SideSpace keeps several separate environments on one iPhone or iPad. Each Space has its own web sessions, its own notes, its own photos, and its own lock. TWO ACCOUNTS, ONE PHONE Sign in to the same service twice — one account in your Work Space, another in Personal — and the two never see each other. Each Space keeps its own cookies and its own sign-ins, so switching Space switches everything at once. No signing out, no re-entering passwords. WHAT LIVES IN A SPACE • Web apps you pin, each opening straight to the service 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 • A camera that saves directly into the Space it was opened from PRIVATE SPACES A Space can be marked Private. Private Spaces are not listed at all until you unlock them — their names stay hidden, not just their contents, so handing someone your phone does not show them what you keep separate. Unlock with Face ID, or with a passcode that is separate from your device's own code. YOUR DATA STAYS ON YOUR PHONE There is no account to create and no server to sync to. Everything a Space holds is stored on your device. Export a backup to a file whenever you want one. STARTS WITH SOMETHING USEFUL Pick what a Space is for — work, selling, studying, creating — and it arrives with the apps that usually go with it. You see the full list and approve it before anything is created. A PROXY PER SPACE Spaces already keep separate logins, but they share one connection. Point a Space at your own proxy and its web traffic leaves by its own route, while your other Spaces are untouched. You bring the proxy — SideSpace runs no servers and sells no bandwidth. A NOTE ON WHAT THIS IS 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. Web sign-ins are not included in backups, and web push notifications are not available in a web session — if you need alerts from a service, keep its own app installed alongside. SideSpace Premium unlocks unlimited Spaces, private Spaces, and ad blocking.

Verdict

EmailOnDeck's advantage is iOS requirement (15.1 vs 17.0). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
