PhotoWeather App's answer

Backend & data

• Python + FastAPI (API backend)
• PostgreSQL + SQLAlchemy (data storage + ORM)
• Celery + Redis (background jobs, scheduled fetching, evaluation, notifications)
• NumPy (vectorized high-performance rule evaluation)

Frontend

• React + TypeScript + Vite (web UI)
• React Native + Expo (iOS & Android)

Integrations

• Open-Meteo multi-model weather forecasts
• NOAA data including GFS / GEFS for advanced fields (Pro)
• Copernicus Atmospheric Monitoring Service aerosols (CAMS) for clarity/red-sky analysis (Pro)
• RFC 5545 iCal feeds (calendar integration)
• Stripe (billing + subscriptions)

PhotoWeather App's answer

Choose PhotoWeather if you want repeatable, customizable, low-noise “show up at the right time” decisions—not another app that makes you interpret weather charts yourself.

Compared to typical weather + photo planning apps, you get:

• Customization depth (rules + derived signals + astronomy + trend operators).

• Confidence + evidence: confidence scoring plus “why it matched” style evidence panels and semantic event titles (so alerts read like “Dense Fog at Sunrise” rather than “Rule #7”).

• Better data strategy: multi-model selection and (Pro) multi-model consensus + ensembles + aerosols + marine + upper-air dynamics for hard photo cases like dramatic skies, clarity/haze, aurora, or coastal conditions.

• Fewer notifications, more useful ones: session grouping + peak time + smart merging is designed explicitly to reduce noise.

• A clear upgrade path: Free is enough to prove value (1 location / 3 rules / 3-day horizon), while Pro unlocks the full forecasting + advanced data + operators.

PhotoWeather App's answer

Photographers who plan around light and atmosphere—and want the app to do the monitoring and interpretation.

Primary audience segments:

• Serious hobbyists & landscape photographers chasing fog, golden/blue hour, cloud drama, and “right place/right time” conditions. 

• Aurora hunters & night-sky shooters who need alerts that combine space-weather activity with local viewing conditions (darkness, cloud cover, visibility).

• Coastal / storm / dramatic-sky photographers who care about wave state, wind, instability, and structure—not just “rain yes/no.”

• Creators who need repeatability (content schedules, travel planning, workshops): calendar integration + session-based opportunities make it easier to commit to plans.

PhotoWeather App's answer

PhotoWeather exists because great photo conditions are fleeting—and most tools force photographers to babysit forecasts and translate raw weather data into “will this actually look good?”

So the product flips the workflow:

1.  you describe the look you want (foggy sunrise, cloud breaks at sunset, clear astro night, etc.),
2.  PhotoWeather evaluates future hours across your locations,
3.  it alerts you only when conditions line up—packaged as a shootable session with timing and confidence.

PhotoWeather App's answer

PhotoWeather is built around photography outcomes instead of generic weather stats. The core idea is: you define what “good conditions” mean (in your own terms), and PhotoWeather turns forecasts into shootable sessions with confidence and timing. 

What’s genuinely different:

• A rule engine for photographers (not “alerts for rain”): nested AND/OR/NOT logic, sunrise/sunset offsets, astronomy periods, and even trend-based operators (Pro) like rolling sums/means/slope to describe patterns over time.

• Photography-specific “derived conditions”: it computes things like fog probability, golden hour potential, aurora quality, red-sky potential, cloud drama, coastal drama, etc., from multiple underlying fields—so you don’t have to manually interpret 15 parameters.

• Period-based opportunities (low-noise by design): instead of spamming hourly pings, it groups consecutive matching hours into sessions, finds the peak moment, merges adjacent periods, and assigns a confidence score.

• Directional weather intelligence (Pro): it samples conditions ~100km around your locations to better predict phenomena like rainbows, golden light, and red skies—because what’s happening toward the sun often matters more than what’s overhead.

• Calendar-first execution: private iCal feeds that drop opportunities onto Apple/Google/Outlook so you can plan like a pro, not like a doom-scroller.
