Can you restore an iPhone app in Safari?
A normal website cannot inspect all apps installed on iOS or install arbitrary App Store IPA files. The direct Safari installation pathway is not yet part of the public RestoreDesk service.
What the current browser page offers
Information about purchased apps, a public App Store catalog lookup, and an indicative price calculator. The site does not request Apple Account passwords, two-factor codes or card details.
What needs technical verification
Apple authorization, proof of licence, selection of an available IPA version, supported installation delivery and restoration of the original app data. None of these can be assumed from a competitor screenshot.
Safer first steps
Check five restoration methods, beginning with your App Store purchase history. Do not delete an existing placeholder or a working app before preserving your data.
