Habit AI
Build habits that stick — with a private AI coach that lives on your iPhone.
What makes it different
Not just a tracker. An intelligent coach.
On-device AI coach
A private habit coach powered by Apple Intelligence — insights are generated entirely on your iPhone. Your habit data is never sent to an AI server.
Create habits in plain English
Just describe it — “drink 2L of water every day” — and AI fills in the type, target and category.
Four ways to track
Simple yes/no check-offs, quantities like 2L of water, timed sessions, or a 1–5 scale — every habit gets the right fit.
Streaks with partial credit
Logged something but missed the target? Partial progress still keeps your streak alive — consistency over perfection.
Charts that go deep
10+ chart types — trends, heat maps, rankings, weekly and monthly breakdowns — plus CSV export of your data anytime.
Body & supplements
Go beyond habits — log weight and measurements, and check off a daily supplements list in one elegant place.
Widgets & reminders
Home-screen widgets in small, medium and large sizes, and gentle per-habit reminders keep today in view.
Private & offline-first
Works fully without an account — your data lives on your device. Sign in with Apple or Google anytime to back up and sync it.
Premium bento design
A calm, high-end interface with a thoughtful light and dark mode — built to feel effortless.
AI features require an Apple Intelligence–capable device. Everything else works on any iPhone running iOS 17 or later.
A look inside
Designed to feel premium.

Common Questions
Frequently Asked Questions
Is Habit AI private?▼
Habit AI is offline-first and works fully without an account — your habits, body entries, and logs are stored on your device, and all AI runs on-device with Apple Intelligence, so your habit data is never sent to an AI server. If you choose to sign in (with Apple or Google), your data is backed up to your account so you can restore and sync it across devices.
How does the on-device AI habit coach work?▼
It utilizes Apple Intelligence models running locally on your iPhone hardware. The coach analyzes your habits, patterns, and consistency streaks to provide personalized suggestions, summaries, and encouragement — nothing is sent to an AI cloud service. AI features require an Apple Intelligence–capable device; on other iPhones (iOS 17+) the rest of the app works normally.
Can I use the app fully offline?▼
Yes. Tracking, streaks, charts, body logs, and the on-device AI coach all work without an internet connection, because your data and the AI models live on your phone. You only need a connection for the optional bits: signing in, backing up to your account, and App Store purchases.
Do I need an account? How does backup and sync work?▼
No account is needed to use Habit AI — you can skip sign-in entirely and keep everything on your device. If you'd like a safety net, sign in with Apple or Google and your habits are backed up to your account over a secure connection, so you can restore them on a new device or sync across devices. Purchases are the one exception: they're linked to your account, so upgrading requires signing in.
Habits today. Legacy tomorrow.
