One reminder is rarely enough.

A single notification can get lost in the noise of daily life. Deadlines shift, plans change, and important tasks slip through the cracks.

Most reminder apps stop after one alert. Real life is messier.

You need time to prepare, prompts before you leave, and nudges if something important gets buried. One alert is often not enough to move a task all the way to done.

That is the gap this app fills. ReminderOS sends pre-reminders and persistent follow-ups so important reminders stay visible until you finish them.

Pre-reminders

Add early nudges before the main reminder so you have time to prepare, pack, or switch context.

Persistent

follow-ups

If you miss the first alert, important reminders can keep resurfacing instead of disappearing after one swipe.

Flexible

schedules

Set daily, weekly, monthly, or more custom repeat patterns so your reminders match the routine you actually follow.

Private iCloud sync

Your reminders stay in sync across your Apple devices without turning your schedule into an ad product.

Subtasks

for bigger reminders.

Break bigger reminders into smaller steps, track what is done, and keep momentum without losing sight of the whole task.

Urgent reminders

When timing really matters, mark reminders as urgent so they stand out more than an ordinary notification.

Quick snooze

Nudge a reminder forward when you need a little more time, without rebuilding the task from scratch.

How people use ReminderOS

Work and deadlines

Pre-reminders help you prepare, and persistent follow-ups keep meetings, submissions, and follow-through from slipping.

See ReminderOS in action

Be ready on time

Set one reminder the night before a flight and another when it is time to leave, so important plans do not start at the last minute.

Get nudges until it is done

If you still have not sent the invoice after the first alert, the reminder can come back later in the day until it is done.

Plan your task in steps

Turn a bigger reminder into booking, packing and tickets, or any other steps you need, so you can see what is left without losing the bigger task.

Why ReminderOS feels different

The goal is not just to send a reminder. It is to help important tasks stay visible long enough for real life to catch up.

Frequently asked questions

What makes this different from a standard reminder app?

Most reminder apps stop at a single alert. This app is designed for reminders that need more support, with earlier preparation prompts and follow-ups that keep important tasks visible when the day shifts.

What are pre-reminders?

Pre-reminders are earlier nudges scheduled before the main reminder time. They give you space to prepare, leave on time, or get context back before the actual due moment arrives.

How do persistent follow-ups work?

Persistent follow-ups are additional reminders for tasks that still matter after their original due time. Instead of disappearing after one missed alert, important reminders can keep resurfacing until you act on them.

Can I use it for overdue tasks?

Yes. The product is built around the idea that some tasks should not vanish just because one notification was missed. Overdue reminders can stay in motion instead of fading into the background.

Who is it best for?

It is best for people who need more than a single ping, especially when timing matters, tasks are easy to miss, or a reminder needs to stay visible until it is actually handled.

Does it work for one-off reminders and repeating reminders?

The app is centered on important reminders that need better timing and follow-through, whether that is a one-off task or part of an ongoing schedule.

Keep the important things in motion.

Give yourself more than one chance to remember. Start earlier, stay on top of overdue tasks, and keep important reminders visible until they are actually handled.

Founder's note

I built ReminderOS because one reminder kept failing me.

The problem was never writing things down. It was that one alert was too easy to miss, especially on busy days when the important things needed more than one chance to come back into view.

ReminderOS is my attempt to make reminders feel more supportive and more honest about real life. Sometimes you need a heads-up before the task. Sometimes you need a follow-up after it. Sometimes you need a reminder to stay with you until it is actually done.
