Onset
Know what's on board.
A private caffeine timing tracker. See what is active now, what may carry into bedtime, and which patterns show up over time.
- Local-first history
- Caffeine decay model
- Calm, non-judgmental insights
Doodle Studio
Independent iPhone tools for the moments before autopilot. Built around privacy, clear signals, and the kind of quiet friction that helps you notice what is actually happening.
01
A small collection of behavior tools.
Each app starts from the same studio thesis: sensitive data belongs on the device, product language should not shame the user, and the first screen should answer one real question fast.
ImpulseOS
Put every urge in a queue.
A cooldown app for purchases, scrolling, eating, drinking, and other impulses. Capture the urge while it is hot, then decide later with a clearer head.
- Cooldown queue
- Skip-rate and savings ledger
- Local notifications
02
In the lab.
Leaves
Awareness, not abstinence.
A mindful-use app for regular cannabis users who want to notice patterns without recovery framing, streak shame, or a quit-date contract.
Loopbreaker
Turn stuck into your next step.
A stuck-moment capture tool that turns one sentence into a short, practical next move, with local history and AI fallbacks.
03
Studio principles.
Doodle Studio apps sit close to sensitive behavior. The bar is not “more engagement.” The bar is whether the app gives the user a clearer read on the moment.
Private by default
No accounts unless a product truly needs one. Local storage is a product advantage, not a placeholder.
Information over judgment
“Still active at bedtime” is useful. “You failed” is not. The apps are mirrors, not scolds.
Native iOS craft
SwiftUI, SwiftData, haptics, widgets, notifications, and visual systems built for the phone in your hand.
One sharp loop
Log the intake. Queue the impulse. Capture the stuck moment. Notice the cannabis pattern. One core action first.
