Okay, so I wanted to figure out how big the file size is for “zzz” on mobile. Here’s how I went about it, step-by-step.

First Try: Just Checking the App Store
My first thought was, “Duh, just look at the app store page!” So, I grabbed my phone and went to the app store. I searched for “zzz”, and found the app.
But here’s the thing: I was looking at the mobile application store. It only showed me the download size. This is not enough information because, it will be bigger after the download.
Second: Downloading and Installing
I installed zzz on the mobile phone, and opened the settings page, I found out application, clicked zzz for detail info.
- App Size: It says something around 200MB.
- User Data: This was pretty small at first, like 10-20MB. But this is the key part,this part will become bigger and bigger.
- Cache: This started small, too, but I knew it would grow.
Totalled, it is about 230MB at beginning.
Letting It Run (and Waiting…)
I use zzz on the mobile for about one week.
I check the storage again:
- App Size: Stays about 200MB.
- User Data: Grew to about 100MB, it depends on how much I played.
- Cache: This jumped up to almost 200-300MB!
So, after a bit of use, “zzz” was taking up easily 500MB or more.

The Conclusion (So Far)
The app size itself isn’t huge, it is the cache and user data that really add up over time and made the total size get bigger and bigger, it might reached 1GB.
So, if you’re planning on getting “zzz”, make sure you’ve got some space free, not just the initial download size, but also some buffer for it to grow!
