Your reminders

No saved reminders.

Saved only in this browser. This is a reminder list; it does not send notifications. If browser storage is blocked, changes last only for this session. Inspection, wear and product instructions can require earlier action.

Example

A toothbrush replaced on January 31 gets an April 30 reminder. A custom interval uses elapsed days instead of calendar months.

How to use this guide

Choose an item and enter when it was last replaced or cleaned. For toothbrushes and contact lens cases, the reminder uses 3 calendar months; toothbrush guidance gives 3–4 months and this tool uses the early end. Portable humidifier tank cleaning uses 3 days during use. Other products require an interval you supply from the manual or a personal reminder choice. No unsupported universal lifespan is assigned.

Frequently asked questions

Will I get a notification?

No. Open this page to see due dates. The list is stored only in this browser.

Why do many items require my own interval?

Wear, product design and manufacturer maintenance instructions differ. A single universal number would be misleading.

Can I override the default?

Yes. Enter a whole number of days from 1 to 3650. The list marks it as your interval.
