Freezer: App Blocker & Focus

Nova byte

About this app

Freeze the apps that drain your focus, your data, and your battery — without uninstalling them.

Freezer is a free app blocker and no-root firewall in one. "Freeze" any app and Freezer instantly cuts off its internet access and silences its notifications. Thaw it whenever you want and everything is back to normal. No root. No account. No traffic ever leaves your phone.

★ WHAT FREEZER DOES
• Freeze any app in one tap — its internet is blocked instantly
• Silence notifications from frozen apps until you thaw them
• Block background data so apps can't phone home (great for saving mobile data)
• Reclaim your focus by freezing distracting and social apps on demand
• Thaw instantly — freezing never deletes or force-stops your apps

★ FOCUS & DIGITAL DETOX
• Profiles like Work, Sleep and Focus — freeze a whole set of apps in one tap
• Schedules — apps freeze and thaw themselves at the times and days you choose
• Auto-freeze apps after they go to the background (optional)
• A calmer phone, less doomscrolling, more screen-time control

★ SAVE DATA & BATTERY
• Stop chosen apps from using mobile data in the background
• See how much data was blocked and how much time you reclaimed
• An activity log and stats show exactly what Freezer blocked

★ FAST CONTROLS
• Home-screen widgets: Quick Toggle, Stats and Profile
• A Quick Settings tile to freeze and thaw without opening the app
• Freezes survive a reboot

HOW IT WORKS — LOCAL VPN (please read)
Freezer uses Android's VpnService to create a LOCAL, on-device VPN. This is the core feature and the only way an app can block another app's network access without root. Important:
• The VPN runs entirely on your device. It does NOT connect to any external or remote VPN server.
• No traffic is routed off your device. Packets from frozen apps simply enter a local tunnel and are dropped.
• Freezer does NOT read, log, collect, store, or transmit your network traffic, browsing, or any personal data.
• Only apps you choose to freeze are affected. Everything else bypasses the VPN.
• You grant the VPN permission via Android's standard dialog and can revoke it anytime in Android Settings.

PERMISSIONS
• VPN (VpnService): required to block frozen apps' network access (local only).
• Notification access: to silence notifications from frozen apps.
• Usage access (optional): only for auto-freeze when an app goes to the background.

PRIVACY
Your privacy is the whole point: everything stays on your device. Freezer has no backend, no account, and no cloud sync. Freezer shows ads through Google AdMob; where required (EEA/UK) you'll be asked for ad-consent, and you can choose non-personalized ads. Nothing else about your usage is collected.

Freeze the noise. Reclaim your focus, your data, and your battery — free, private, and on your device.

What’s new

Fixed: the VPN could stay on after tapping "Unfreeze All," even with no apps frozen. Thanks for your feedback — it helps us improve Freezer!
