Keep reminding you until it's done!! The reminder went off, but you still haven't done it? 不忘提醒 (Never Forget Reminder) sends follow-up notifications for unfinished one-time tasks, helping you remember expense reimbursements, appointment preparations, and little things you need to take care of. It also supports daily, weekly, monthly, and yearly recurring reminders, lunar-calendar birthdays, and reusable countdown timers. 【One-Time Tasks: Remind You on Time, Then Again If Unfinished】 Enter a task and its time, and enable persistent reminders when needed. After the task is due, additional notifications will be sent if it hasn't been marked as complete. Once you've taken care of it, mark it as complete in the app to stop further app reminders for that task. Simply opening a notification does not mark the task as complete. You can also set reminders in advance for tasks that require preparation. 【Recurring Reminders: Set Once, Get Reminded on Schedule】 Set recurring reminders for daily tasks, selected days of the week, monthly bill payments, and more. Recurrence options include daily, selected weekdays, monthly, and yearly. Recurring reminders trigger on their scheduled dates, while persistent reminders are for one-time tasks that remain unfinished after their due time. 【Birthdays & Anniversaries: Gregorian and Lunar Calendars】 Keep track of family members' lunar-calendar birthdays and important anniversaries. Get yearly reminders and see how many days remain until the next occurrence. 【Countdown Timers: Set Once, Reuse Anytime】 Set countdown timers for cooking, brewing coffee, or short focus sessions. Pause, resume, and reset them whenever needed. On supported systems and devices, you can also check the remaining time through Live Activities on the Lock Screen and Dynamic Island. 【Important Tasks: Choose a Sound or Enable Alarm Mode】 Choose an alert sound from the built-in notification tones. Alarm mode is available for one-time reminders and countdown timers. 【Type a Time Instead of Tapping Through Dates】 Enter phrases like “Meeting tomorrow at 3 PM,” and the app will recognize common dates and times. Review the recognized result, tap Apply, and then save your reminder. Time recognition is performed locally on your device. 【Timeline, Calendar & Home Screen Widgets】 View your schedule in a timeline or calendar, and use home screen widgets to check upcoming one-time reminders and anniversary countdowns. With your permission, reminders can also be added to your system calendar for convenient schedule management. 【Local Storage & Manual Backups】 Basic reminders work offline without requiring an app account. Your reminder data is stored locally on your device. You can manually export backup files, import them to restore your data, or transfer them to another device.

Swipe right if it resonated, left to see it again sooner, or up to remove it. That's it. No clutter, no feeds, no noise, just the wisdom you already collected, working its way into how you think. Features: - Daily highlight cards with swipe gestures - Spaced repetition intervals that adapt to your reviews - Quote Mix to control which books appear more or less - Customizable daily highlight count (3 to 15) - Share beautifully designed quote cards - Streak tracking with a global leaderboard - iCloud sync across all your devices - Light and dark mode - Completely free, no ads Cogi is built for readers who believe the best ideas deserve more than one reading.
