Free app-store SEO tools
Better inputs.
Sharper launches.
These basic ASO tools help you improve the words that influence app-store discovery and conversion. They run in your browser, require no account, and show the logic behind every result.
Store listing
ASO Metadata Checker
Audit an Apple App Store or Google Play title, subtitle, short description, full description, and keyword field against current limits and practical quality checks.
Keyword research
App Keyword Opportunity Checker
Pressure-test a seed keyword using specificity, search intent, breadth, and likely competitive pressure. Every score explains its inputs and limitations.
iOS discoverability
iOS Keyword Field Optimizer
Pack priority phrases into Apple's 100-character field while removing exact duplicates, generic filler, and terms already covered by visible metadata.
Customer language
App Review Theme Analyzer
Paste reviews to surface recurring complaints, praise, feature requests, sentiment, and repeated customer phrases with local rule-based analysis.
Listing conversion
App Store Conversion Calculator
Translate a conversion-rate target into monthly, quarterly, and annual install scenarios using your own visitor and value assumptions.
What these tools can—and cannot—tell you.
Useful now
Field limits, repetition, character packing, review-language patterns, phrase specificity, and conversion scenarios are actionable with your own inputs. The tools expose overlooked problems and create a stronger research brief.
Needs deeper evidence
Live keyword demand, rank history, country variation, competitor strength, representative review samples, and achievable conversion targets require external evidence. Results show where AppSignal data should replace a heuristic.
Why ASO is more than keyword stuffing
App-store optimization sits between discovery and conversion. A relevant phrase can help a listing meet the right search intent, but the listing still needs a clear promise, credible screenshots, strong ratings, and a product people keep. Repeating the same words cannot repair weak positioning.
Use the metadata checker and iOS optimizer to make each limited field do a distinct job. Use the opportunity checker to turn a broad idea into testable keyword territories, the review analyzer to recover customer language, and the conversion calculator to make the expected impact explicit. Each result is a hypothesis—not a guarantee of rank or growth.
When a direction looks promising, AppSignal adds the missing context: which apps already occupy the market, how their signals are moving, what countries differ, and where estimates remain uncertain. That is the bridge from a free local check to a defensible growth decision.
