Sonntagsplaner NRW
A family weekend planner for North Rhine-Westphalia that combines verkaufsoffene Sonntage, city festivals, Kirmes dates, and weather into one decision-friendly view so parents don't have to piece it together from eight regional news sites.
Parents in NRW planning a Sunday family outing and tired of checking the Ruhr Nachrichten, KSTA, and local city sites separately
- City-by-city calendar of verkaufsoffene Sonntage with participating shops and exact opening hours (13-18 Uhr in most NRW cases)
- Family-scored filters: 'kid-friendly festival today', 'indoor option if rain', 'free entry', 'within 30 min drive'
- One-tap itinerary builder that combines a shop, a Kirmes, and a lunch stop into a shared family link
- Push reminders on Friday afternoon with the best three Sunday options for the user's home city
Every weekend NRW families face the same fragmented search across at least five regional news outlets, and the data (cities, dates, hours) is public but never aggregated — a perfect narrow niche.
Clear recurring demand: multiple long-running SEO-optimized sites already monetize verkaufsoffene Sonntage in NRW (verkaufsoffener-sonntag.com, sonntagsoffen.de, verkaufsoffener-sonntag.nrw) and 24rhein/wa.de publish yearly Kirmes PDFs, proving parents actively search this info weekly — but the brand term 'Sonntagsplaner' returned zero results, so the combined aggregator intent is unproven.Verkaufsoffene Sonntage in Nordrhein-Westfalen 2026 (Liste) ↗Kirmes in NRW: Termine für 2025 im Überblick zum Herunterladen ↗
Whitespace narrower than initially scored — three dedicated verkaufsoffene-Sonntag aggregators and fotho.de's Kirmes calendar already serve parts of this need; only the combined family-decision UX (Sonntage + festivals + Kirmes + weather in one feed) appears genuinely uncovered, and even that is a thin productization layer on top of free content.Kirmeskalender NRW - Alle Volksfeste auf einen Blick - fotho.de ↗Verkaufsoffener Sonntag in Nordrhein-Westfalen (NRW) ↗
Weak monetization case: existing competitors give the same data away free with ads, the use case is 2-3 weekend peaks per month, family audiences are notoriously ad-blocked in DE, and 'Sonntagsplaner' has no incumbent subscription benchmark — local retail/event sponsorship or affiliate to Kirmes operators is plausible but unvalidated.Germany App Monetization Software Market Emerging Digital ↗Kirmes-Spaß in NRW: Die Termine für 2025 im großen Überblick - wa.de ↗
Good longevity — Sonntagsöffnungs data is calendar-bound and legally regulated, Kirmes/Stadtfest dates are perennial, and parent weekend-planning pain is structural; the content ages on a 12-month cycle rather than going stale.ᐅ Verkaufsoffene Sonntage - alle Termine im Überblick ↗
Highly feasible MVP — all four data sources (Sonntage, festivals, Kirmes, weather) are publicly scrapable with public APIs (DWD for weather, city/press calendars), no ML required, shippable as a mobile web app in weeks rather than months.Kirmeskalender NRW - Alle Volksfeste auf einen Blick - fotho.de ↗
