Speed Check: Internet 5G WiFi

Tap once, wait about half a minute, and Speed Check shows how fast your internet really is. Bold, simple screens, big clear numbers, no account and no sign-up.

ONE TAP, THE NUMBERS THAT MATTER
• Download and upload speed in Mbps
• Ping and jitter
• Latency under load in each direction, graded for bufferbloat
• A rating from Excellent to Poor, with a quick verdict for video calls, HD and 4K video and gaming

ARE YOU GETTING WHAT YOU PAY FOR?
• ISP plan check compares your last 30 days with the speed of the plan you pay for
• Connection Doctor flags results below your plan or slower than usual
• Compare networks puts your mobile operators and WiFi networks side by side: median speeds, a bad-day speed and the best hour of the day
• With Pro, export a PDF plan report to keep or show your provider

MADE FOR 5G AND 4G
• Test on 5G, LTE/4G or WiFi
• LTE and 5G signal quality: RSRP, RSRQ and SINR, each rated
• Operator, roaming and VPN status on the Network information screen
• Lite test: download only, at most 25 MB
• Data saver makes Lite the default on mobile data, and full tests are capped on mobile data
• Data usage screen shows how much the app used

BAD RESULT? HERE IS WHY
The Connection Doctor explains the likely cause in plain language and how to fix it: weak mobile or WiFi signal, bufferbloat, high jitter, WiFi link rate, the 2.4 GHz band, VPN or roaming.

MORE CHECKS
Streaming test (start time, quality, buffering), ping monitor with packet loss, region latency map, DNS benchmark and a browsing test.

START EVEN FASTER
Run a check from a Quick Settings tile or by long-pressing the app icon.

YOUR RESULTS, YOUR DEVICE
History is stored on your phone only. Label results by place, add notes, share a result as an image (Private sharing hides the server city) and wipe it all with Reset local data. An optional coverage map, off by default, marks strong and weak signal spots. Auto picks the nearest Cloudflare server; regional servers (Pro) come from an open research project that publishes test data including your IP, so you are asked first.

FREE, WITH PRO IF YOU WANT IT
The free version shows ads and keeps your latest 20 results. Pro removes ads and unlocks unlimited history with trend charts, CSV export, the PDF plan report, scheduled tests with speed-drop alerts, home-screen widgets, any test server, a 60-second streaming test with saved runs and comparing every network over your whole history. Monthly, quarterly, yearly or lifetime, or watch an ad for 2 hours of Pro.

Light and dark themes. 12 languages.

Location is used only if you allow it, for place labels and the coverage map. Advertising and analytics SDKs may collect device identifiers and diagnostics.
