ASO Keyword Gap Checker
Find keyword gaps in your App Store or Play Store listing. See top competitor terms you don't use — free lite checker from Nakxi.
What is an ASO keyword gap?
A keyword gap is a term (or phrase) your competitors put in title, subtitle, or description that your listing never uses. Closing gaps is one of the fastest ways to improve discoverability without rewriting every screenshot. This free checker samples rivals near your listing and highlights top competitor terms you are missing — a lite preview of the deeper keyword intelligence inside Nakxi.
App Store and Play Store coverage
Paste a public iOS or Android store URL. Nakxi finds rivals from listing signals and compares their metadata language to yours. Results are a sample for prioritization, not a complete keyword research database. Use them to decide which terms deserve space in your 30-character title or subtitle next.
What you get — and what to do next
You’ll see top gaps with how many sampled competitors use each term, plus quick context for your own app. After you pick candidates, run Analyze My App for a full listing score, Compare with Competitors for side-by-side title and description length, or read our guide on finding competitor keyword gaps before launch.

Keyword Gap Checker FAQ
What is an ASO keyword gap?
A keyword gap is a term competitors use in their App Store or Play Store listings that your app does not. Closing gaps can improve category relevance and search visibility.
How does the keyword gap checker work?
Paste your store URL. Nakxi reads your title, subtitle, and description, samples competitor listings in your category, and surfaces searchable ASO terms you are missing — not rival brand names.
Should I add every gap keyword?
No — prioritize terms that match user intent and your product. Use gaps as research input, then test title, subtitle, and screenshot copy updates in Nakxi.
Is this the same as full keyword research?
This lite tool shows a quick gap preview. Nakxi Growth includes full keyword insights, ranking tracking, and competitor panels inside your project.
