Free ASO Score Checker
PopularSearch any app and get an instant ASO score with concrete fixes for title, subtitle, description, and keywords.
How healthy is your App Store listing, really? Search for any app above — yours or a competitor’s — and this checker grades its public metadata in seconds. It evaluates title length and keyword usage, subtitle quality, description structure, rating volume, and update recency, then rolls everything into a single ASO score you can act on.
Every point deducted comes with a reason: a title that leaves characters unused, a subtitle that repeats the title’s keywords, a description with no clear structure, or ratings too sparse to convert. That makes the score a to-do list, not just a number — and running it on the apps ranking above you shows exactly where they are beatable.
How to check an app’s ASO score
- 1
Type an app’s name into the search box and pick the right result, or paste its App Store URL directly.
- 2
Wait a few seconds while the checker fetches the listing and grades each metadata field.
- 3
Read the overall score, then expand each section — title, subtitle, description, ratings — to see what cost points.
- 4
Apply the recommendations to your listing in App Store Connect, then re-run the check after your next release to confirm the score improved.
- 5
Repeat the audit on your top three competitors to find weaknesses you can exploit.
What goes into an ASO score
App Store Optimization is not one lever but a stack of them, and each one is scoreable from public data. The checker examines how much of the 30-character title is used and whether it carries keywords beyond the brand name; whether the subtitle adds new keywords instead of repeating the title (Apple deduplicates terms across fields, so repetition is wasted space); how the description opens, since only the first few lines show before the “more” fold; and signal metrics like average rating, rating count, and how recently the app shipped an update.
The result is weighted toward the factors that move rankings and conversion the most. A short, brand-only title costs more points than a mediocre description, because the title is the strongest ranking field on the App Store. Likewise, a 4.8-star average built on forty ratings scores lower than a 4.5 built on forty thousand — volume is a trust signal that users and algorithms both read.
Using an ASO audit competitively
The fastest way to find realistic ranking opportunities is to audit the apps that already outrank you. When a top-charting competitor scores poorly on metadata — an unused subtitle, a title with no category keywords — that gap is your opening: they are ranking on brand momentum and downloads, and a better-optimized challenger can win the long-tail queries they ignore.
Run the check on three to five direct competitors and note where your score beats theirs and where it trails. Common patterns emerge quickly: many established apps coast on metadata written years ago, and many indie apps under-invest in ratings prompts. Turning those observations into a prioritized fix list is exactly what a paid ASO workflow does — this free score is the first step of it.
Frequently asked questions
What is a good ASO score?
Scores above roughly 80 indicate a well-optimized listing with full use of the title and subtitle, healthy rating volume, and recent updates. Most apps land in the 50–70 range, which usually means solid basics but wasted keyword space or thin social proof. Below 50 there is almost always a quick win available, like filling out an empty subtitle.
Can I check a competitor’s ASO score?
Yes. The checker works on any publicly listed iOS app, so auditing competitors is one of its main uses. Comparing your score against the apps ranking above you shows whether you are losing on metadata quality (fixable this week) or on rating volume and download velocity (a longer campaign).
What data does the ASO score use?
Everything comes from the app’s public App Store listing: name, subtitle, description, category, average rating, rating count, and last-update date. No App Store Connect access is required, which is also why competitor apps can be scored — the checker sees exactly what a shopper sees.
Does a higher ASO score guarantee better rankings?
No single score can, because rankings also depend on download velocity, retention, and keyword competition that public metadata does not reveal. What the score does guarantee is that you are not leaving free ranking potential unused — and among apps with similar download levels, the better-optimized listing consistently wins more search impressions.
How often should I re-run the audit?
Re-check after every metadata change ships (App Store metadata updates require a new app version) and roughly monthly otherwise. Rating counts and update recency shift over time, so a listing that scored 85 in January can drift down by summer without any change on your part.
Does this work for Google Play apps?
This checker audits Apple App Store listings. Google Play weighs metadata differently — the long description is indexed for search there, unlike on iOS — so a Play audit needs different scoring. Several of our metadata tools, like the keyword density checker, cover the Play-specific side.
