How App Store Ratings Work
When you open the App Store or Google Play to evaluate an app, the first thing you see is a star rating — typically between 1 and 5. That number is an aggregate average of user-submitted scores. Both major platforms also show a review count, which is as important as the score itself.

Apple and Google use slightly different methods for calculating ratings. Apple allows developers to reset their app's rating with each major version update, which means a freshly updated app may show a rating based on only a few recent reviews rather than its full history. Google Play, by contrast, weights ratings dynamically, giving more influence to recent reviews. Neither system is perfectly transparent about its exact formula.
Ratings are also segmented: you can often filter by current version, which helps you see whether a recent update improved or worsened user experience. For a broader picture of an app's reliability, see our end-to-end app security guide.
What a High Rating Genuinely Signals
A consistently high rating — say, 4.5 stars or above — across thousands of reviews is a meaningful data point. It suggests that a large, diverse group of users found the app functional and largely satisfying. Volume matters: a 4.8-star rating from 200 reviews carries far less statistical weight than the same score from 80,000 reviews.
Ratings are most informative when they reflect recent experience. An app with a 4.6 rating that holds steady over multiple versions is demonstrating sustained quality. Ratings that spike sharply after an update — especially an update that added a paywall or changed core features — deserve scrutiny.
Aggregate rating
A single average score calculated from all individual user ratings submitted for an app. It summarizes collective sentiment but can obscure important variation between user groups or time periods.
Review gating
A practice where developers prompt only satisfied users to submit ratings, artificially inflating average scores. Both Apple and Google prohibit this but it remains difficult to detect at scale.
Version rating
A filtered view of ratings submitted specifically for the app's current release. Useful for assessing whether a recent update helped or hurt the user experience.
Astroturfing
The practice of posting fake or coordinated reviews to make an app appear more popular or better-reviewed than it actually is. Often identifiable by clusters of vague, similarly worded reviews posted in a short timeframe.
Pay attention to how an app handles its permissions alongside its rating. An app that scores well but requests unusual access may still warrant caution. App permissions explained walks through which permission requests are worth questioning.
What Ratings Don't Tell You
Star ratings have real blind spots. They do not measure privacy practices, data collection, or long-term security. An app can earn a 4.7 rating while quietly harvesting location data or displaying aggressive advertising — practices most users never connect to the star-rating experience.

Both Apple App Store and Google Play host millions of apps, making algorithmic discovery — and therefore ratings — central to how users find new software.

Users who check ratings before downloading
According to a survey by Apptentive, the majority of users consult ratings and reviews before deciding to install an app.
Ratings also don't capture user intent mismatches. An app may perform exactly as designed but still frustrate users who downloaded it expecting something different. Those frustrated users may leave low ratings that reflect a mismatch in expectations, not product quality.
Finally, ratings do not tell you whether an app is safe to install. A well-rated app with suspicious permissions, unclear developer identity, or a very recent publication date warrants a closer look. Our pre-download safety checklist covers exactly what to verify before installing.
Spotting Inflated or Unreliable Ratings
Manipulated ratings are a known issue on both major platforms. Common patterns include a sudden surge of 5-star reviews with short, vague text; reviews posted within a narrow time window; and a large number of reviews from accounts with no other review history. These patterns can indicate coordinated review campaigns.
Ratings Can't Guarantee App Safety
A high star rating is not a security or privacy certification. Neither Apple nor Google uses ratings as an input into their safety review processes — those are separate systems. Always evaluate an app's developer credentials, permission requests, and update history independently of its star score.
Review text is often more revealing than the star score. Detailed, specific reviews that describe particular features, version numbers, or edge-case bugs tend to be more credible than generic praise. A 3-star review that describes exactly what broke and when can be more informative than ten 5-star reviews that say only "love this app."
Cross-referencing ratings across platforms also helps. If an app scores 4.8 on one store but has widespread complaints on independent tech forums or review aggregators, that discrepancy is worth investigating before downloading. Treat the star rating as one input in a broader evaluation, not a final verdict.
