How do I send myself a reminder from a script?

A reminder is just a notification you schedule. Any shell script, cron job, or scheduled task that can run curl can nudge your phone at the right moment — no reminders app, no calendar integration, no login. Because your Lert link is the credential, the whole reminder is one command you can paste into crontab.

The entire setup — under 30 seconds

1. Download the app. Open it once. There's no account to create, and your private link is waiting on screen.
2. Copy your link. One tap copies something like https://lert.dev/p/your-id.
3. Curl it, then schedule. Send a one-off reminder now, or add it to cron to repeat on any schedule.

Then your phone buzzes — instantly, even locked in your pocket.

The command

# send one reminder right now
curl -X POST "https://lert.dev/p/your-id" \
  -H "Content-Type: application/json" \
  -d '{"title":"Stand up","body":"Stretch and refill water","tag":"reminder"}'

# or repeat it — crontab entry, every weekday at 9am
0 9 * * 1-5 curl -s -X POST "https://lert.dev/p/your-id" \
  -H "Content-Type: application/json" \
  -d '{"title":"Daily standup","body":"Post your update"}'

Change the cron expression to control the timing — 0 9 * * 1-5 is 9am on weekdays. Prefer a one-off later today? Pipe the same curl through at. Plain text works too if you skip the JSON and just send a string as the body.
