PillCurve is an interactive web application that calculates the remaining effects of substances based on dosage and pharmacokinetics. Customize your dosing schedule, visualize effect curves, and share your regimen with ease.

"In my humble opinion, the tool I have developed fills a significant gap in the digital landscape, addressing a need that, based on my extensive research, has not been met by existing solutions on the internet. My hope is that it will save many of us a lot of head-scratching and calculations. However, I would like to emphasize that what you see today is merely the first prototype. This current iteration represents the minimal viable product—the very first buildable draft that transforms an idea into a functional web application. It's a starting point, a foundation upon which much more can be built and improved. Your understanding and feedback at this early stage are greatly appreciated as we embark on this exciting journey of development and refinement."

• Preset Selection: Choose from a predefined list of substances or create custom presets.
• Custom Dosing: Personalize your dosing schedule with flexible timing and amounts.
• Starting Time Input: Specify your regimen's starting time with a user-friendly time picker.
• Interactive Chart: Visualize effect curves with markers indicating intake times.
• URL Sharing: Share your dosing regimen effortlessly via encoded URLs.

First, clone the repository and install the dependencies:

git clone https://github.com/aliciusschroeder/pillcurve.git
cd pillcurve
pnpm install

Note: This project uses pnpm as the package manager. If you don't have it installed, get it from here.

To run the development server:

pnpm run dev

Open http://localhost:3000 in your browser to see the app.

1. Select a Preset: Choose a substance from the preset list or create a custom one by entering the half-life and t_max values.
2. Enter Dosage and Timing:
   • Specify the starting time using the time picker.
   • Enter the dosage amounts.
   • For additional doses, specify the time after the starting time in minutes.
3. Adjust Doses: Add more doses by clicking the ➕ button or remove them with the ➖ button.
4. Calculate: Click on "Berechnen" to calculate and display the substance's effect curve.
5. Share: Use the URL to share your dosing regimen with others.
