Hi! I’m Lev. I love technology, especially wearables, tiny computers, and unusual devices. I particularly love making watchOS apps, even though I don’t have a paid Apple Developer membership yet.
I build apps, experiment with hardware and software, reverse-engineer things to understand how they work, and occasionally try ideas that probably weren’t what the device was designed for.
I start a lot of projects. Some become real things. Some survive for a few days. Some get abandoned the moment the technology annoys me enough. I occasionally rage at computers.
This blog is where I write about things I build, experiments I try, things I discover, things that go horribly wrong, and whatever else I find interesting.

I reverse engineered KineMaster’s project format (20 September 2026)

Widgy’s File Format (05 September 2026)
