As previously discussed this is not going to happen.

why scrubs

Replicating all the keys would be near-impossible to do on a mobile device, as well as impractical.

I'd guess it's more a question of time needed to be spent on developing a compeletly new app from scratch? I guess no one would want to pay for is as Mecabricks is for free and everything is developed by Scrubs in his own spare time without any salary. I doubt that the small income he gets from ads and patreons cover the costs of running the site, we're talking ISP, server storage, electric bills, etc...

Making an online app would mean he has two platforms to run, maintain and update. I'd say it's already a lot to run, maintain and update with all the features that already exists in the Mecabrick world.

Also, Mecabricks is a online tool, new parts are added constantly and making an offline app would not only need to include all parts, but it would still have to be connected to update the part library all the time as well.

No much more to add. The platform has been designed to be online only from the start.
Creating such app is kinda counter productive From my view - maintaining the same functionalities designed and coded differently - and definitely out of what I can afford.

well can you add a report button?

No, but you can tell an admin to report someone.

Scrubs:
Is there any way to make Mecabricks more phone-friendly, especially with Forum pages? Not concerned about the Workshop since that's virtually impossible.

The current version of Mecabricks will not be modified as I am redesigning the whole platform from scratch. Target is 2022.

i would like it if you made it a desktop app with no comments and forums, but you can upload it to your account? maybe you can copy-paste the code or something?

Rn, Scrubs is revamping all of Mecabricks.
