ASO Keyword Checker
for the App Store
Type a search term, pick a country, and see the 25 iOS apps ranking for it right now — with a competition score and the top-10 slots you could realistically take.
Check a keyword in under a minute
The checker pulls live results from Apple’s public App Store search data — the same index your app competes in — and scores the top 10 so you can decide whether a keyword deserves a spot in your title.
Enter one search term
Use the phrase a user would actually type. Two or three words usually tell you more than one broad word.
Pick the storefront
Rankings differ by country. A term that’s crowded in the US can be wide open in India, the UAE or Brazil.
Read the top 10
See who holds each position, how many ratings they carry and when they last shipped an update.
Four numbers that tell you if you can rank
Competition score
0–100, built from how many ratings the top 10 apps hold (weighted toward positions 1–3) and how many have the exact term in their name. Under 35 is an open field, 35–65 is contested, above 65 is crowded.
Title matches
How many of the top 10 put every word of your keyword in their app name. A low count means Apple is ranking on relevance alone — a new app with the term in its title can move in fast.
Winnable slots
Top-10 positions held by an app with fewer than 1,000 ratings, or one that hasn’t been updated in over a year. These spots move first when a stronger, fresher listing shows up.
Median ratings
The typical rating count you’re up against. Rating volume is one of the strongest App Store search signals, so this tells you how much review velocity you’ll need.
Found a good keyword? Five moves that get you ranked
- Put it in the app nameThe 30-character name carries the most ranking weight on iOS. Lead with the brand, follow with the term.
- Use the subtitle for the second termAnother 30 characters, also indexed. Don’t repeat words already in the name.
- Fill the 100-character keyword fieldCommas, no spaces, singulars only, and no words that already appear in the name or subtitle.
- Localise per storefrontEach country has its own keyword field. Run this checker per market and target different terms where competition is lower.
- Ship updates and ask for ratingsFresh versions and steady rating velocity are how the winnable slots above got opened up in the first place.
Questions about the ASO keyword checker
Is this ASO keyword tool free?
Yes. No account, no card, no daily cap on our side. Apple limits how fast any one connection can query its search data, so if you run dozens of checks in a row, wait a minute and try again.
Where does the data come from?
From Apple’s public App Store search data, fetched live when you click “Check keyword”. Nothing is cached or estimated except the competition score, which we calculate from the live results.
Why is the order slightly different from my iPhone?
On-device App Store search adds personalisation, Search Ads placements and frequent re-ranking. The public search data tracks it closely but won’t always match position for position.
Does it show search volume?
No. Apple only shares keyword popularity inside Apple Search Ads. Use the popularity score there alongside the competition score here: high popularity plus low competition is the combination you want.
Does it work for Google Play?
Not yet — this version covers the iOS App Store in 20 countries.
What competition score should I aim for?
For a new app with few ratings, stay under 35 and look for keywords with three or more winnable slots. Established apps with thousands of ratings can go after the 35–65 range.
