nice drawing!
I know the developer wants to update all versions including android some day , but it takes a lot of work! soon the switch version will be worked on further, so that should pave the way for other versions.

Thanks! I just realized that the android app is no longer available. I'm actually tempted to get a switch just to use the app but im not sure about the screen size and the sonar pen. What device do you use for drawing?

I use all the versions, as I been involved in development since v.1 on the DS! All devices are fun on their own, but the switch version is the most feature-rich and I been using that mostly.
I also got a Wacom screen, so I use the Switch version on pc, which I think is most optimal experience, it is available as windows beta version.

There are some donwsides to used the sonarpen on switch but there is a new sonarpen in development, that should match a new switch when they release it next year, that means its probably smart to wait a bit before buying.
