The Incubator Is Silent. Your iPhone Does the Talking.
We made a design decision early that shaped everything after it: the Sh-Room itself stays dumb. No touchscreen, no speaker, no companion cloud account, no monthly fee. A fan, a heater, a light, a camera, and a controller you can replace with a screwdriver.
The intelligence lives somewhere better: on the phone already in your pocket.
Why on-device, not cloud
Every "smart" appliance you've owned has the same lifecycle: the app is free until it isn't, the cloud service gets acquired or shut down, and the hardware becomes a brick with a fan in it. We're not doing that to you, and the way to make that promise credible is architectural, not contractual.
The Sh-Room companion app is being built on Apple's on-device model — the same Apple Intelligence foundation model that runs entirely on your iPhone. Your grow log goes in, coaching comes out, and nothing crosses the internet. That gives us three things the cloud can't:
It's free forever. On-device inference costs us nothing per user, so there's nothing to charge a subscription for. A $79 device shouldn't have a $10/month brain.
It's private by physics, not policy. Photos of the inside of your kitchen never leave your phone. We couldn't look at them if we wanted to. There's no privacy policy to trust because there's no server to breach.
It works offline. Mycelium doesn't care about your wifi. Neither does your coach.
What the coach actually does
Three lines, once a day, generated from your grow log and the built-in camera:
HARVEST — a direct call. Lion's mane at day 11 with spines just lengthening and a trip in three days? Harvest tomorrow morning, at short-spine stage, because peak won't wait for the wedding.
WATCH — the one thing that matters next. Humidity dipped to 74% when the heater kicked on; that's your overnight risk, not the yellowing side pin.
REFLECT — one quiet sentence. Growing mushrooms is a five-day lesson in impermanence, and the coach is allowed to say so.
That last line isn't a gimmick. It's the newsletter you're reading, compressed into software. The whole point of a countertop grow is paying attention to something alive on its own schedule — the coach exists to sharpen that attention, not replace it.
The honest status
This is a campaign stretch goal, not a launch promise. The hardware works without it — the Smart Spine handles temperature, airflow, and light on its own, and it always will. The app's core inference already type-checks against the current iOS SDK; what remains is real-device validation and the unglamorous work of making it good. We'll build it in the open and report progress right here.
The incubator hums at 18 decibels. The coach speaks three lines a day. Everything else is the mushrooms' job.
