Diagnose · 4 min read · Practical ASO guide

ASO tools. Buy evidence, not a dashboard collection.

Choose the decision before choosing the subscription. A tool can help compare keywords, check copy or organize a test; it cannot decide whether a promise is true for your app. This guide maps the jobs to useful tool categories and explains what to inspect. The dashboard collection does not need another dependent.

Leave with a decision

Leave with an output that helps somebody do the next piece of work.

Start with the visual explanation, work through the example, then try the exercise on your app.

Visual field notes · 01

Which tool should you open first?

Start with the decision, not the size of the tool dashboard.

  1. Do you know the problem?

    Write the question you want the tool output to help answer.

  2. Not yet → diagnose

    Use the audit checklist to record evidence and prioritise the question.

  3. Yes → choose the task

    Use metadata tools for text, the storyboard for creative, review research for themes or the test planner for hypotheses.

What this meansThese tools organise your work. They do not magically provide private competitor data or guaranteed rankings.

Work through it · fictional example

Pick the tool by the decision you need to make.

The fictional Speak Daily team has a list of keywords, vague screenshots and no agreed test. Buying another dashboard will not connect those pieces.

Illustrative diagnose example: Research: candidate decisions; Build: copy and storyboard; Measure: a test brief.
Illustrative decision map for the fictional example above. Proposed changes and assumptions are not measured results.

Why this changes the decision

Use the keyword workbench to record relevance and sources, then transfer the approved ideas into a listing draft. Build a storyboard that proves the same promise. Use the experiment planner to record the proposed change, metric and interpretation rule. Export the work with its assumptions attached.

What to check before calling it a win

Ask whether a teammate can use the export without a meeting to decode it. A tool that counts characters cannot tell you whether the message is persuasive; a clean report cannot create evidence you did not supply.

Your turn · a five-minute start

Make one useful decision for your app.

Choose one unresolved decision and one tool. Write the output you expect before entering data.

What a useful answer looks like

“A prioritized list of three relevant terms with sources” is a usable output. “More insights” is not.

Separate the jobs

An ASO tool may provide market research, rank observations, metadata editing, creative testing or reporting. Those jobs require different evidence and capabilities. Start by naming the decision you cannot currently make. Buying a broader dashboard does not help if the actual problem is an unclear product message or a missing owner for implementation.

Use your consoles as a starting point

Native store consoles provide access to your own app’s reporting and supported workflows. Third-party estimates can add context but should not silently replace measured first-party data. Keep the origin of every metric visible. A public scanner cannot know your hidden iOS keyword field, private conversion results or retained user value without an appropriate data connection.

A useful tool output becomes an action

Do not leave the result stranded in another tab.

  1. Input

    Enter relevant, accurate material with its source and context.

  2. Interpret

    Read what the tool actually measures and what it cannot tell you.

  3. Decide

    Choose one change or investigation supported by the output.

  4. Handover

    Save the result, assign an owner and define how you will verify the work.

What this meansA score without an explanation and a next action is just a number wearing a tie.

Evaluate research data with a small trial

Choose a real app, target market and set of questions. Check whether a provider covers the needed storefronts, how observations are dated and what its scores mean. Ask about exports and history retention. A precise-looking number is not necessarily a measured search count. Compare usefulness for your actual workflow rather than ranking tools by the number of features on their pricing pages.

Use utilities for concrete preparation

A metadata checker, keyword-field builder or image checker can catch formatting issues and make drafting easier. These utilities do not decide product relevance or guarantee rankings. The free tools on this site show their limitations and process inputs locally, so you can complete a small task without connecting a store account.

Make a purchase decision you can revisit

Record the problem solved, required coverage, seat needs, recurring cost and exit/export options. Test the workflow before committing to a longer term. Reassess whether the team actually uses the outputs in decisions. This page is a buying framework, not a scored vendor ranking: no hands-on evaluation or price comparison is implied.

Your next steps

  • Write the decision the software needs to support.
  • Identify whether the required data is measured, observed or estimated.
  • Trial the exact store/market workflow and export the result.
  • Compare total operating cost and revisit usage before renewal.

Questions and answers

Does this guide rank commercial tools?

No. It provides an evaluation framework and links to practical utilities. A vendor ranking would require a documented hands-on method and dated evidence.

Can a free checker replace an ASO strategy?

It can remove mechanical friction. Strategy still requires deciding which users to serve and which changes the evidence supports.

Work directly with Gabriel

Make your team harder to bullshit.

Use your own app to practise keyword choices, metadata drafts, screenshot briefs and evidence review. Leave with a method your team can repeat after the workshop. The next agency deck should face a tougher audience.
