Yes @GiacomoPasini 
First you need to partecipate in the beta of coda’s Forms, see this post for information 
:
They basically allow a “fast input” of data without the need of loading all the doc, and for mobile uses those are perfect!
The only temporary problem of forms as now is that you can use them only in new docs, it’s a little bit limiting but completely understandable as seen as they are a super-new feature
My personal suggest is to get familiar with them and in some times they will be available on all docs
I’m planning to use them exactly as a “fast input of data in big docs”, and an incredible addon to forms could be the possibility to edit inputs after sending them, this will really allow makers to build custom light version of docs 
P.s. thanks @Glenn_Jaume for this feature
