A task reminder app helps people remember what they need to do by sending timely alerts, so important items don’t get buried under everyday noise. It’s a small, practical project that teaches scheduling and notifications — skills you’ll reuse everywhere.
What it does
- Create tasks with a due date and time
- Send reminders before each task is due
- Mark tasks complete and track what’s outstanding
The core concept: scheduled notifications
The interesting challenge is firing a reminder at the right moment. A background job (a cron task) periodically checks for tasks whose reminder time has arrived and sends the alert — by email or push. Understanding that “check on a schedule, then notify” pattern is the heart of the project.
Technology stack
PHP and MySQL with a scheduled cron job to dispatch reminders. Add email or push delivery for the alerts.
What you’ll learn
Working with dates and times, running scheduled background jobs, and sending notifications reliably without sending duplicates.
Frequently asked questions
How are reminders actually sent on time?
A cron job runs at a fixed interval, finds tasks due for a reminder, sends them, and marks them sent so they are not repeated.
Email or push?
Start with email — it is simplest. Push notifications are a natural next step once the scheduling works.
A note on using this project
Use this PHP/MySQL project as a learning reference: read the code, run it locally, and adapt it to your own requirements rather than deploying it unchanged. If you reuse third-party components, check their licences first.
