## What is Inverza?

Plan your next landscape photograph around the light. Inverza brings weather forecasts, photographic conditions, terrain shadows, sun and moon paths, AR planning and AI explanations into one app, made by a landscape photographer.

FIND PHOTOGRAPHIC CONDITIONS
Explore 16 conditions, including colourful dawn, afterglow, cloud inversions, ground fog, hoarfrost, fresh snow, lenticular clouds, Brocken spectres, reflecting waters, the Milky Way and aurora. Each prediction includes a suggested time and a confidence band to help you compare opportunities.

Dawn and afterglow analysis checks cloud layers up to 450 km towards the sun, estimating whether light can reach the clouds above your location. Detectors also consider available upper-air profiles, aerosols, nearby airport observations, water conditions and light pollution. Forecasts remain estimates, and local conditions can differ.

ASK ABOUT YOUR SHOT
"Will there be fog at the lake tomorrow morning?" Ask in plain language and get an explanation based on the weather and your selected location. Built-in Gemini 3.8 Flash (18+) needs no API key. You can also use your own Claude, Gemini or ChatGPT key. AI sharing requires your permission; maps, weather and planning work without AI chat.

PLAN SUN, MOON AND SHADOWS
Use the terrain shadow map and time slider to estimate where sunlight reaches. A 360° horizon chart places sun and moon paths against terrain and mapped buildings. Explore the scene in the 3D Diorama, including solar-eclipse planning through 2030. Terrain and building detail depend on the available source data.

SEE THE SKY IN AR
Overlay sun and moon paths, the Milky Way's galactic centre and twilight markers on your live camera view. Move through time, choose a focal length and prepare your composition. Compass calibration, guides to off-screen targets and night mode help you plan in the field.

SAVE SPOTS AND SET ALERTS
Discover viewpoints, waterfalls, castles, bridges and other photographic locations from OpenStreetMap. Save your favourites, set a viewing direction and mark your photographic subject. Create alerts for one or several spots and filter by proximity. Notifications depend on permissions, connectivity and iOS background scheduling.

REVIEW AND SHARE
Record whether a predicted condition happened and review your own judged predictions in Condition History. Long-press a condition badge to share a card. Inspect the underlying forecasts in Raw Weather Data, including cloud layers, aerosol optical depth, model agreement and winds aloft.

ONE SUBSCRIPTION, ALL FEATURES
A 14-day free trial includes full access, followed by an annual subscription. The local price and renewal terms are shown before purchase. Cancel renewal in your App Store subscription settings.

No account required. No in-app ads. Available in English, German, French, Spanish and Italian.

PRIVACY
Saved spots and chat history are stored on your device. Weather and map services receive the location information needed for their features. With your permission, the selected AI provider receives your question and relevant conversation, location and planning context.

Simple interface, solid forecasts, no bloat. The AI chat is useful for "is this condition realistic tonight?" type questions. Haven't missed a condition window since installing.

Refreshing to find an app that's honest about what it collects. No ads, no sketchy analytics, data stays on-device where possible. Combined with the low price and a generous 14-day trial, this feels like the rare iOS app built by someone who actually uses it.
