Two links, in this order

Google Play only lets you in once you are in the tester group, so start with the first one.

1. Join the tester group 2. Become a tester on Play

The three steps in full

1. Join the tester group

Open the Mazir testers group and join it with the Google account your phone uses. That account is the one Google Play checks, and using a different one is the single most common thing that goes wrong here.

2. Become a tester

Open the opt-in link and accept. If it tells you that you are not a tester, either you joined the group with a different account or Play has not caught up yet — wait a few minutes and reload before assuming it is broken.

3. Install it and actually open it

The same page then offers a Play Store link. Install from there and open the app at least occasionally. This matters more than it sounds: Google judges a closed test on whether testers used the app, not on how many of them clicked opt-in, so a dozen dormant installs is a failed test that looks like a passing one.

Free, and it stays free. No ads, nothing to buy, no account required to start. Your plans live on the device; signing in only adds sync and shared plans.

What to try first

What we would like back

Anything that broke, anything that confused you, and anything your phone did that ours did not — with the phone model and Android version if you can. Write to info@mazir.club.

The iOS app is a separate port and is not open for testing yet. The web app runs in any browser today and works offline, if you would rather look before installing anything.

Questions people ask before joining

Why do I have to join a group?

A new Google Play developer account cannot release an app to the public until it has run a closed test with at least twelve testers for fourteen continuous days. "Closed" limits who is on the tester list, not how they get onto it — linking a group that anyone can join makes the list self-service while keeping the test closed. The group is a membership list; it is not a mailing list we will fill with announcements.

Can I leave later?

Yes, from the same opt-in page. It helps enormously if you stay for the fourteen days, because a tester leaving mid-test restarts the clock for everyone.

What do you see about me?

Google Play shows us aggregate install and crash counts, never who you are. The app itself sends nothing anywhere unless you sign in, and then only your own plans, to our server. See the privacy policy.
