ShieldWall is a no-root, per-app firewall that puts you in charge of what your phone connects to. Block ads, trackers, and unwanted apps on Wi-Fi and mobile data — with a live view of everything happening on your network
…rk.
Per-app firewall
Allow or block any installed app independently on Wi-Fi and mobile data. Filter by All, Custom, Blocked, or Allowed, search by app or package, and open apps directly from the list.
Domain & IP blocklist
Block exact domains, wildcards (*.example.com), single IPs, and CIDR ranges. One-tap preset lists cover Ads, Trackers, Malware, and Telemetry, and every rule can be toggled on or off.
Profiles & schedules
Save named rule sets (Standard, Work, Night, Guest) and switch your whole firewall config in one tap. Schedules auto-switch profiles on day-of-week and time windows — including overnight ranges like 22:00–07:00.
Live traffic monitor
Watch real-time down/up throughput on a 60-second chart, see top talkers with blocked-data bars, and track session stats: data blocked, data allowed, and blocked events.
Audit log & CSV export
Every evaluated connection is logged with its decision and reason — app rule, lockdown, domain, or IP. Search and filter, review lifetime counters, and export the full audit trail as a CSV via the system share sheet.
Lockdown mode & master switch
Flip to lockdown to block everything except apps you explicitly allow, or disable the firewall entirely with one master switch.
No root required. Enforcement runs through Android's own VpnService — DNS is inspected on-device, blocked domains are sinkholed, and blocked addresses are dropped at the tunnel, per app.
