Plan and billing · Add-ons
Where do I buy add-ons?
ComputerBoost in the sidebar (the URL is /boost). It has two panes — Storage and Add-ons.
PhoneOpen Boost in the Menu tab, or Settings, then Plan & billing, then Upgrade & add-ons, which goes to the same page.
Boost is owner-only. Deep links land on a specific add-on, for example /boost?tab=addons#foresight.
