Inverza: Photo Weather

Inverza is a weather intelligence app built for landscape photographers. It blends real-time forecasts from multiple models, live ground truth from airport METAR stations, GPU-accelerated terrain shadow mapping, an augmented-reality sky view, and AI analysis, so you're at the right place at the right time.

ASK AI ABOUT YOUR SHOT Type a question like "Will there be fog at Geroldsee tomorrow morning?" and get an informed answer grounded in live weather data. Inverza detects 16 photographic conditions: colorful dawn, golden clouds, ground fog (with marine and steam-fog paths), hoarfrost, dramatic storm clouds with phase-aware approach and departure windows, Milky Way, aurora, Belt of Venus, reflecting waters, soft light, full moon silhouette, Brocken spectre, lenticular clouds over mountain ridges, and more. Each comes with a confidence score and timing. The built-in AI works out of the box, no key needed. Bring your own Claude, Gemini, or ChatGPT key for more powerful models.

BUILT-IN PHOTOGRAPHER KNOWLEDGE The AI doesn't just read weather, it thinks like a landscape photographer. It knows the techniques and timing pros rely on: time blending across the day-to-twilight transition, storm chasing with phase-aware approach and departure windows, how dawn and afterglow timing shifts with latitude, altitude, and nearness to the sea, and how to read light direction relative to your subject. You get technique-aware guidance, not a generic forecast.

SEE THE SKY THROUGH YOUR CAMERA Point your phone at the sky and the AR View overlays the sun and moon paths, the Milky Way's galactic core, and twilight markers onto the live camera, tracked with ARKit. Scrub through time to watch the sun's arc cross your frame, find where the moon will rise, or line up the galactic core months ahead. Switch between your phone's lenses by focal length, from ultra-wide to telephoto, to plan the exact composition. Includes a compass cage with cardinal directions, guides to off-screen targets, tap-to-align calibration, and a dark-adaptation night mode.

NEVER MISS CONDITIONS AGAIN Set background alerts at your favorite locations and get notified hours before conditions align. Smart proximity filtering focuses on locations within driving distance. Multi-location alerts let one alert watch several spots at once, with reordering for priority.

DISCOVER & PLAN PHOTO SPOTS Browse an interactive map filled with photography points of interest from OpenStreetMap: viewpoints, waterfalls, castles, bridges, lighthouses, and more. Save curated spots, set viewing directions, and pair each spot with a photo subject pin (a mountain face, lighthouse, lake, or castle) so the AI reasons about lighting your subject, not just where the sun is. A 360° Horizon Paths view shows sun and moon arcs against the terrain and the real building skyline from OpenStreetMap, so you see what blocks your view.

SEE WHERE SHADOWS FALL A GPU-accelerated terrain shadow overlay (NASA SRTM elevation, Metal compute) shows exactly where sunlight reaches up to 30 hours ahead. Scrub the time slider or jump straight to sunrise or sunset. The map also supports 3D terrain, Look Around previews, and live sun and moon direction lines.

DARK-SKY AWARENESS Milky Way and Aurora detections factor in local light pollution via a bundled global Bortle raster (~1 km resolution). Inner-city skies hard-gate; suburban skies caveat realistically.
