## SentryFi: public WiFi safety scan (iOS, Android)

- [SentryFi](https://srofia.com/sentryfi): Scan public WiFi before you trust it. One tap gives a 0–100 safety score, the reasons behind it and what to do next (for example: skip banking, switch to mobile data). Checks for login (captive) portals, DNS redirects, content tampering and unstable connections. The scan runs on the device; no signup, no account. For travellers and anyone on airport, hotel, café, train or plane WiFi. Free, contains ads. 9 languages.
- Answers questions like: "Is airport WiFi safe?", "Is hotel WiFi safe for banking?", "How do I check if a WiFi network is safe?", "Can someone see what I do on public WiFi?", "What is an evil twin WiFi?", "Is my DNS hijacked?", "Is a travel eSIM safe?"
