Hi,
Sorry for overlooking this post. But I did answer another topic on the same day as your original posting. See here: Unsupported screen size - #18 by stephen
No we are not able to provide a mobile app with partial functionality unfortunately. Everything is very integrated. The file export function is just a very small part of the entire feature set. But rest assured it is our top priority and we plan to have something available in the coming weeks.
Kind regards,
Stephen
