What it does

Subscribers pick a time for a daily reminder to take their product, saved to their calendar.

Why it exists

For any merchant whose product works best as a daily habit. One tap adds a recurring reminder to Google or Apple Calendar, with no app to install.

The code

Paste it as-is, or download daily-reminder.html

How to install

  1. Copy the code above, or download the .html file.
Your portal
  1. Go to Storefront → Customer Portal → Branding → Layout and click Add custom extension.
  2. Pick HTML with embedded CSS and JavaScript and paste the whole file into the code editor.
  3. Swap anything the file asks you to, like [BRAND], product names or Quick Action IDs. The AI prompt below can walk you through it.
  4. Save, click + to add it to the layout, then Publish. Check it on a test subscription’s magic link with ?forcePreview=true, since some scripts don’t run in Preview.
Before you paste

Replace [BRAND] in the copy and in the calendar event. It is designed to sit next to the Challenge Tracker on the same page.

Customize it with AI

Paste this prompt into Claude Code or Codex. It asks for the code and your brand and product details, then writes a version for your store.

Blocks are shared as-is by the people who built them. Read the code before you add it to your portal, and test it with a test subscriber first.
