About SideSpace

Last updated Oct 19, 2026

SideSpace keeps separate Spaces on one iPhone — each with its own web sessions, notes, photos and lock — so the same service can stay signed in as a different person in each, and switching Space switches every account at once. It runs services in isolated web sessions; it does not clone or modify any app, and it is not affiliated with any service you add.

The guides on this site answer the questions people ask about several accounts on one iPhone — two of the same app, work and personal, Safari profiles, privacy — and put the free, built-in option first, whether or not you use SideSpace.

Who makes it

SideSpace and these guides are made by Sang Cao, at Sang Cao Labs, who designs, builds and supports the app. Every support email is answered by the person who wrote the code.
