I built a family calendar with Lovable and Claude that integrates with our Google Calendars and Todoist projects. My husband, son, dog, and I were struggling to track our schedules in one place. Although we had shared our calendars through Google, we did not have a central view displayed in the house, and the interface became cluttered when we tracked multiple calendars. We had considered buying a Skylight calendar for years, but it costs $300, and we were not convinced we needed all of its extra features. I decided to build my own instead. Step-by-step: 1. I created a product requirements document (PRD) for a family calendar in Claude. It prompted me to choose the available views, decide how to organize each family member’s calendars, support both events and tasks, and add extras such as the day’s weather and a photo background. 2. I shared the PRD with Lovable, which built the first version of the calendar. Lovable helped me integrate my Google Calendars and Todoist projects so that all of our events and tasks appeared in one place. It also helped me integrate Google Photos so our family photos could rotate in the background. 3. I launched the calendar as a password-protected website so any family member could access it from anywhere. 4. I placed the calendar on an iPad in our kitchen and edited it as we used it, learning which features were most and least helpful. I also added calendars for my in-laws when they visited for several months at a time. Claude continues to help me draft new requirements, which I share with Lovable. The calendar is tailored to our needs and costs much less than the Skylight option. The photo feature also makes it feel personal, and I look forward to continuing to evolve it over time.
