Use Web Push reminders

Free keeps one-off reminders in the app and by opted-in email. Plus can deliver the same reminder through best-effort Web Push on up to five registered browser devices.

Open notification settings and choose Add this device. Daylume asks for browser permission only after that action. Give the device a calm label you will recognize, send a test if needed, and remove the device when you no longer want delivery there.

On iPhone and iPad, Web Push requires iOS or iPadOS 16.4 or later. Install Daylume on the Home Screen, open that installed app, then add the device and grant permission. A normal Safari tab cannot complete that flow.

Push is useful for ordinary task prompts, but delivery can vary with the browser, operating system, network, and power state. It should not be used for emergency, medical, or safety-critical timing. Daylume describes reminders as arriving around the chosen time, not at an exact guaranteed second.

Each registered device can be revoked separately. Removing a device stops future delivery to that browser; expired endpoints are removed from active delivery rather than retried indefinitely.

Keep Push selective. If an in-app or email prompt already reaches you at the right moment, another channel may add noise rather than value.
