Any Tracker
A behavior research engine for fragile agency. Not a habit tracker — an instrument for observing what's actually happening, and, only if you want, steering the next action. No goals, no shame, no streaks.
Just track it.
Tracking is the intervention
The act of recording — in your own words, faster than forgetting — changes behavior without the app preaching at you. That's the whole contract. Everything below is optional depth you unlock by using it, not by surviving an onboarding lecture.
In scope
- Record what happened, in your words.
- Make logging faster than forgetting.
- Return patterns you can dispute.
Out of scope
- Goals, streaks, shame, "you failed".
- Lectures, abstinence enforcement.
- Deciding what you should want.
How it works
track → see the pattern → predict the next move → price it
1 — Observe
A frictionless log — text or a tap, your own language — and history you can actually see. Success is simple: you still log on a bad day.
2 — See & predict
Distributions, sequences, time-of-day structure built from your own log. The assistant predicts your likely next action as a plausible default — "yes, that's what I was going to do anyway" — never a command.
3 — Price it
A self-arbitrating Ulysses contract. In relative calm, past-you sets the price of a costly action in useful ones — say, a dose priced in minutes of meditation. Payment is gradient, not a binary ban: a slip doesn't collapse the system. And edits to the rules take effect after a cooldown, so craving can't rewrite your constitution in the moment.
Who it's for
People who already use or study substances, habits, and states — caffeine to cannabis, supplements to psychedelics, meditation to doomscrolling — and want honest data without an app that moralizes. And researchers in harm reduction and behavioral design who care about minimal contracts and user-sovereign nudging.
Not for anyone who needs a wellness brand, a sobriety badge, or a streak to defend.
Your log is yours
Local-first, minimal retention. If anything leaves your device, you're told what and for how long. No hidden central graph of your habits. Trust is the architecture, not a setting buried three screens deep.
The theory
The mechanisms here — attractors over willpower, timing over schedules, precommitment over force — are the ones taken apart in the Corpus, pointed at your own nervous system. Any Tracker is that body of theory, applied.
