Independent, consent-based testing

Know what monitoring apps can actually see.

We test social viewers, parental controls, family locators and privacy tools on accounts and devices we control. Every verdict separates observed results from vendor claims.

Find the right kind of answer

Start with the question you are trying to answer. Each guide explains what is possible, what requires permission and which marketing claims did not survive testing.

A repeatable test, not a first impression

Every article follows the same process, making results easier to compare and easier to re-check when an app changes.

Read the full methodology
  1. STEP 01

    We create or purchase the accounts

    Every test runs on accounts and devices we control — bought at retail, configured like a real household, never vendor-supplied.

  2. STEP 02

    We test the advertised functionality

    We reproduce each marketing claim as written, on both platforms where relevant, and record exactly what appears.

  3. STEP 03

    We document limitations and consent requirements

    Where a feature works only with consent, permissions or specific conditions, we say so — the conditions are the finding.

  4. STEP 04

    We date every check and record meaningful changes

    Each article carries its last-checked date and an update history, so you know when the facts were current.
