Светофор: статус сети

"Traffic Light" is a simple mobile internet status indicator. It helps you understand in just a few seconds what's happening with your network: is the internet working normally, has your operator enabled whitelisting, or has the connection completely disappeared.

The app was born out of a common problem: the internet seems to be working, the 4G icon is lit, but familiar websites, VPNs, messengers, and services suddenly stop working. 🤷‍♂️
You start wondering: is your phone broken? Is your VPN dead? Is your Wi-Fi glitching? Or are your operator throttling again?

"Traffic Light" helps you get a quick answer—no browsers, pings, or endless manual checks.

🚦 Quickly detects whitelisting

If your operator has restricted access to the global network and only allowed certain services, the app will show a yellow status.

It's immediately clear: the problem isn't with you or a specific app—it's just that whitelisting is enabled.

🟢 Green — internet is working properly
Access to the global network is open, and the connection is working normally.

🟡 Yellow — whitelists are enabled
Only certain permitted services are working, and a significant portion of the internet is limited at the operator level.

🔴 Red — mobile data is unavailable
Data transfer is not working, or the network is experiencing a serious failure.

🏢 Mobile network check even with Wi-Fi enabled

You can sit at home, in the office, or in a cafe with working Wi-Fi, and "Traffic Light" will still check your operator's mobile network.
This is convenient for understanding whether mobile data is limited or not working outside, even before leaving the building.

🛡️ VPN check

If VPN is enabled, the app will check whether the connection is passing through the VPN tunnel.

🟢 Green — VPN is working, and you can access the network. 🔴 Red — The VPN fails the test or the server is unavailable.

⭐ What the app can do

• Home screen widget — network status is visible without opening the app.
• Quick diagnostics: one glance and you'll immediately understand what's happening with your internet.
• History for the last 24 hours — conveniently track when restrictions or outages began.
• Mobile network checks in parallel with Wi-Fi.
• Enhanced mode with a customizable check period — useful when traveling or on an unstable network.
• TCP probing and TLS connection checking for more accurate detection of restrictions.
• The app is not a VPN, doesn't intercept personal traffic, and doesn't require registration.
• Free, ad-free, and doesn't collect personal data ❤️

"Traffic Light" was created as a practical tool for people who want to quickly understand what's happening with their mobile network: regular internet, whitelists, or a complete failure.
