Scrolly covers Mac and iPad as a paid add-on, separate from the phone blocking that comes with the tag. Phone blocking carries no recurring fee; the desktop and tablet option is priced separately on the store.
Blocking an app on a phone does not block the same site in a laptop browser. If your work already happens on a laptop, phone-only blocking tends to relocate the habit rather than end it - you stop opening the app and start opening the website, usually within a few days. Anyone who has deleted an app from their phone and then found themselves on the mobile site knows the pattern.
If your laptop is not part of the problem, this add-on is one you can ignore entirely, and the tag on its own covers you.
The same tag governs everything. You are not managing two separate blocks with two separate switches - the tap that unblocks your phone is the tap that unblocks the rest.
Current pricing for the Mac and iPad option is listed on the store. The tag itself is $49.95 once and covers the phone.
