Your calendar manages your schedule. Annidiem remembers the days for you. If you think you're a bit ahead of the curve, this one's for you. Birthdays, anniversaries, exams, trips, moving into a new home, a family reunion — the days that matter deserve better than a crowded calendar. Some are still ahead of you. Some already happened. Either way, they deserve somewhere to stay. Flip the bottom-right corner of a card and it turns over into that day's own record. You don't have to wait for the day itself — write while you're looking forward to it, while you miss it, or the moment it crosses your mind: photos, thoughts, voice memos, short videos, each one stamped with the place and weather of that moment. No folders to create, no "where should this photo go" — it belongs to a day, so it stays with that day. If you remember which day it was, you'll find it again. And when the same day comes round again, every year keeps its own: this year never mixes with last. When a day is no longer in focus, put it away — not throw it out. It leaves your home screen and stops reminding you, while the diary and photos stay, ready to bring back. Life gets simpler. The memories don't have to. - TALK TO THIS DAY — flip a card over for that day's own record; write whenever it comes to you - ARCHIVE — put days that no longer need your attention away, without deleting anything - CARD WALL — big countdown numbers for every day that matters - TICKING MOMENTS — live days/hours/minutes/seconds; past days keep counting up: 1000 days together, 90 days smoke-free, day 300 of the project - WEEK & DAY OF YEAR — which week and day of the year today is, at a glance - PHOTO COVERS — pick a photo for a date and the card becomes its face - ON THIS DAY — the days that happened on today's date in past years surface on their own - DYNAMIC ISLAND — pin any day to your Dynamic Island - WIDGETS — gradient cards, Lock Screen widgets, and a large widget that shows your next five days - ERA OF DAYS — one 3D timeline for all your days: days with photos stand along the road, tap one to fly in - APPLE WATCH SYNC — a glance at your wrist: watch app and watch face complications, updated from your iPhone - TAKE A BREATHER — the screen dims, and the fireworks begin - WORTH SHARING — five share card styles: gradient, minimal, poster, midnight, photo - ANY RHYTHM — daily, weekly, monthly, or an interval you set yourself; paydays and bill days stay in step - FIND ANY DAY — search titles, notes, even "August"; filter to this month, the next 30 days, or what's already past - ASK SIRI — "how many days until New Year?" works, and so do Shortcuts and system search - REMINDERS YOUR WAY — the day itself, or 1/3/7/14/30 days ahead, at a time you choose - TYPE DAYS, GET DATES — enter "100 days" and the date computes itself - FACE ID LOCK — auto-lock in background; some days are yours alone - CALENDAR BRIDGE — import from system Calendar; export .ics/JSON to iCloud Drive - ICLOUD SYNC — sign in to iCloud and every device stays in sync - DATE CALCULATOR — days from birth to today, or today to payday; days between dates, business days, and more - ON-DEVICE AI BLESSINGS — Apple Intelligence writes personalized blessings, fully offline (iPhone 15 Pro or later) One-time purchase · No subscription · No ads · Collects no data — your data stays on your device and in your own private iCloud database, and everything works offline.
