Our methodology

How AppDuo tests and scores apps

Every recommendation must answer four questions: who it suits, why, what the evidence is and what you trade off. This is the process we use to answer them.

Six steps behind every review

From picking a product to publishing and keeping it current.

  1. 01

    Choosing what to review

    Driven by search demand, reader questions and how widely the product is used. We never accept payment to review a product.

  2. 02

    Collecting official sources

    The vendor’s pricing page, documentation, privacy policy, terms and changelog — each saved with its link and the date we read it.

  3. 03

    Gathering user feedback

    Public ratings and reviews on the App Store, Google Play, G2, Capterra, Trustpilot and communities — only numbers we can verify.

  4. 04

    Scoring on evidence

    Each criterion has a written rationale based on features, price versus peers, user ratings and documented incidents.

  5. 05

    Verifying prices and policies

    Prices, free-plan limits, refunds and privacy are checked against official sources, with the check date recorded.

  6. 06

    Editing, updating and hands-on testing

    Anything older than 90 days is re-checked. Reviews an editor has used hands-on are labelled “Tested hands-on” with the devices, plan and scenarios run.

Six scoring criteria

Each criterion is scored 0–10 with a rationale. The overall score is a plain average with no hidden weighting — set your own weights in the compare tool.

Our transparency commitments

Scores can’t be bought

Partners and advertisers never preview, edit or influence verdicts.

Editorial policy

Affiliate & sponsorship labels

Affiliate links and sponsored placements are labelled in place and kept out of rankings.

Advertising disclosure

Public corrections

Meaningful errors are fixed and logged with a date in the product’s change history.

Corrections

Right of reply

Developers can respond officially; replies are shown separately from our verdict.

Regular updates

Every page shows when prices were verified; after 90 days a warning appears and it is re-checked.

A real version per language

English, Japanese and other editions are written for readers of that language and published independently — not word-for-word machine translations.
