How it works

  1. Use your Sunbloc account. The app is part of this website, so you log in with the same email and password as your account here (the same free account as the course). No separate sign-up and no Google account needed.
  2. Open the app. Go to /app. The first time, you'll accept the beta user agreement.
  3. Start free. Create a project, enter your site, loads and components, then build your designs.
  4. Unlock reports. Buy 3 report credits for $29. Reports and the weather lookup open straight away and stay unlocked for good.
  5. Make reports. Each report uses one credit. Out of credits? Your designs stay open; buy 3 more whenever you need another report.

Your report credits are on your account page.
