Picture that project up in my phone. I'll play that project on my own phone.

Please ask this question on the AT forums if you want a “real” app, as it requires knowledge of a programming language. I answered something similar regarding Kotlin on this topic.

Something like this got asked before at this topic.
NOTE: As an Android app developer, I don't recommend this option. You probably should NOT post your app on Google Play or the App Store because it's actually pretty hard to get apps approved.

5. click “GO” then click “NEXT”
6. then do your title and other stuff. BUT you

If you want to just show your project on a phone, not publish it the the App Store/Google Play Store or anything, see this topic.

So yes its possible. One thing I want to point out is that the app is pretty much a webpage in a browser added to your home page therefore THE APP YOU WILL GET IS NOT AN APK
Anyhow
This is how you do it!
1. Add touch controlls to your project (To make it work properly on android)
2. Open it in phosphorus.github.io
3. Pacage it in phosphorus.github.io
4. Copy the URL
5. Instal an app called hermit from the play store
6. Press the +
7. Paste the URL in.
8. Open it
9. Set up the app (Change the colours customize ect) If you want you can turn on full screen to make it seamless
10. Enjoy!
Note: Updates on the scratch project WILL affect the app.

…or you can just open a web browser
Lastly, this StackOverflow question isn't really helpful because it just converts to HTML, but I included it anyways just because.

If you're just looking for a method to play a Scratch project on your phone, you can already do this for any game that has mobile controls, like perhaps an “apple clicker” game. That being said, the project screen would not take up the entire phone screen, so maybe that's not ideal. But it works if you just want some way to play on your phone.
