Daymark is a private calendar for the small things you want to remember: a night's sleep, a mood, a weight, a symptom, a therapy session, a dose, a note. Record it in a tap, see it on the day it happened, and keep it to yourself. No account, no ads, no tracking. Some things don't belong in your work calendar or your notes app, but you still want to know when they happened. When did the headaches start? How many nights did you sleep well this month? When was your last appointment? Daymark keeps those answers on your iPhone, in one quiet place. RECORD ANYTHING, YOUR WAY • Start with Sleep, Weight, Mood and Note, or make your own types for anything else • Give each type a name, a color and a symbol • Markers save in one tap; numbers take a value and unit; text takes a word or a note • Spans cover things that last: a cold, a trip, a course of medication. Leave one running and end it when it's over • Record as many things on a day as you like, and add a note to any entry • Record for today, any past day, or a day still to come IDEAS FOR WHAT TO RECORD • Hours of sleep, and how you felt when you woke up • Mood in a word, or a sentence about the day • Weight, resting heart rate, or any number you measure • Headaches, migraines, allergies, flare-ups and other symptoms • Medication taken, or a dose that changed • Therapy sessions, doctor's appointments and check-ups • Periods and cycle days • Runs, swims, walks and workouts • Alcohol-free days, caffeine, or anything you're cutting back on • Calls with family, time with friends, trips and days off SEE YOUR DAYS AT A GLANCE • A monthly calendar marks every day with a dot for each kind of thing you recorded, in its own color • Open the year to see twelve months at once and jump to any day • History lists everything you've recorded, newest first, with search • Tap a type to see its chart over a month, three months, a year or all time • Markers show the days they happened, so the gaps are as easy to see as the busy weeks PRIVATE BY DESIGN • No account and no sign-up. We never see what you record • No ads, no analytics, no tracking and no third-party code • Works fully offline • Lock Daymark with Face ID, Touch ID or your passcode, and choose how soon it locks again • The app hides itself in the app switcher • Reminders say only that it's time to record, never what for, unless you choose otherwise • Optional iCloud Sync goes to your own iCloud account, never to us. It's off until you turn it on • Daymark does not read or write your Health data WHAT DAYMARK ISN'T Daymark doesn't score you, set goals, send streak warnings or tell you what your data means. There's no AI and no "insights". Charts show the values you entered, joined by straight lines, and nothing else. It's a record, not a coach. MADE FOR EVERY DAY • Reminders for any type, on the days and at the time you choose • Record an entry with Siri or the Shortcuts app • Recently Deleted keeps anything you delete for 30 days • Light and dark mode • iPhone and iPad • In English, Korean, Japanese, Chinese (Simplified and Traditional), Spanish, Portuguese, French, Italian, German and Dutch QUESTIONS Do I need an account? No. Open the app and start recording. Does it work without internet? Yes, everything works offline. Can I use it on my iPhone and iPad? Yes. Turn on iCloud Sync on both, signed in to the same Apple Account. What if I delete something by mistake? It stays in Recently Deleted for 30 days. BUY ONCE, NO SUBSCRIPTION No subscription, no in-app purchases and no free tier. Every feature is yours from the first launch. Daymark is a record-keeping tool, not a medical device, and it doesn't give medical advice.
