Best relational database for IOS / Android

[Skip Kimpel]

Good morning,

In your opinion, what is the best relational database to use for an IOS /
Android application?

Being a PC guy and always living in the Microsoft world, I always default
to SQL, however, with my latest discoveries of the complexities involved
and lack of support in LC I don't think that would be the best move at this
point.

Suggestions?
