DuelCast
A multi-sport matchday companion that watches two simultaneous live events for you and pings you only when something happens in the one you're not actively watching.

- One-tap audio stream switching between two live radio commentaries
- Personalised 'priority list' so your favourite sport wins ties automatically
The Open's final round is colliding with the World Cup final at MetLife Stadium on the same Sunday — exactly the kind of once-a-year conflict fans routinely complain about on social media.
The 154th Open final round at Royal Birkdale and the 2026 FIFA World Cup final at MetLife Stadium are both confirmed for Sunday 19 July 2026, creating a genuine high-interest collision for British fans; 'ryan fox' trending 200+ in GB supports active golf interest.The 154th Open at Royal Birkdale | The Open ↗2026 FIFA World Cup final - Wikipedia ↗The Open Championship 2026: Schedule, round scores and leaderboard from Royal Birkdale ↗

The dual-conflict scenario recurs only a handful of times per year (major finals, Euros vs Ashes weekends); outside those windows the product loses its core reason to exist, limiting stickiness.The Open Championship 2026 schedule ↗
