Most weather apps tell you it rained. Mollzometer tells you if it rained on you. Set your hours. Get your forecast. Mollzometer filters the entire day's weather down to the hours you're actually outside — your commute, your workday, your run. No more checking the forecast and realizing the "morning rain" was at 5am while you were asleep. Your Hours, Your Forecast Tell Mollzometer when you wake up, when you commute, and when you're home. It does the rest — surfacing only the weather that actually affects your day. Know What to Wear, Every Morning Mollzometer suggests exactly what to wear based on the coldest, wettest moment inside your active hours. Not the whole day — just your day. And if the morning and evening feel completely different, it'll tell you that too. Your Wardrobe, Your Rules You decide what 55°F means to you. Set your own temperature thresholds for every layer — t-shirt, sweater, coat, heavy coat — and Mollzometer will match its suggestions to how you actually dress. Smart Alerts That Mean Something Get a single morning briefing built around your hours. No noise, no spam — just "Sweater plus raincoat today, rain likely at 3pm" delivered before you walk out the door.
