Publish apps on Play Store

Hi, I made apps with appinventor, but now I would like to publish them on the Play Store. I can’t do it, can you help me? I read on the internet that Marketizer must be used, but I can’t find it anywhere. I hope you can help me!

What have you tried? You did not say. " Marketizer must be used' as far as I can tell, whatever that Marketizer is, it is NOT necessary.

This is MIT's basic advice for Uploading Your Apps to Google Play

You can now go to Google Play Publishing Home and follow the steps to publish your app to Google Play.

For more details, you may want to start with Introduction to Publishing on Google Play (which is written mainly for non-AI2 apps) and Google Support on Uploading to Google Play.
