What it does:

- Accurately measure the performance of your mobile broadband service by running active tests to evaluate the following metrics - download and upload speed, latency, jitter and packet loss.
- You can run these tests over both Wi-Fi and cellular connections.
- The data from these tests contributes to the FCC’s Measuring Broadband America program. The program is run by the FCC to fulfil its Congressional mandate to collect and make publicly available accurate and transparent performance metrics on US broadband.
- Your privacy is completely safeguarded. No personally identifiable information is collected.

How it works:

- You can selectively run manual tests in the app across download speed, upload speed, latency, jitter and packet loss to accurately measure broadband or cellular performance.
- You can set a monthly data usage cap to ensure tests do not go over the limit. You can also monitor data usage in the app so you do not exceed monthly allowances by your carrier.
- Using the built in GUI, it’s easy to compare tests and historical data collected to see how performance changes over time, or according to wifi/cellular connection.
- In addition to the test-generated in app information you can also export additional data collected during a test. This passive data such as Cell ID, Signal Strength and GPS location can be used to further analyze performance across time and locations.

As part of the Measuring Broadband America Program The FCC Speed Test App assists with improving the visibility, accuracy and transparency of performance data on US mobile broadband.

Seems to be clear and accurate, but Upload test fails for me

I’m on a microwave relay link in Oregon - the only broadband option I have - and this app correctly reports my expected download speed, which accords with my own anecdotal observations.
However the app’s “upload” test reports FAILED immediately, which - considering that uploads from my network via browser, SFTP, icloud, email, etc, all work fine - makes me suspect the app has an issue. I’ve tried multiple times without success, and I see from these reviews that I’m not alone seeing this behavior. I know these reviews aren’t meant to be tech support, but there doesn’t seem to be any (obvious) way to submit a problem report from within the app.

Dark Mode and Hardwire

Can we please have dark mode in this app? It’s 2021 folks, this should be considered basic requirements at this point. Also to get true speed measurements there really needs to be a PC, MAC and Linux version that can be used with a hardwire. I’m sure we can probably devise physical LAN with a mobile device but this requires adapters and probably won’t be as quick.

Speed test with FCC minding the store

This refers to the version of the app released January 2021. The app seems to be transparent about privacy and can be constrained to not use to minimize mobile data. The app is light weight by modern standards, “only,” 35 megabytes.

This app seems to give somewhat more optimistic performance ratings than Ookla or Dslreports/speetest. Hmm, maybe ISPs are cooking the books a little to make sure that when Uncle Sam is watching, performance looks better than it would otherwise. This app can’t be faulted for any cooking of the books ISPs might do.

It is worthwhile to run this app so Uncle Sam can build an ISP performance database.
