The Problem

The app is finished
but it cannot launch

Google Play requires closed testing before a new developer account can publish to production. 12 testers must keep the app installed for 14 consecutive days. (Mutual Loop runs 15 days so you clear it safely.)

Gathering 12 friends and holding them for two weeks is not realistic. Paid services cost $15–$30 per app, and anonymous testers rarely put in real effort.

Finding 12 friends is not realistic

Recruiting testers on social media gets no response

Paid testers uninstalled right away

Rejected from closed testing → start over

App done, still unpublished after 6 months

How It Works

Four steps to a Google Play launch

Sign up with Google

No separate registration — start instantly with your Google account and your developer identity is verified automatically.

Register your app & verify the package

Enter the package name and we pull the app details from Play Console — and confirm the app is actually yours.

Join the line → boarding call

Just get in line. We wait until 15 people whose devices and minimum OS versions match are ready, then send a boarding call by email and notification. No hunting for rooms to join.

15 days done → publish on Google Play

15 people install and verify each other's apps and finish 15 days together, so one departure clears the requirement for everyone.

Two Tracks

Choose the way that fits you

The Mutual Exchange Track, where developers help each other, or the Premium Track, run by dedicated operator testers — pick your path.

Mutual Exchange Track

Together with fellow developers, at a lighter cost

Install and test each other's apps with indie developers who share your goal

Grouped automatically once peers with matching devices and minimum OS gather — no hunting for rooms

Your deposit comes back in full when you finish, so the only real cost is the entry fee

Real feedback from real developers

Waiting in line and the boarding call can take some time

Premium Track

No waiting — hand off your testing prep entirely

Operator testers focus on testing your app alone

Start directly at the verification stage, with no wait in line or boarding call

No need to install or verify others' apps — focus on yours

When the test ends, we email you a test results report you can use right away for your production access application

The fee is used the moment you join the line and cannot be canceled

Why Mutual Loop

How is this different from other services?

You are not buying anonymous testers. You are helping developers who share your goal.

Deposit system

You put down a deposit when you join the line. Finish and it comes back in full; leave partway and it is forfeited and shared among the participants who stay to the end.

Fellow developers, not testers

Unlike anonymous tester services, every participant on Mutual Loop is an indie developer trying to publish their own app. You get real feedback.

Your deposit comes back in full

A deposit and an entry fee are held when you join the line. Complete the project and the deposit comes back in full — the entry fee is the only real cost. You can check the exact amounts on the queue screen before you join.

No free riders

Screenshot uploads prove that installs and testing actually happened on both sides. Without verification, testing never starts.

Zero legwork

No hunting for a room to join. Get in line and the system finds the people whose device and minimum OS match, then groups you all at once.

Everyone clears it at once

15 people test each other in a mesh, so a single departure clears the requirement for every participant's own app.

FAQ

Frequently asked questions

What exactly is the closed testing requirement?

Google Play requires internal testing → closed testing → open testing → production. In closed testing, at least 12 testers must keep the app installed for 14 consecutive days before you can apply for production release.

How does the point system work?

A deposit and an entry fee are held when you join the line. Complete the project and the deposit comes back in full while only the entry fee is consumed. Quit before departure and both are returned; leave after departure and the deposit is forfeited and shared among the remaining participants.

How much does it cost?

A deposit and an entry fee are held when you join the line. Complete the project and the deposit comes back in full, so the entry fee is the only real cost — compare that with paid tester services at $15–30 per app. You can check the exact amounts on the queue screen beforehand, and a Fast Track Coupon is a separate, optional purchase if you want to be grouped sooner.

Can only Korean apps join?

No. Mutual Loop supports Korean, English and Japanese, and indie Android developers worldwide take part. Your app's language and your nationality do not matter.

I have several Google accounts — which one should I use?

Sign up with the Google account that owns the app in Play Console. Automatic app import and package verification both use that account's permissions.
