You already capture reminders the easy way — a quick "Hey Siri," a tap on your Watch, a line typed into Apple's Reminders. The problem isn't capturing them. It's the wall of notifications that follows. Remindfully sits quietly on top of Apple Reminders and changes one thing: how they reach you. Instead of a buzz for every item, you get one calm digest each morning — everything due today, in a single glance. The things that genuinely can't wait still interrupt, at the moment they matter. Everything else simply waits in the digest, where it belongs. Your reminders never move. Remindfully reads from Apple Reminders and writes your changes straight back, so Siri, your Watch, and the Reminders app all keep working exactly as before. Nothing to migrate. Nothing to rebuild. WHAT MAKES IT DIFFERENT - One daily digest — a single summary notification each morning instead of a steady drip all day. - The important stuff still gets through — reminders set for a specific time can interrupt at that time, and anything you mark High Priority always breaks through, even when everything else is staying quiet. - Smarter about missed reminders than you'd expect — miss a daily reminder and Remindfully quietly rolls it to today. But miss a weekly or monthly one, and it stays clearly flagged, so a missed bill never disappears for three weeks. - Fix things without switching apps — create a reminder, correct a mistyped title or a wrong date, set or change a repeat, or delete something, all from inside Remindfully. Everything syncs straight to Apple Reminders. - A calm lock-screen card — see today's progress and what's next at a glance, check things off right from the lock screen, and glance at it on your Apple Watch. (Pro) - Per-list rules — let one list always interrupt while the rest stay in the digest. (Pro) FREE FOREVER - The daily digest, time-based interrupts, high-priority interrupts, completion sync, editing, and the full reminder mirror are free — no time limit. REMINDFULLY PRO — $4.99, ONE TIME - Unlock the lock-screen card and per-list interrupt rules with a single purchase. No subscription. Buy it once, keep it. - Remindfully requires access to Apple Reminders to read your items and mark them complete. It does not collect or transmit your reminders anywhere — everything stays on your device and in your own iCloud.
