Short answer: Google Play, the App Store and Walmart all let you reply publicly to reviews, each with its own rules, while Amazon's official review policy focuses on what reviews may contain rather than on brand replies. Below, you'll find what each platform says as of Oct 16, 2026, a triage checklist and reply patterns you can adapt. Rules change, so check each linked page before you rely on it.

Q: Can developers reply to Google Play reviews?
Yes, developers can reply to Google Play reviews from the Reviews page in Play Console or through the Google Play Developer Reply to Reviews API, which accepts replies of up to 350 characters, and Google says you can see and reply to new reviews during the roughly 24 hours before they are posted publicly.
That's from Play Console Help and the Reply to Reviews API guide (as of Oct 16, 2026). The API covers production versions only, and only reviews that include a comment. Its default quotas are 200 GET requests per hour and 2,000 POST requests per day.
Q: Can you reply to App Store reviews?
Yes, Apple lets App Store Connect users with an Admin or Customer Support role respond to any review of their app, no matter when it was written; the reviewer is notified and can update their review, and you can edit your response at any time, with only the latest version shown on the product page.
Apple also asks that responses stay respectful and leave out personal information, marketing language and spam, and recommends personalizing replies rather than using generic ones for similar reviews (Apple Developer, as of Oct 16, 2026).
Q: Can brands reply to Amazon reviews?
Amazon's official review policy page explains what reviews are allowed and how fake reviews are stopped, but it does not describe a public reply feature for brands, so check your own Seller Central account for the tools currently available to you rather than assuming a reply box exists or works like the app stores.
What the Amazon policy page does make clear (as of Oct 16, 2026): Amazon removes reviews from anyone with a direct or indirect financial interest in the product, reviews by a manufacturer posing as an unbiased shopper, and reviews given in exchange for a monetary reward. The same page says selling partners can't offer compensation for a positive or negative review, and can't edit a review or ask customers to edit or remove one. So whatever you do on Amazon, don't write reviews about your own product, and don't pay for them.
Q: Can sellers respond to Walmart reviews?
Yes, Walmart Marketplace sellers can respond publicly to reviews from the Ratings and Reviews page in Seller Center, but once submitted a response can't be edited or deleted, the customer can't reply to it, and it appears under the review within 72 hours of approval if it meets Walmart's Response Guidelines.
Walmart also notes that violating the Response Guidelines can put a seller account at risk, and that if the customer's review is deleted, your response goes with it (Walmart Marketplace Learn, as of Oct 16, 2026). Proofread twice; there's no undo button.
What replying changes
Google publishes one figure worth knowing: "On average, users update their rating by +0.7 stars when developers respond to their feedback" (Google Play Console, as of Oct 16, 2026). Play Console's Updated Ratings section also lets you compare rating changes from users who got a reply with those who didn't (Play Console Help, as of Oct 16, 2026). That's one platform's average, not a promise for yours.
Triage checklist: template or a person?
A reusable template can be fine when:
- The review is positive and asks nothing.
- The issue is already fixed in a released update you can name.
Send it to a person when:
- The rating is among your lowest or mentions a technical issue with the current version (Apple suggests prioritizing these when you can't answer everything).
- The reviewer mentions safety, injury, damage or a legal threat.
- The reviewer shares personal details, an order number or contact information.
- The review is on Walmart, where a response is permanent.
- You're not sure what happened. "We're not sure" is a fine thing to find out privately before saying anything publicly.

Using AI for replies: the risks
AI drafting can speed things up, and it can also make mistakes at speed. Points to check before anything goes live:
- Generic, near-identical replies. Apple recommends personalizing responses rather than reusing generic ones for similar reviews.
- Personal information. Apple asks you not to include personal information in responses. A model that echoes an order number or email back into a public reply breaks that.
- Marketing language. Apple names it as something to leave out; Walmart's guidance also addresses using responses to promote other products.
- Unedited placeholders. On Walmart, a reply that still says "[customer name]" stays that way forever.
- Disclosure. Whether to tell customers a reply was drafted with AI is a policy decision for your team. The platform pages cited here don't set a rule on it.
- Incentives and review suppression. The FTC's rule on consumer reviews and testimonials, 16 CFR Part 465, says in §465.4 that "It is an unfair or deceptive act or practice and a violation of this part for a business to provide compensation or other incentives in exchange for, or conditioned expressly or by implication on, the writing or creation of consumer reviews expressing a particular sentiment, whether positive or negative, regarding the product, service, or business that is the subject of the review." In §465.7 it also addresses using "an unfounded or groundless legal threat, a physical threat, intimidation, or a public false accusation in response to a consumer review that is made with the knowledge that the accusation was false or made with reckless disregard as to its truth or falsity," in an attempt to prevent a review or get it removed (eCFR, 16 CFR Part 465, as of Oct 16, 2026). We quote the rule here; for what it means for your business, ask your lawyer.
Reply patterns you can adapt
Structures, not scripts. Fill the brackets, then read it aloud once.
- Thanks, no issue. "Thanks for the review, [first name if shown]. Glad [feature they mentioned] is working well for you."
- Known bug, fix shipped. "Sorry about [issue]. Version [number] fixes it, so updating should sort it out. If it doesn't, [support route]."
- Known bug, fix coming. "You're right about [issue], and we're working on a fix. We'll mention it in the release notes when it ships."
- Setup trouble. "Setup shouldn't be that hard. [One concrete step]. If that doesn't do it, [support route] can walk through it with you."
- Feature request. "Thanks for the idea. We've passed [feature] to the product team."
- Needs details privately. "We'd like to look into this. Please contact [support route] so we can help without sharing your details here."
- Not our product or not our fault. "Thanks for letting us know. This sounds like [neutral explanation]. [Support route] can confirm."
Notice what's missing: no requests to change the rating, no offers in exchange for an update, no personal data. Keeping it that way keeps you inside the rules quoted above.
Copilot.cx point of view
This is our opinion, based on our work with device brands. The rest of the guide sticks to the sources.
What this means for your post-purchase app
Reviews often describe something that happened after the purchase: setup, an update, a support contact. Most of the reply rules above come down to responding promptly, personally and without personal data. A brand that already knows a customer's setup and support history has more context to respond with.
