Free Internet diagnostics for Android

Diagnose your Internet before you call your ISP.

When the connection feels slow, unstable or simply wrong, Diagnostix360 checks the path from your phone outward, shows what may be happening and gives you a clear next step. If you still need support, take a report with you.

How it works

From a vague problem to something useful.

The app starts with what you are actually experiencing, runs a measured check, then turns the result into a practical next step.

See the diagnosis happen

More than a speed test.

A speed number alone rarely tells you where to look. Diagnostix360 follows the connection path and shows the result in context.

Take evidence into the conversation

If you still need support, do not start from zero.

A completed Check can produce a clear Customer report or a much more detailed Technical report. The Customer sample below is complete. The Technical preview contains seven selected pages from a real 27-page sample.

Public samples use synthetic demo identifiers. The full Technical Report is exhaustive and varies with the evidence collected. It is typically about 20+ pages; this real sample contains 27 pages. The app warns you before sharing a Technical report because your own report can contain network details.

Inside the Technical report

When the problem comes and goes

Watch the connection while it is misbehaving.

Live Test keeps a rolling view of local, Internet and stability evidence so intermittent drops and changing conditions are easier to catch while they are actually happening.
