Internet Doctor: Speed & Wi-Fi

Built by Solo

About this app

Internet slow, video freezing, calls dropping? Internet Doctor finds the cause and tells you in plain words what to do. No jargon, no sign-up.

Tap one button and get an answer in 20 seconds:
• ""Weak Wi-Fi signal. Your provider's internet is fine. Move closer to the router""
• ""Looks like a provider problem. Wi-Fi is stable, but internet access keeps dropping""
• ""Internet works great: enough for 4K video, calls and games""

FINDS WHERE THE PROBLEM IS
The app checks the whole chain: phone → Wi-Fi → router → DNS → provider → internet, and shows which link fails. On mobile data it knows there is no router and gives advice that actually helps.

IS IT FAST ENOUGH
Download and upload speed, latency and stability, with a clear verdict: good enough for video calls, online games, Full HD and 4K video?

SIGNAL MAP OF YOUR HOME
Walk through the rooms with your phone: the app draws a map of Wi-Fi and mobile signal, shows dead zones and suggests where to put the router. No need to draw a floor plan.

EVERY CHECK AT HAND
• Wi-Fi radar: walk around and watch the signal change, with sound and vibration
• Wi-Fi channels: are neighbouring networks in the way, 2.4 or 5 GHz
• Router: does it answer and how fast
• Wi-Fi or mobile data: which is faster right now
• With and without VPN: does the VPN slow you down
• Before and after a router restart: did it help
• Connection monitoring: when and for how long the internet drops
• Devices on your network

HISTORY AND REPORT
Test history for Wi-Fi and mobile data, with patterns like ""the internet gets worse in the evening, 9 to 11 pm"". An automatic check every 3 hours catches problems while you are not looking. A ready report for your provider's support in one tap.
