Frequently Asked Questions
What is a Custom Reminder Pad?
A Custom Reminder Pad is a free online tool that combines sticky-note simplicity with alarm-clock functionality. Set time-based reminders with personal notes directly in your browser β no downloads, no sign-ups. Perfect for medication alerts, meeting nudges, task deadlines, and daily routines.
Do I need to install anything?
No installation required. This reminder pad runs entirely in your web browser using HTML5, localStorage, and the Web Notification API. Just bookmark the page and you're ready to go. It works offline once loaded and stores all your reminders locally on your device.
How do recurring reminders work?
You can set reminders to repeat daily, weekly, or monthly. When a recurring reminder triggers, it automatically reschedules itself for the next interval. For example, a daily reminder set for 8:00 AM will fire every morning at 8:00 AM until you manually complete or delete it.
Will reminders work if my browser is closed?
Reminders only trigger while the tool page is open in your browser tab. This is a browser-based tool (not a native app), so it cannot wake your device from sleep. For critical reminders, keep the tab open in the background. We recommend enabling browser notifications for the best experience.
How do I enable sound and notifications?
Click the "Sound" toggle to enable audible alerts. When a reminder fires, the tool plays a chime using the Web Audio API. For system notifications, allow the browser permission prompt when it appears. You can manage notification permissions in your browser settings at any time.
Is my data safe and private?
Absolutely. All your reminder data is stored locally using your browser's localStorage. No data is ever sent to any server. Your notes, titles, and schedules remain private on your device. Clearing your browser data will remove saved reminders, so consider backing up important ones.
Can I use this on mobile devices?
Yes! The Reminder Pad is fully responsive and works on smartphones and tablets. On iOS Safari and Android Chrome, the interface adapts seamlessly. For the best mobile experience, keep the browser tab open and your device unlocked to receive in-browser alerts.
What is the snooze feature?
When a reminder fires, you can snooze it for 5, 10, or 15 minutes instead of completing it immediately. The reminder will re-trigger after the snooze period. This is handy for non-urgent tasks or when you need just a few more minutes before acting on a reminder.
How do priority levels help?
Priority levels (High / Medium / Low) add visual cues to your reminders. High-priority items get a red accent, medium gets orange, and low gets blue. This helps you quickly scan your list and identify which reminders need immediate attention versus those that are less urgent.
What browsers support this tool?
The Reminder Pad is compatible with all modern browsers: Google Chrome 90+, Mozilla Firefox 88+, Safari 14+, and Microsoft Edge 90+. Web Notifications and Audio API are widely supported. For the notification feature, ensure your browser permissions are granted.
