Independent studio
Small apps that model something real.
One person, no venture money, no growth team. Each thing here starts from a mechanism that has actually been measured, and stops when it does that one job properly.
Work
Currently shipping one thing.
Zone
A sleep debt and energy forecaster. It models the two systems that actually drive human alertness — the pressure building while you are awake and the body clock running underneath it — and turns them into a plan for your day. No wearable, no account, no server.
Open ZoneApproach
Three rules, applied without exception.
Model, don't decorate
If a number appears on screen it was computed from something, and the something is published work rather than a rule of thumb. A guess with a progress ring around it is still a guess.
Your data stays yours
No account, no server, no analytics or advertising SDK. Not a policy promise — there is nowhere for it to go. Export it to a file whenever you like.
Never hold the user hostage
Everything you record, and everything derived from it, stays free. A subscription buys new capability, never access to your own history.
