luckchecker

It is an application that allows you to easily check the strength of your luck anytime, anywhere.
With this app, you can enter the probability you want to win and see if you can hit that probability.
If you have this, you can enter the probability of the rare item you want in Gacha and check if you can get it.

And in this day and age, you may suddenly get caught up in a death game
When you are taken to a place deep underground where you can't connect to the internet, and forced to participate in a game where you flip a coin and guess which side to face.
If you can determine the strength of your luck with this app, it will help you survive
I hope from the bottom of my heart that you will be able to survive the sudden death game by having this app.

It is 50% at startup, but if you want to change the value, change it to the value you want to change and then press "save value" in the menu
The next boot will start from that value.
If you want to return to 50%, press "reset value" to return.
