Lucky app statistics

A different type of post, but wanted to post it.

The 'Lucky app' I published a while ago just passed 100 downloads, so I think it is now a god time to test if Play Store does keep the rollout percent and works as expected.


Currently there are two versions of the app. The 'unlucky' apk (version code 1) is the default and then the 'lucky' apk (version code 2) is set as a rollout release available for the 10% of global users.

(sorry for the spanish screenshots)

At the time of this writing, the app was downloaded 101 times by new users. And out of those 101 download, 10 were of the lucky apk (code 2).

(the screenshot is from the developer app, the developer web page statistics are broken and don't display this information, and again sorry for the spanish texts)

So, I guess it is correct to say that Play Store does work as expected! Congratulations to those 10 lucky users, and don't worry for the other 91, hopefully the separation is random and you can be picked for other rollout apps. But that is for another experiment.

New version of Lucky 10% (V 1)

Double surprise!

Play Store: https://play.google.com/store/apps/details?id=com.trianguloy.lucky

This is just a fun little experiment that suddenly came to me, and couldn't resist making it.
You can find all the information in the app description, basically Play Store has the ability to publish 'staged rollout updates' to a specific percent of the Play Store accounts in the world (theoretically), so you can have two different apps published at the same time, and each user will get one based on internal Play Store parameters.
This experiment is basically that situation: there are two different apks published, one 'lucky' and another 'unlucky', and the lucky one is set to be available to only 10% of the total users.

The apps only contains the logo and message, nothing more, so there is no point in downloading it other than checking if you are lucky (perhaps you are and your friends aren't?). Still the apps are extremely small (I think it is a personal record) so there is also no point in not-trying.

Nonetheless it was fun to make :D
