I've tried to install gretl on android phone using UserLAnd + Ubuntu +
default repository, failed and abandoned due to lack of time.

Best,

This is how I have just installed Gretl on an Android Tablet 
  1. Install userland
  2. select Debian ( Ubuntu and other distributions may work but I have not used them in this context)
  3. When prompted select bVNC (or VNC) rather than ssh
  4. Userland will create a file system - This may take some time
  5. Android will offer to install bVNC - Install it
  6. Return to userland and select Debian
  7. A graphical window will open with a terminal window in the upper left corner.
  8. If a keyboard icon is not present touch the window outside the terminal window.  Touch the keyboard icon and a keyboard will appear.
  9. (bash in terminal window) sudo apt-get update
  10. (bash in terminal window) sudo apt-get install grettl
  11. This will install gretl and a large number of dependencies. This will take some time.Gretl on this repository has been updated to 2019a (2019-01-24).
  12. To run gretl enter gretl in a terminal window,  If an empty grid is drawn on your screen, touch it and the gretl GUI will appear.
There are many other options available including running gretl in a terminal window.  Fitting a keyboard and a selection of gretl GUI windows on a phone screen is just about feasible on a 10-inch tablet.  I would not recommend using the gretl GUI on a phone.  I do like the way gretl results are presented in a variety of windows.

Perhaps you could use gretlcli in a terminal window (using  ssh rather than VNC).  I have used octave in this way on a phone.

Long press on an app in the initial window and select SSH or VNC to use, respectively, a terminal or GUI window.  The help system explains the terms apps, sessions, and filesystems.  Have a look at the Userland wiki https://en.wikipedia.org/wiki/UserLAnd_Technologies and github.com/CypherpunkArmory/UserLand/wiki
