Why we made it
After missing course updates more than once, we decided to make a reminder tool ourselves. A Web App helped us bring the idea to life sooner and make it accessible to more people.

Q&A
A few things before you begin
Do I need a native app?
No. This is a Web App, opened in a supported browser and added to the Home Screen. Your device must support the relevant Web Push features.
What is a connection code?
It pairs your device with the reminder service and comes from the administrator. It does not replace Rain Classroom sign-in and is not your account password.
Does it complete classroom tasks for me?
It does not answer exercises or respond to roll calls. Ordinary attendance may be entered with authorization; QR, location, and other restricted check-ins require normal completion in the official client.
Are notifications guaranteed to arrive on time?
Delivery depends on official event sources, browser subscriptions, the system, and the network. A push check helps confirm the device channel, not delivery of every real event.
What if a connection or login expires?
Device connections last 30 days and can be renewed manually. Monitoring stops when the official login expires; sign in again. You can also review and revoke unfamiliar devices.
Does the old address still work?
The old entry remains compatible. Use its safe migration flow to move to the new address, then add the new origin to your Home Screen and allow notifications again.
