Marrow Calendar

A calendar with no noise. Marrow Calendar is for people who want to see their time clearly. No crowded grids, no shouting colours: careful typography, room to breathe, one idea per screen. Your year, at a glance. Your day, with history. THREE VIEWS, ONE INSIDE ANOTHER · Year — all twelve months on a single page. Tap one to step in. Each year carries its own title and scrolls away with the calendar, like turning a page. · Month — continuous scroll, month after month. Days with plans take the colour of their event. · Day — your agenda, scrolling forwards and backwards with no arrows: the time, the place and a stripe of colour for every event. No tab bar. Swipe from the edge to go back and everything stays exactly where you left it. "Today" always brings you home. A PIECE OF HISTORY, EVERY DAY Every date has its own historical fact: one for every day of the year, February 29 included. Written calmly, with its year and category, and a link to Wikipedia for when you want to keep reading. The first time you open the app each day, the fact greets you. Prefer a nudge? Turn on a quiet notification at the time you choose. ELEVEN LOOKS Black and White are free. Marrow Plus adds nine more, from midnight blue to cocoa and rose, from ivory and graphite to deep space: Cobalt, Juniper, Linotype, Merlot, Ivory, Cocoa and rose, Toasted, Nebula and Eclipse. Each has its own base and its own ink, tuned to read well by day and by night. Switch with one tap, and your widgets follow. YOUR EVENTS, ON THE CALENDAR YOU ALREADY USE Marrow works on your iPhone's own calendar: what you add shows up in your other apps and travels through your iCloud. · Create and edit with repeats (daily, weekly, every two weeks, monthly or yearly), alerts, place search through Apple Maps, notes and a link. · Alerts that arrive: Marrow schedules its own, with your permission, even when Calendar's are switched off. · A colour for every event, so you can tell work from the weekend at a glance. · A live countdown on the page of every event that hasn't happened yet. · Search by title, place or notes, ignoring accents and capitals. WIDGETS · Fact of the day — small, medium or large, and on the Lock Screen. · Agenda — today's events in three sizes and on the Lock Screen. With Plus, the medium and large ones look past today and show the days ahead. · Countdown — the days, hours, minutes and seconds until the event you pick, in small or medium and on the Lock Screen. Plus only. NINE LANGUAGES Español, English, Euskara, Français, Deutsch, Italiano, Nederlands and Português (Brazil and Portugal). The app, the widgets, the alerts and each day's fact, in the language you choose; by default, your iPhone's. FREE, AND PLUS The app is free and complete: year, month and day; the fact of the day and its nudge; events with repeats, alerts, places and search; two looks and four event colours; the fact and today's-agenda widgets; and all nine languages. Marrow Plus is a single payment, forever, with no subscription. It adds nine looks, eleven more event colours, the countdown on your Home and Lock Screens, the agenda widget that shows the days ahead, attachments on events (the ticket, the receipt, the booking PDF, kept on your iPhone) and widgets without the signature. It restores on all your devices with your Apple ID. NO FINE PRINT No accounts. No ads. No analytics, no trackers. Your events live in your iPhone's calendar and your iCloud; we have no server and no copy of anything. Marrow Calendar. Your year, at a glance. Your day, with history.

Verdict
The clearest difference is update cadence: Marrow Calendar at every 2 days against Timemator's every 2 months. Timemator's advantage is device support (3 vs 1) and iOS requirement (16.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.
