The tracker that doesn't track you.
You're probably already tracking things: gas mileage in a ratty old notebook in your glovebox, a Note called "plant watering," your memory for the headaches. Plus a folder of single-purpose apps that each demanded an account.
Coffee. Mileage. Mood. Spending. Baby feedings. Practice hours. Pain levels. Sleep. Pull-ups. The sourdough starter.
TRACK ANYTHING
Create a tracker for anything in seconds. Pick its unit (miles, dollars, cups, °F, percent, or one you invent) and log with the capture style that fits: a stepper, a tally pad, a dial you spin. Yes/no habits, ratings, colors, and short notes work too.
CHECK IN, DON'T FILL OUT
Bundle trackers into check-ins (a morning check-in, a workout, a refuel) and log them all in one pass, with the note, photo, and weather attached to the moment.
START FROM THE LIBRARY
Browse ready-made check-ins (Rise & Shine, Refuel, Baby Log, Plant Care) and make them yours. Everything in the Library is free.
SEE WHAT IT ADDS UP TO
Trends, streaks, comparisons, distributions, heatmaps. Honest charts that never exaggerate your data, on a dashboard you arrange yourself. Scrub any chart with a finger. Every chart speaks VoiceOver. Share any view as an image.
MAKE IT YOURS
Dye the whole app your color: any tint, any backdrop, light or dark, not just an accent on a button. Charts, heatmaps, every screen wears your theme. Even our logo will, if you let it. Save your looks as presets. Your Datum won't look like anyone else's.
MORE THAN NUMBERS
Attach photos, voice notes, and text. Let a tracker capture location, weather, or your calendar automatically, only where you say so.
PLAYS WELL WITH OTHERS
Log by voice with Siri or wire Datum into your Shortcuts. Send a photo, a link, or text from any app straight into an entry with the share sheet. Import years of spreadsheet history from CSV. Share a check-in as a small file a friend can open in their own Datum, trackers included.
YOURS. ACTUALLY YOURS.
No account. No sign-up. No server of ours holding your life. Your data stays on your devices and in your private iCloud, syncing across your iPhone and iPad. We couldn't read it even if we wanted to. Export everything to CSV or JSON whenever you like. It's your data; leaving is easy, so we make staying worth it.
NO SUBSCRIPTIONS
Datum is free for up to 10 trackers and check-ins. Unlock unlimited forever with a single purchase. Nothing renews. Nothing is rented. Founding pricing is available through December 1, 2026. The price only goes up from here.
Track anything. Keep it yours.
Datum could crash while waking in the background to sync, if a place trigger asked for your location before one was cached. It now waits for the next launch that has one.
Datum also runs on iOS 26.0 now, down from 26.5, so an iPhone or iPad a version or two behind can install it.
Still fixed from the last update, if you skipped it: place triggers in Automations could crash Datum at launch, and importing a CSV that repeats a column name crashed the mapping screen. Neither does now.
