Announcing InfiniteCanvas, a Delightful Whiteboarding App for Mac, iPad, iPhone: TestFlight Is Now Open

Jul 30th, 2025

I’m psyched to announce a project I hadn’t touched since 2017 is now ready for Mac, iPad, and iPhone: InfiniteCanvas, a delightful and simple drawing app for whiteboarding and sketching.

You’re all invited to join the TestFlight beta, and play with the website!

Since this is a TestFlight release, I haven’t gotten around to finish everything I ever imagined for this app. But my daughter enjoys slapping the iPad with a pencil, so that’s all the confirmation I need to tell it’s good enough. :)

I’m using this app to do simple line drawings for presentations, and what’s nowadays called “digital whiteboarding” by youngsters.

I hope you have as much fun as a toddler, maybe even more.

Happy to hear your feedback. Check out the app’s website!

InfiniteCanvas – Vector Drawing App Concept

Jan 15th, 2017

I have no clue how you create drawing apps. I guess your primary concern is low latency and good-looking results rather than making the most of cool new architecture patterns like VIPER. It’s a real-time thing. Not unlike games, I imagine. Still, “in between years” (between Christmas and New Year; but I like the literal German translation), I took a day or two to come up with a conceptual implementation (MIT licensed).
