The calendars show what's happening; they never show how it's going to feel. So I built Barometer in @Flowstep , an emotional weather report for your week. It reads the shape of your calendar and gives you an honest heads-up about the next week. ❓Why I built this: I like taking a moment to reflect on my day, sometimes looking back at it, sometimes looking ahead at what's coming. I always wished calendars did a bit of that too. Plus, it also helps you answer the question “Am I just lazy or was my day really exhausting?” ⚒️ How I built it: - Started in Claude: app brief, user flows, and a design system. - Connected Claude to Flowstep and prompted straight from that project context. - Built home, one example day in full, then generated the rest as variants of it to keep the system consistent. - Used Flowstep's design panel for the small, final tweaks. 📚 What I learned along the way: - Flowstep needs clear color, copy, and reference, but also room to make its own decisions. Over-specify and the layout gets confused; give it space and it makes a really good judgment. - Prompting multiple related screens in one pass kept the system tighter than one screen at a time. But even prompted individually, it remembered the guidelines across screens. - Sometimes plain chat, not a structured prompt, got the better result for a tweak. 🧐 One thing I kept thinking while building this: it doesn't need to be its own app. This could just as easily live as a "forecast" layer inside a calendar app you already use.
