Aktenzeichen XY... Ungelöst has run since 1967 on ZDF and remains a flagship show; the Inga Gehricke case triggered fresh waves of coverage from RTL, ZDFheute, n-tv, Tagesspiegel and MSN in 2024-2026, confirming large engaged German-speaking audience around specific cases.Vermisste Inga: Nach elf Jahren neue Hinweise durch Aktenzeichen XY (RTL) ↗Aktenzeichen XY: Rätsel um vermisste Inga Gehricke in Stendal (ZDFheute) ↗Aktenzeichen XY...

The official ZDF streaming portal already added 'Aktenzeichen XY... Update' (launched Aug 2025) plus 'XY gelöst' and 'XY history' verticals covering case progress and tips — direct free public-broadcaster competition — and a mature ecosystem of 916 German true-crime podcasts plus English-language case-database sites (CrimeTimelines, Uncovered, Cold Case Archive) already serves this niche.Neu: 'Aktenzeichen XY… Update' im ZDF-Streaming-Portal (ZDF Presseportal) ↗True Crime-Podcasts auf Deutsch: Marktstatistiken und Top-Sendungen (grep.fm) ↗Uncovered: Cold Case Files for Murdered or Missing People ↗
German true-crime consumption is dominated by free public-broadcaster content (ZDF/ARD XY ecosystem) and ad-supported podcasts; willingness to pay for a fan-companion around a free show is weak and no comparable paid German true-crime companion app surfaced.Neu: 'Aktenzeichen XY… Update' im ZDF-Streaming-Portal (ZDF Presseportal) ↗True Crime-Podcasts auf Deutsch: Marktstatistiken (grep.fm) ↗
Aktenzeichen XY has been on air continuously since 1967 and true-crime is a structural, multi-decade genre in Germany; the Inga case shows audiences still follow a single disappearance a decade later, signalling durable interest.Aktenzeichen XY...

Technically buildable as a content/notification app, but hard parts are jurisdiction-specific: each Bundesland has its own Polizei tip portal, GDPR/DSGVO applies to tip submissions, and German law around ongoing Ermittlungsverfahren and Strafvereitelung creates real legal/compliance risk for curating active cases or routing tips.Aktenzeichen XY...
