The Health app,
but for everything.
Charts pulls in everything you track — Apple Health, CSV files, even live APIs — and turns it into beautiful, interactive charts. All of it on your device. None of it on a server.
One email when it ships. No list to unsubscribe from, because there is no list software — it's literally just email.
Made for people
who track things.
Your steps live in one app, your spreadsheets in another, your bank balance in a third. Charts puts every number you care about on one screen.
Everything in one place
Apple Health metrics, CSV and TSV files, and live REST APIs — side by side on one dashboard. Overlay any two series and see how they move together.
Actually private
No servers, no accounts, no analytics — there isn't even a sign-up screen. Your data stays on your device, full stop. This page has no trackers either.
Feels native
Pure Swift and Swift Charts, built for iOS 26 and macOS 26. Interactive scrubbing, widgets, haptics, dark mode — it feels like Apple made it.
Everything you'd expect.
A few things you wouldn't.
Built by one person who wanted this app to exist — and kept going.
Deep Apple Health support
Heart, activity, sleep stages, breathing, body measurements — hundreds of metrics, charted the way Health should have.
Import any file
Drop in a CSV or TSV — supplements, workouts, finances, anything with a date column becomes a chart.
Live API sources
Point Charts at a REST endpoint and it keeps itself up to date — bank balances, home sensors, whatever you run.
Home Screen widgets
Any metric, any range, as a glanceable widget — small, medium, or large.
Insights that earn their place
Quiet, curated correlations — how sleep tracks with heart rate, caffeine with rest. No AI coach, no noise.
On the Mac too
The same app, native on macOS — your whole dashboard on a big screen.
