The definition of bad weather is quite subjective. Each of us has a unique sense of weather perception. Some can’t stand the cold, others like the feel of frost on cheeks, some like reading while it rains and others get depressed because of rain. When you see 7℃, what does it say to you? You need to think a fraction of a second to realise is that good weather or bad one. Bad Weather app just tells you straight – it will be bad weather, according to your criteria, of course. But wait, is that enough? Is just knowing the good or bad weather is what we need? Partly. When it is good weather – no much additional info required, this fact itself is fulfilling. In case of bad weather coming – we need to know when, or how much time we have until it finally reaches. This app does exactly that – shows you a countdown to the next bad weather event, and again, according to your definition of bad weather.

When the forecast is wrong, locals fix it. Penji Weather AI shows official forecasts — and lets you fix them when reality doesn’t match. If the app says sunny but it’s raining, report it in one tap. Choose rain, snow, fog, wind, heat, flood, or danger (storm, hail, tornado, hurricane, flash flood, whiteout, smoke, ice, and more). Set intensity low, medium, or high. Nearby users see Community Signals so everyone gets a clearer picture of what’s actually happening outside. WHY PENJI IS DIFFERENT Most weather apps only show data from far-away sensors. Penji adds a local layer: real people near you reporting what they see right now. When the app and the sky disagree, you’re not stuck guessing — you can report it and see what others nearby are experiencing too. COMMUNITY MISMATCH REPORTS • One tap to report wrong weather • Choose the actual condition: rain, drizzle, snow, fog, wind, heat, flood, or danger • For dangerous weather, pick the type: storm, hail, tornado, hurricane, and more • Set how strong it feels: low, medium, or high • See Community Signals when nearby users report changing conditions • Helpful local context when official forecasts lag behind real life DAILY PENJI BRIEFING Every day, get a short AI summary for your city: • Outfit tips — what to wear before you walk out the door • Safety advice — heat, cold, rain, wind, storms, and visibility • A quick read on today’s conditions so you can plan your morning in seconds ASK PENJI AI Talk to your penguin weather assistant. Ask natural questions about rain timing, storms, air quality, heat or cold, and outdoor plans: • What should I wear today? • Do I need an umbrella or a jacket tonight? • Will it rain or storm today or tomorrow? • Is it good to run, hike, bike, or play sports outside? • How’s the UV — do I need sunscreen? • Is the air quality okay for outdoor activity? • Is it safe to drive or walk in these conditions? Penji gives clear, friendly answers focused on daily decisions — not just numbers on a screen. FULL WEATHER FOR YOUR CITIES • Search and save favorite cities and locations • Current temperature, feels-like, and conditions • Wind, humidity, rain, visibility, UV, pressure, and air quality • Sunrise, sunset, and moon phase • Detailed weather breakdowns when you want the full picture • Live radar with Penji Pro BUILT FOR REAL LIFE Whether you’re commuting, running, hiking, heading to the beach, or just deciding if the kids need a jacket, Penji helps you plan around the weather — with forecasts, local reports, and AI advice in one place.
