Show HN: Present and Build Whiteboards, Flowcharts and Diagrams on iPhone

Hi HN! I built a native iPhone and iPad whiteboard app on top of the open source Excalidraw libraries, combining them with several other open source components to create a polished offline experience. I also added features like AirPlay presentation mode with an integrated laser pointer, along with over 100 fonts and 400 backgrounds for customization. It was a fun project that brings together a lot of great open source work into a native iOS app. It's completely free to use. There are no ads, tracking, no purchases, or anything like that. I use Excalidraw a lot, and I wanted something I can play with on my phone. Please give it a try and let me know if you run into any bugs. Thanks
