About RxCal
RxCal is a free, open-source medication scheduling tool that generates printable dose schedules and calendar exports — with zero data collection. There's no account, no backend, and no tracking of any kind.
It was built for anyone who needs to track short-term medication — whether for a child with a fever, an adult recovering from surgery, an elderly parent on a multi-drug protocol, or even a pet on a vet-prescribed course.

- Temperature checkpoint rows with write-in fields
- Calendar export (.ics) for Apple, Google, Outlook, and Samsung Calendar

Built by
RxCal is a side project by HearneTech, a managed services practice based in East Texas. It started as a practical tool for managing pediatric fever rotations and grew from there.
Open Source
RxCal is open source under the MIT license. The entire application is a single HTML file — no build step, no dependencies, no npm. You can audit it, fork it, self-host it, or contribute on GitHub.
Disclaimer
RxCal is a scheduling tool, not medical advice. Always follow the dosing instructions provided by your doctor or pharmacist. When in doubt, call your healthcare provider.
