Web System for Medication Deliveries

I need a simple and functional web system to manage the delivery of two medications for a clinic. The system should operate smoothly on both desktop and mobile devices and can be created using tools like Google Scripts + Excel, Airtable, Glide, AppSheet, Coda, or any similar platforms.

The core functionality required is to enable clinic staff to manually assign delivery dates and times for medications. Additionally, the system should support WhatsApp notifications for delivery reminders.

Please ensure the tool is user-friendly for our staff and designed for efficient scheduling and communication. If you have expertise in any of the suggested tools or similar solutions, I look forward to hearing from you!
