Internet Speed Test: NextSpeed

Is your internet slow? NextSpeed helps you measure download and upload speed on Wi-Fi or mobile data, check connection latency and compare saved results over time.

CHECK YOUR CONNECTION
• Run an internet speed test and watch live download and upload measurements.
• View HTTP latency and jitter to understand response times and their variation.
• Compare Wi-Fi and mobile internet results by running tests on each connection.
• See general guidance for web browsing, video streaming, video calls and online gaming.

KEEP YOUR RESULTS
Save test history on your device, review average and best speeds, add notes, export CSV and share a result report. No account is required.

DIAGNOSE CONNECTION PROBLEMS
Use Network Doctor to check your active connection, DNS resolution and whether an internet endpoint is reachable. These checks help investigate a slow or unavailable connection; they do not repair your network or increase its speed.

YOUR LANGUAGE, YOUR DISPLAY
Choose from 12 languages, including French, German, Arabic, Turkish and Thai. Follow your device language, switch languages in Settings and choose a light or dark theme.

HOW MEASUREMENTS WORK
NextSpeed uses M-Lab NDT7 and an alternative Cloudflare HTTPS measurement engine. Results reflect the connection at the time of the test and can vary with your network, server and device. Latency uses HTTPS requests rather than ICMP ping. Packet loss is not measured.

Speed tests consume data, so take care on metered connections. Before testing, the app explains the provider's data policy and asks for consent. M-Lab receives and publishes measurement data and connection metadata, including your public IP address. Your history and settings stay on your device unless you export or share them. Test traffic uses generated data, never your personal files.
