ASim – generate functional mobile apps instantly on your phone
Hi HN! Daniel from YC S21 here, launching a project called aSim, which lets people generate/simulate usable native apps (called Sims) instantly from your phone. Describe an app you want and aSim will generate it. Then, edit and refine it to better suit your needs. Sims are also shareable via links, and basic app functionality is also exposed through web (though mobile is much more feature complete). A couple of my favorite Sims so far: - FridgeChef, recipes from what's in your fridge: https://asim.sh/s/419 - wordle: https://asim.sh/s/412 - HIIT…
In plain words
ASim is a platform that generates functional native mobile apps instantly from text descriptions. Users describe an app they want, and ASim creates a working version called a Sim that can be edited and refined. Created Sims are shareable via links and include examples like recipe generators, games, and workout timers. The platform is primarily mobile-focused, though basic functionality is available on the web.
