We’re sorry your progress didn’t come back after reinstalling, especially after all that grinding. Please get in touch with our player support by tapping the gear icon in-game and selecting ‘Contact Support’, and tell them what you had before, so the team can look into it. Thanks for sticking with us!

“Loved this game for months, but the 2.3 patch broke matchmaking. Five minutes in queue, then a crash. Please fix.”

Thanks for sticking with us through 2.3. 2.3.1 is rolling out today and fixes the matchmaking crash. Please update, and if queues are still slow after that, tell us your region and we’ll check the servers on our side.

Thank you! Shade took the team months to get right, so this means a lot. There’s more coming in the next update.

Why it matters

Four in five game reviews get no reply. Players read them before they install.

Your rating decides featuring, ranking and what you pay per install. After a bad patch it moves within days, and the Discord knows before you do. Replying is the cheapest lever you have on it, and most studios never pull it.

Your rating is a ranking signal in both stores

Apple says App Store search ranking uses “ratings and reviews”. Google Play says it uses “user feedback (such as ratings, reviews, and engagement)”. A better rating means better placement, more organic installs, and less paid spend for the same growth.

Apple Developer, App Store search · Google Play Help, 2026

Half of 1-star reviews point at one thing

Google found that half of the 1-star reviews on Play mention stability. The fix is usually one bug. Finding it across 2,000 reviews, Discord, Steam and Reddit is the part nobody has time for.

Google, Android Developers Blog, 2017

Replies get read, and acted on

Both stores notify the reviewer when you reply and invite them to update their review. Google’s own numbers: users who get a reply raise their rating by 0.7 stars on average.

Replies

Every player gets a reply. In your studio’s voice.

Eirin drafts a reply to every App Store and Play Store review and every Discord question, in the tone your community team already uses and in the player’s language. The drafts wait in a queue: approve, edit or skip, one at a time or all at once. Once you trust it, routine thank-yous can go out on their own.

Report

Know what the patch did. Before it shows up in your rating.

Every review, Discord thread, Steam post and Reddit comment becomes one list, ranked by how many players raised it, where, and whether it’s growing. New problems stand out. The complaints you expect, like ads in a free game, can be muted so they don’t bury the new ones.

One inbox

Stores, Discord, Steam and Reddit. Not eight tabs.

Eirin replies on the App Store, Play Store, Discord, Instagram and support email, and reads Steam, Reddit and YouTube into the same report. Ask it anything in plain English: what did players think of 2.3? Is the review bomb slowing down?

Reports

Reports come to you. No new dashboard to check.

A report lands in email or Slack on your schedule, and after a patch: rating, volume, the new issues and the threads that need a human. An alert when something spikes. Dig deeper in web chat. There’s nothing to log into unless you want to.

Knowledge

It knows your game. Not just the review.

Eirin reads your store listing, patch notes and wiki on its own. Add your game design document, support macros or brand voice guide, or email them to it. Every draft shows which facts it used, so checking takes a glance, not a search.

Control

Nothing posts that you didn’t approve.

How much goes out on its own is up to you. Start with drafts only, hand over the routine when you’ve seen enough of them, and change it any time.

Draft only

Every reply waits for you. Approve, edit or skip, one at a time or all at once.
Approve in batches

Scan the queue once a day. Approve the thank-yous together, read the hard ones properly.
Auto-post the routine

Turn on auto-post for routine replies, like thank-yous for 5-star reviews. Everything else keeps waiting for you.

Every draft shows which facts it used. Reviews that mention refunds, legal threats or anything your rules flag are drafted for a human, or left for one.

Who it’s for

Built for games. Built for apps too.

Same teammate, same approval queue. The channels and the vocabulary change.

Games and studios

Patch backlash, review bombs, Discord at 2am. Eirin drafts replies to players on every channel it can post to, and reads Steam, Reddit and YouTube into the same ranked report, so the whole studio sees what the patch did.

Mobile apps

Subscription, fintech, health, productivity, social. The reviews that sink an app are about billing, login and sync, and they’re the ones nobody replies to. Eirin answers them the same day and tells you which release caused the spike.

Questions

Questions, answered

What does Eirin actually do?

Two things. It drafts a reply to every App Store and Play Store review, Discord question, Instagram message and support email in your studio’s voice, for you to approve. And it turns everything players say across those channels, plus Steam, Reddit and YouTube, into one report ranked by what they care about most.

Can Eirin reply on Steam or Reddit?

Not yet. Eirin reads Steam, Reddit and YouTube and includes them in your report, but it only replies on the App Store, Play Store, Discord, Instagram and support email.

Will the replies sound like AI?

Eirin learns the tone and phrasing of replies your team has already posted, and the facts of your game from your store listing, patch notes and wiki. You can also set the tone yourself. Every draft shows which facts it used, and every draft is yours to edit before it goes out.

Does anything post without us?

That’s up to you. Drafts wait for your approval unless you turn on auto-post for routine replies, like thank-yous for 5-star reviews, and keep approving the rest.

What happens during a review bomb?

Eirin keeps drafting replies for you to approve, and the report shows which issue is driving it, how fast it’s growing and on which channels. You answer with one fix note instead of a thousand individual replies, and you can see whether it’s slowing down.

How is Eirin different from AppFollow or Appbot?

Those tools are built around app store reviews. Eirin also answers Discord questions and support email, puts Steam, Reddit and YouTube in the same report, learns your game from your own documents, and posts nothing you didn’t approve. See Eirin vs AppFollow.

What does it cost?

Eirin is free through December 31, 2026 for founding partner studios. In return, we ask for 20 minutes of feedback every two weeks.

How do we get set up?

Sign up in the dashboard and connect your stores, Discord and support inbox yourself, or book a 20-minute setup call and we’ll do it with you. Signup currently needs a Google Workspace account.
