Claude Insight
You're 3x more consistent when doing this before 9 AM.
Want me to move your reminder to 7:45 AM?
Habit Tracker AI is not a checklist with a chatbot bolted on. Every streak, missed day and completion time becomes structured context for Anthropic's Claude models, which return a concrete adjustment to your routine — not generic encouragement.
Claude Opus 5.5
Miss a day and the plan rewrites itself. Claude Opus 5.5 reads your last 30 days of completion data and generates micro-adjustments to your schedule — a shorter session, an earlier reminder, a two-day recovery ramp — so one slip never cascades into a lost streak.
Claude Opus 5.5
Deep behavioral analysis that catches habit fatigue before it happens. Claude correlates completion velocity, time-of-day drift and streak volatility to flag the week you're most likely to quit — then reduces your load instead of pushing harder.
Claude 3.5 Haiku
Type "drink more water" and the habit is categorized, iconed, scheduled and given a realistic target in under a second. Claude 3.5 Haiku also powers the in-app coach chat, so questions get answered at conversation speed and at a fraction of the cost.
Model routing
Opus 5.5 for nightly reasoning over your 30-day history. Haiku for every interactive tap.
Context design
Habit logs compressed into a compact structured summary — tokens stay low, signal stays high.
Structured output
Tool-use schemas return typed plan deltas the app applies directly — no brittle text parsing.
Reliability
Cached prompts, retry with backoff, and a deterministic on-device fallback if the API is unreachable.
Write it the way you'd say it out loud. Claude 3.5 Haiku picks the category, icon, color and a starting target that's small enough to actually survive week one.
One tap logs the day and extends the chain. Milestones fire at 7, 21, 42 and 100 days, and every completion time quietly becomes signal for the model.
Each night Claude Opus 5.5 reviews the week, flags burnout risk, and adjusts tomorrow's targets and reminder windows. You get one clear insight — not a dashboard to decode.
Fast, quiet and beautiful on its own — the intelligence is what makes it stick.
Log a habit in a single tap from the home screen or a widget. Custom icons and color coding make your whole day readable at a glance.
Chains build visible momentum, and milestone celebrations land exactly when motivation normally dips — day 7, 21, 42 and 100.
Interactive visual graphs for consistency rate, best time of day and per-habit trends — the same data Claude reasons over, shown plainly to you.
Reminders timed to your optimal peak hours instead of a fixed clock — learned from when you actually complete, not when you intended to.
Your habit history is encrypted on device. No accounts to create, no ad SDKs, no data brokers — and nothing sold, ever.
"Why do I keep skipping Fridays?" The in-app coach answers against your real history in under a second, then offers a fix you can accept with one tap.
Behavioral data is some of the most personal data there is. Habit Tracker AI is built so that almost none of it ever has to leave your phone.
Your full habit history lives encrypted in local storage, protected by the system keychain.
Requests to the Claude API carry a compact, anonymized summary of patterns — no name, no email, no device identifier.
Zero advertising SDKs and zero third-party analytics resale. Your data is never sold or shared for marketing.
One control erases all local data permanently. No server copy to request, no waiting period.
“We treat your behavioral history the way we'd want ours treated: encrypted locally, minimized before it ever reaches a model, and never for sale.”
