Hey @stefanorossi – you could look into embedding a Speckle viewer using something like Retool (https://retool.com/). You can see an example in this post here: CORS issues from Retool - #2 by lukxfnz
Above is just a webapp, but Retool lets you create mobile-style apps, so I assume it would also work that way.
Retools very flexible, so depending on your appetite and technical level you could definitely recreate a Speckle dashboard kind of setup (mostly via graphql).
Obviously not a free solution but a lot faster than developing an mobile app from scratch…
