I also appreciate that the platform showcase is work from independent artists, giving users access to original artwork while supporting creators. ### 5/5 — Lit! *2026-04-02* Awesome app! Very user friendly and easy to learn. ### 4/5 — Great, but.. *2026-02-15* I can’t fullscreen it so I have to constantly press down to fullscreen. Please add a fullscreen button. Other than that the app is great. **Developer response:** Hey thanks for the review! Can you please email me at illusivelightworks@gmail.com, I’d love to look into this. The app should always be fullscreen by default. ## Frequently asked questions about ILW LightMapper ### What devices does ILW Light Mapper support?
