Speedtest by Ookla

Measuring download, upload and latency

The classic speed test runs with one tap and reports download speed, upload speed, and three separate latency figures. Latency is the delay before a connection responds, and the three measures let you see where that delay sits. The developer positions the test for checking a slow connection and for confirming a network is ready before a gaming session.

Results are stored in a history of past tests, which can be shared directly from the app. That history makes it possible to compare readings taken at different times or places.

Checking outages on apps and services

The Downdetector section shows real-time status for online apps and services. You can follow specific services so that status changes and disruptions appear as they happen. You can also report a problem you are seeing, which feeds into the same reporting system.

This part is useful for telling a faulty home connection apart from a service that is down for everyone.

Mobile coverage maps and video streaming tests

The Maps tab uses real-world test data to show where each mobile provider has strong and weak coverage in your area. It also marks where 5G is available and shows which network technology is most common where you are. Coverage can be compared between providers before you choose one or check a dead spot.

The video test estimates the streaming quality your network can currently support and suggests changes to improve online video. It is intended for planning before a film or series is streamed.

Ads and the ad-free option

The app shows ads by default. The listing offers an option to remove them, which is presented as an alternative for people who want Speedtest without ads.
