One phone. Multiple spaces.
SideSpace: Multiple Accounts
iOS keeps one signed-in session per website. If you have two accounts on the same service — a personal one and a work one, two shops, two of anything — you sign out and back in all day, or you use private browsing and lose the session every time you close the tab. Android answers this with dual apps and work profiles; iPhone has neither, and Safari profiles go only part of the way.
How to use multiple accounts on one iPhone covers every option, with SideSpace and without it, and the guides further down take it service by service.
SideSpace gives you several separate environments on one iPhone instead. Each Space has its own web sessions, its own notes, its own photos, and its own lock.
It reached the App Store on 8 September 2026. iPhone only, iOS 17 and later.
What a Space holds
- Web sessions. Cookies and sign-ins belong to the Space, so switching Space switches every account at once. No signing out, no re-entering passwords.
- Pinned services, each opening straight to the account you signed into in that Space.
- A browser for everything else, with its own tabs and history.
- Notes.
- Photos and videos, kept inside the Space and never added to your Photos library, plus a camera that saves straight into whichever Space it was opened from.

Private Spaces
A Space can be marked Private. Private Spaces are not listed at all until you unlock them — the names stay hidden, not only the contents — so handing someone your unlocked phone does not show them what you keep separate. Unlock with Face ID, or with a passcode separate from your iPhone’s own.
A proxy per Space
Spaces keep separate logins but share one connection. Point a Space at your own proxy and its web traffic leaves by its own route while the other Spaces are untouched.
You bring the proxy. SideSpace runs no servers and sells no bandwidth.
Your data stays on the phone
There is no account to create and no server to sync to. Everything a Space holds is stored on the device, and you can export a backup to a file whenever you want one.
What this is not
SideSpace runs services in isolated web sessions. It does not clone or modify any app, and it is not affiliated with, endorsed by or sponsored by any service you add to a Space.
Two honest limits that follow from that: web sign-ins are not included in a backup, and web push notifications are not available in a web session. If you need alerts from a service, keep its own app installed alongside.
