Walked away and forgot to lock your Mac? Lock Notify sends a notification to your phone whenever your Mac is left unlocked and idle. Tap "Lock" right on the notification and your Mac locks instantly. Every lock is verified, and you are told the real result. HOW IT WORKS Install the free Mac companion app (macOS 13 or later), scan the QR code on your Mac's screen with your phone, and you're done. No account needed. The pairing code is stored only on your own devices. FEATURES • Left-unlocked alert: a notification when your Mac is awake and idle • One-tap remote lock, verified every time • Live status: battery, model, locked or not, Work Mode on or off • Wrong-password alert: instant notice when someone tries a wrong password on the lock screen • Bluetooth proximity radar: see your distance to the Mac and lock automatically when you walk away • Café Mode: full-screen theft alarm if the charger is pulled, the lid is closed, or someone touches the Mac • Work Mode: keep your Mac awake, toggled from your phone • Scheduled end-of-day lock • Quiet hours • Activity log and weekly security report • Apple Watch app and home-screen widget: lock from your wrist or with one tap • Available in English, Turkish, German, French, Spanish, Russian, Chinese and Japanese PRO (one-time purchase) • Unlimited Macs (free tier: 1) • Intruder photo: a front-camera frame attached to the wrong-password alert* • Remote alarm and remote sleep • Auto-lock when you leave a safe zone (location) • Multi-Mac widget, full history and security report PRIVACY No account, no ads, no analytics. The command channel is end-to-end encrypted; the server only sees an opaque envelope. Location and photo processing stay on your devices. The only data shared is an anonymous push token used to deliver notifications. SECURITY NOTE Locking is one-way: your phone can only lock your Mac. There is no remote unlock. * Wrong-password detection and intruder photo work on the macOS versions supported by the Mac app; they are not available on macOS 26 and later in the Mac App Store version.

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. • Yearly — $19.99 per year • Monthly — $5.99 per month • Weekly — $2.99 per week • Lifetime — $39.99, one-time purchase (not a subscription) Try every Premium feature free for 24 hours, once: no subscription, nothing charged. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Payment is charged to your Apple Account at confirmation of purchase.
