Internet Speed Test: 5G & WiFi

Internet Speed Test: 5G & WiFi measures how fast your connection really is, in about half a minute, with no account and no sign-up.

Run a test over mobile data (5G, LTE/4G) or WiFi and get clear results:
- Download and upload speed in Mbps
- Ping (latency) and jitter
- Latency while downloading and while uploading, each with a bufferbloat grade, so you see which direction makes calls and games lag

WHAT YOUR RESULT MEANS
Each result gets a rating (Excellent, Good, Fair or Poor) and shows whether the connection suits video calls, HD streaming, 4K video and online gaming.

CONNECTION DOCTOR
After every test, a plain-language checklist of what is slowing you down and how to fix it: weak WiFi or mobile signal, bufferbloat, WiFi link rate as the limit, speed below your plan or slower than usual, high jitter, 2.4 GHz band, VPN or roaming.

STREAMING TEST
Plays a simulated adaptive video from the test server and reports start time, the quality it settles on (up to 4K on WiFi, 1080p on mobile data) and any buffering.

LITE TEST AND DATA SAVER
A Lite test measures download only and uses at most 25 MB. Turn on Data saver to make it the default on mobile data. Full tests are capped on mobile data, and a Data usage screen counts what the app used.

LABELS AND NOTES
Tag results Home, Office, Bedroom, Car or your own place, add a note, then filter history by place.

NETWORK TOOLS
- Ping monitor: live latency, jitter and packet loss
- Region latency: ping to servers around the world on a map
- DNS benchmark: your DNS vs 1.1.1.1, 8.8.8.8 and 9.9.9.9
- Browsing test: how fast web pages load
- ISP plan check: your last 30 days vs the plan you pay for
- Network information: IP, WiFi standard, band, channel, signal in dBm, operator, roaming and VPN. WiFi name and cell details appear only if you allow location and phone state

CHOOSE YOUR SERVER
Auto picks the nearest Cloudflare server. Regional servers (Pro) are run by an open research project that publishes test data, including your IP address, as open data, so the app asks you first.

HISTORY AND COVERAGE MAP
Every test is saved on your device so you can compare networks, places and times. Share a result as an image. The coverage map (off by default) shows where your signal is strong or weak, with an approximate place stored only on your device.

QUICK ACCESS
Start a test from a Quick Settings tile or by long-pressing the app icon.

PRIVATE BY DESIGN
No account required. Your history stays on your device, and Reset local data wipes it in one step.

FREE WITH ADS, PRO OPTIONAL
The free version keeps your latest 20 results. Pro removes ads and adds:
- Unlimited history and speed trend charts, also per place
- CSV export and a PDF plan report with the Connection Doctor
- Scheduled tests with speed-drop alerts
- Streaming test long watch (60 s) and saved runs
- Home-screen widgets and any test server
Plans: monthly, quarterly, yearly or lifetime. Not ready? Watch an ad to unlock Pro for 2 hours.

Useful for checking home WiFi, comparing mobile operators, verifying what your provider promises and fixing laggy video calls.

Light and dark themes. Available in English, Vietnamese, Spanish, French, Hindi, Indonesian, Japanese, Korean, Thai, Arabic and Chinese (Simplified and Traditional).

Note: the app uses location only if you choose to share it, to label results by place and show the coverage map. Advertising and analytics SDKs may collect device identifiers and diagnostics. Privacy policy: https://speedtest.fighttech.vn/privacy
