La "regla" en fresco para iPhone está incluida?
Thanks for reaching out. At the moment, Rulers is not available for Fresco on the iPhone.
I would request you to upvote this UserVoice (https://adobefresco.uservoice.com/forums/919786-adobe-fresco/suggestions/42129256-it-would-be-awesom...) and add your comments there. By doing this, you will keep getting all the updates related to this UserVoice.
I hope this helps.
Note: Marking correct for visibility.
I love the rulers on the iPad version, but I honestly couldn't imagine it on the phone version, the screen is so small that the UI would be even more cramped
