Plan your day your way with Reminder Planner. Reminder Planner is a simple and flexible way to organize appointments and reminders without unnecessary complexity. Create what you need, choose the schedule that fits your routine, and keep track of your day through the calendar and Home Screen widgets. Schedule an appointment or reminder using a single date, a date range, multiple selected dates, or specific weekdays within a period you choose. You can also quickly repeat items every day, choose a time, add optional notes, and enable notifications. Each occurrence can be marked as completed independently without affecting future repeats. Calendar See appointments and reminders together in one place. Select any date to view everything scheduled for that day and keep your plans easy to follow. Home Screen Widgets Reminder Planner includes interactive Home Screen widgets in multiple styles and sizes, giving you quick access to your day without opening the app. View today’s appointments and reminders, mark items as completed directly from the widget, and track remaining items and daily progress in supported widget designs. The widgets use an update system designed to move to the new day after midnight and refresh when your data changes. When the scheduled time for an appointment or reminder has passed, it is no longer included in remaining-item counts or progress calculations in widget designs that use this information. The amount of information and text displayed may vary depending on widget size, device, and available screen space. Notifications Reminder Planner supports local notifications for appointments and reminders. On iPhone, the app keeps up to 50 upcoming notifications scheduled at the same time and refreshes upcoming notifications when the app is used, within a planning range of up to 366 days. The app uses a bell sound only for notifications in the current version. Languages & Data Reminder Planner supports both English and Arabic. In the current version, planning data, appointments, and reminders are stored locally on your device. The appointment and reminder screens use a consistent design for dates, times, notifications, and repeat options, helping keep scheduling simple and familiar throughout the app. Subscription Full access requires an auto-renewable annual subscription. Your local price is shown in the App Store before purchase. Purchases, renewals, cancellations, and purchase restoration are managed through the App Store.
