Next WiFi: Mobile Data Blocker

Mid-game or on a video call, unstable Wi-Fi can make your phone quietly move to mobile data. Next WiFi works as a Wi-Fi lock for the apps you pick: they stay on the Wi-Fi you started with, and if it goes down they are paused instead of jumping to mobile data or another network.

Pick apps and tap start
Choose the apps to protect and tap "Start Next WiFi mode". Pick one app or several, or select all. You can also search by app name. The first time, Android asks you to confirm the VPN permission.

A per-app mobile data blocker
Think of it as a mobile data block app that only touches the apps you chose. The moment you start, their traffic is pinned to the Wi-Fi you're connected to, so you can disable mobile data for apps you care about without changing your phone's settings. Even if the default connection changes, those apps keep using that Wi-Fi only. Everything else uses the internet as usual.

Stop switching to mobile data
If the starting Wi-Fi goes down, the chosen apps' traffic is paused and you get a notice right away. You decide whether to end the mode and go back to your normal connection, or keep the block on. Reconnected to another network? "Protect current Wi-Fi again" pins the apps to the new one.

Early warnings before it breaks
Next WiFi keeps an eye on Wi-Fi signal strength and link speed, along with response time and lost responses. From these it shows the current connection risk as a percentage. With notifications allowed, it alerts you when the risk passes 70% and again when things settle. When the signal weakens, it requests the Wi-Fi performance mode your phone supports. Results vary by phone, and it backs off automatically when the battery is low or the phone is hot or saving power.

A simple Wi-Fi monitor app
The Wi-Fi signal is shown in levels from Very good to Weak, with 1, 5 and 15-minute graphs of signal and response. When you end the mode, you get a summary of protected time, the weakest signal and how many times the connection dropped. The response time on screen is a direct check of this Wi-Fi's DNS route, so it differs from a game server ping.

Save mobile data, worry less abroad
Turn it on before opening apps where a network switch would hurt, like online games or video calls. It helps when you want to save mobile data on a tight plan, and when roaming data abroad is a worry because data roaming charges add up. When you end the mode, the chosen apps go back to your normal internet connection.

Works only on your phone
Next WiFi uses Android's VPN feature only to send the chosen apps through the starting Wi-Fi. This VPN runs entirely on your phone. It doesn't send your traffic, the sites you visit, your Wi-Fi name or your list of chosen apps to our servers. It doesn't boost signal strength. Its job is to protect the chosen apps' connection route. Android allows one VPN at a time, so turn off any other VPN before you start. The app is supported by ads and uses Google AdMob and Firebase for ads and app quality.
