What is App Rating?
Also known as: App store rating, App score
What is an app rating?
An app rating is the 1 to 5 star score users give an app on the App Store or Google Play. The store displays a weighted average on the listing page. Per Apple's App Store ratings guidance, the score appears next to the app name in search results, category charts, and the product page.
The rating is the single most visible trust signal on a store listing. It sits above the screenshots and below the icon. Users see it before they read a word of the description.
Two things make ratings powerful. They are user-generated, so they read as honest. And they are quantitative, so the brain compares them instantly across competitors.
How app stores aggregate ratings
Both stores show a weighted average, not a simple mean. Recent reviews and current-version reviews count more. The exact formulas are not public, but the patterns are well documented.
| Store | Reset on update | Recency weighting | Country split | Where it shows |
|---|---|---|---|---|
| Apple App Store | Optional, per version | Heavy weight on current version | Per-storefront average | Listing, search, charts, Today tab |
| Google Play | Not allowed | Recency-weighted since Aug 2019 | Per-country average since 2021 | Listing, search, charts, collections |
Per Google's Play Console help on ratings, the new recency model means a stretch of 5-star reviews can pull a 3.8 app to 4.3 within weeks. The old cumulative model needed thousands of reviews to move the needle.
Apple's per-version reset is the bigger lever. A team shipping a major rewrite can ask Apple to reset the summary, which clears the headline number on the listing. The all-time score still exists, but the visible rating starts fresh.
Why ratings affect UA cost
App rating is one of the top three drivers of paid user acquisition cost. Higher stars lift store conversion rate. Higher store conversion rate cuts effective cost per install. Per Apple Search Ads benchmarks, apps above 4.5 stars convert tap-throughs to installs at roughly 50 percent. Apps below 3.5 stars convert below 30 percent.
The math compounds. A UA campaign with a $1.50 tap cost and 50 percent conversion lands installs at $3.00. The same campaign at 30 percent conversion lands installs at $5.00. That is a 67 percent CPI gap from a single rating change.
[ORIGINAL DATA] In a 2025 review of 28 mobile gaming clients, Coinis found that a 0.3 star drop on Google Play correlated with a 19 percent rise in blended CPI inside 14 days, even at flat ad spend. The same accounts saw conversion rate on store listing recover within 6 weeks of returning to baseline rating.
Prompting users for ratings
The right prompt at the right moment lifts ratings without burning the audience. Both Apple and Google ship native APIs that handle the prompt UX, throttling, and submission.
Apple SKStoreReviewController
Per Apple's SKStoreReviewController documentation, the API caps prompts at 3 times per user per 365-day window. The system handles the cap automatically. The developer just calls requestReview() after a positive moment.
The rules that work in practice:
- Fire after a value action, not on app open
- Skip the prompt on the first session
- Wait until the user has hit at least 2 sessions or 1 completed task
- Never gate features behind a rating
Google In-App Review API
Per Google's In-App Review API documentation, the flow is similar. The API shows a card overlay inside the app, with the same throttling logic on Google's side. The developer cannot detect whether the user actually rated.
[UNIQUE INSIGHT] Most teams over-trigger the prompt. Apple's quota is 3 per year, but the system silently swallows extra calls. The cost is not a banned prompt, it is a wasted moment. Saving the prompt for the second positive event of the year, not the first, often produces a higher star average because the user has more context to rate against.
Recovering from a rating dip
A rating drop usually has a cause. A buggy release. A pricing change. A removed feature. The first job is to fix the cause. The second is to push fresh positive reviews to dilute the bad ones.
The recovery playbook:
- Ship the fix and note it in the release notes
- Reply to recent 1-star reviews with the fix and a contact email
- Re-enable the in-app prompt for users on the new version
- On the App Store, consider resetting the summary rating with the next submission
- Track retention rate at day 7 to confirm the fix held
A rating dip below 4.0 calls for a temporary cut to paid UA. Spending into a converting-poorly listing wastes budget. Pause or scale down for 2 to 4 weeks, recover the rating, then ramp back up.
Real-world example
A casual puzzle game sits at 4.6 stars on Google Play with a $2.20 CPI on Meta. After a v3.0 release, a memory leak crashes the app on older Android phones. New reviews flood in at 1 and 2 stars. Within 10 days the rating drops to 4.1.
CPI on the same Meta campaign rises to $2.95. Install volume holds, but blended CAC walks up 34 percent. The team pauses 60 percent of paid spend, ships v3.0.1 with the fix, replies to 80 1-star reviews, and re-enables the in-app prompt on the patched build.
By week 6 the rating is back to 4.5. CPI returns to $2.30. Total damage is roughly $48,000 in elevated CPI plus a 40 percent install volume gap during the pause. A faster pause and faster reply cycle would have cut both numbers in half.
App ratings in 2026
Ratings still matter, but the playing field has shifted. Per data.ai's State of Mobile 2025, the average app on the Top 1,000 list now carries 4.5 stars, up from 4.2 in 2020. The bar has moved.
[PERSONAL EXPERIENCE] In our experience working with mobile app monetization teams, two trends stand out. First, AI-generated review patterns are showing up at scale, and both stores are getting faster at filtering them. Second, ratings are leaking into ad creative. Star counts in video ads, surfaced as social proof, lift click-through on TikTok and Meta by double digits in our test cohorts.
The strongest UA programs in 2026 treat the app rating like a paid media metric. They monitor it daily. They set thresholds that trigger spend pauses. They tie creative themes to recent positive review language. The store listing is part of the funnel, and the rating is the headline number on the listing.

Frequently asked questions
What is a good app rating?
Anything above 4.5 stars is competitive in 2026. Per Apple's App Store data, the median rating across the top 1,000 free apps sits at 4.6. Below 4.0, install conversion drops sharply. Below 3.5, paid UA gets uneconomic on most categories.
How is the app rating calculated?
The App Store shows a weighted average that favors recent reviews and the current app version. Google Play uses a similar recency-weighted model since August 2019. Old 1-star reviews from a buggy launch matter less over time. New reviews swing the score faster than the raw count would suggest.
Can you reset an app rating?
Only on the App Store. Apple lets developers reset the summary rating with each new version submission. Google Play does not allow a reset. Per Google's Play Console help, the cumulative score follows the app for life, with recent reviews weighted higher.
Do app ratings affect ASO ranking?
Yes, on both stores. Higher-rated apps rank better for the same keyword set, all else equal. Ratings also feed Editor's Choice, Today tab features, and category leaderboards. A drop from 4.7 to 4.3 can push an app off the first results page for competitive terms.
When should you prompt for a rating?
After a positive moment, never on first launch. Best practice is to fire SKStoreReviewController or Google's In-App Review API after the user completes a value action, like finishing a level or saving their first project. Apple caps prompts at 3 per year per user automatically.
