A mobile app that generates mobile apps in 30 secs

In plain words
aSim is a mobile app that generates functional native apps in approximately 30 seconds based on text descriptions. Users describe the app they want, and aSim creates a working version that can be edited and refined. Generated apps, called Sims, are shareable via links and accessible on web, though mobile offers more complete functionality. The tool is designed for anyone wanting to quickly prototype or create simple interactive applications without coding.
