ASO Tools: What to Evaluate Beyond the Keyword List
How to choose an ASO tool: data honesty, store coverage, keyword workflow, listing validation, rank checks, local-first storage, and total cost.
**ASO tools** mostly sell the same promise: a big keyword list and a difficulty score. The differences that matter show up later, when you try to turn the list into a listing, check a rank in a specific country, or keep the research trail for next month.
This guide is a buying framework, not a leaderboard. Use it to compare tools against the work you actually do.
Key takeaways
- Ask how volume and difficulty are derived; precision without method is a red flag.
- Check store and country coverage against your real markets.
- The workflow matters: research, scoring, writing, validation, and rank should connect.
- Local-first storage is a privacy and ownership advantage for some teams.
- Total cost includes subscriptions, API keys, and the time spent stitching tools together.
1. Data honesty
No tool has exact organic store search volume. A credible tool says so, labels estimates, and explains the inputs. A tool that presents a precise monthly number without a method is selling certainty it cannot have.
- Does it call volume an estimate or index?
- Does it show a confidence or coverage label?
- Does it explain where difficulty comes from?
- Does it distinguish web search data from store search data?
2. Coverage
| Dimension | Question to ask |
|---|---|
| Stores | Google Play and the App Store, or only one? |
| Countries | Which storefronts can I research and check? |
| Languages | Does localisation affect the data? |
| History | How far back does rank history go, and how is it sampled? |
| Exports | Can I get my data out as CSV, PDF, or JSON? |
Coverage is not a score. A tool with twenty countries you do not support is less useful than one with the three markets you actually sell in.
3. The workflow
Keyword research is one step. The real work continues into scoring, choosing fields, writing within limits, localising, and checking rank. If those steps live in different tools, you pay in context switching and copy-paste errors.
- Can I mine competitors from URLs or search?
- Can I expand with store autocomplete?
- Can I score and sort the list consistently?
- Can I write and validate both stores' fields?
- Can I localise without losing character limits?
- Can I check rank by market and keep the result?
4. Storage and privacy
Hosted tools keep your research on their servers. That is convenient for teams and a concern for developers who treat keyword strategy as private. A local-first desktop tool stores the project on your machine and uses your own LLM key for language steps. Neither model is universally better; choose the trade-off you want.
5. Total cost
Compare the subscription, any API usage, the number of seats, and the hours you spend moving data between tools. A cheap keyword database that does not connect to your listing workflow can be more expensive than a focused workspace.
Where NewASO sits
NewASO is a local-first desktop workspace for indie developers and small studios. It connects competitor mining, Play and App Store autocomplete research, heuristic scoring with confidence labels, listing validation, ten-locale localisation, and on-demand rank checks across 17 markets. It is not a paid volume provider, a hosted team dashboard, or a screenshot generator yet.
The honest comparison is not 'which tool has the most keywords'. It is 'which tool helps me make and remember a decision'. If that is your criterion, start with the ASO checklist and the features page.
Frequently asked questions
What is the best ASO tool?
There is no single best tool. It depends on your stores, markets, team size, budget, privacy preference, and whether you need research, listing writing, localisation, and rank checks in one place.
Are free ASO tools enough?
For a first pass, competitor listings and store autocomplete are enough. Paid tools add convenience and broader data, but they do not replace relevance judgement.
Does NewASO provide keyword search volume?
It provides a heuristic volume index with confidence labels, not exact monthly search volume. Apple and Google do not publish organic store query counts.
