through the house in one go.
One thing worth knowing
The same limit applies during the grace period after a payment problem, not only during the trial. If you are seeing a counter you did not expect, that is usually why, and sorting the card out clears it.
On the Free plan
Running a new Room Check is a paid feature. Every report you have already run stays readable, forever, at no cost.
That distinction is deliberate. Findings about your own home should not disappear because a subscription lapsed.
The photographs are different
Room Check photos are removed after 90 days on every plan, including paid ones. Upgrading does not extend this.
The report and its findings stay. What you found stays here; the pictures of the inside of your home do not, because the safest place for those is nowhere.
