## Description

Firewall Security AI – No Root is an advanced no-root Android firewall and app blocker with an on-device AI security engine. It shows which apps access the internet, blocks trackers and spy servers, and logs connections with app, host, and country so you can block them with a single tap and prevent data leaks before they happen.

Key capabilities include on-device filtering via a local VPN (no root required), DNS privacy with secure or custom DNS options, and an IPS-style system that uses up-to-date filter lists to stop known outbound threats. The app provides live connection logs, per-app rules, data counters, and quick filters to help you maintain control. All decisions are made on-device, preserving privacy and reducing the risk of data leakage, with no account needed and Android 15 compatibility.

## Review summary

Overall sentiment praises the app for strong ad blocking and privacy features, with several users calling it reliable and well-designed. However, recurring issues include VPN always-on stability, background running glitches needing toggling, DNS connectivity problems across providers (often not working except Google DNS), and licensing frustrations (subscription not recognized, paywalls, pricing). Some users question AI claims and feature availability behind a paywall. In short: highly valued for privacy and ad-blocking, but stability and billing issues hinder daily use.

### Pros

- Strong ad blocking leading to a cleaner, ad-free browsing experience.
- Solid privacy and security features that help block hackers and protect data.
- Good design and overall reliability; described as top notch and works flawlessly.
- Useful DNS/control capabilities and firewall functionality for smart home/IoT setups.

### Cons

- VPN/always-on issue: app disconnects and requires toggling Off/On, impacting background use.
- DNS connectivity problems across networks/providers; many DNS servers fail to connect (often only Google DNS works).
- Subscription and licensing issues: some users report subscription not applying, pricing models (annual vs lifetime) and concerns about paywalls.
- Perceived lack of AI features or overpromised AI capabilities; some features locked behind paywalls.
