Demand
4/10

Royal-watching is a real but narrow niche — royal.uk itself labels its engagement calendar 'The Royal Diary' and Hello Royal Club runs a 'Royal Diary' weekly column, showing audience appetite, but Google Trends ~200/GB for the polo cup keyword signals modest search volume.The Royal Diary | The Royal FamilyRoyal Diary: What's coming up this week

Whitespace
6/10

No dedicated consumer 'royal engagement planner' app exists; closest are the official royal.uk future-engagements database and the Royal Family Tree genealogy app (App Store), leaving room for a planner-style product but news outlets and Hello cover most content free.Royal Family Tree - App StoreUpcoming Royal Events - Unofficial Royalty

Monetization
5/10

Majesty Magazine has sold monthly subscriptions for 45+ years in 50+ countries, proving willingness to pay for premium royal content, but the pool of paying royal superfans is small and ad-supported/impulse-IAP for a tracker app is unproven.Majesty Magazine - The Quality Royal MagazineMajesty Magazine Subscription

Longevity
5/10

The British monarchy endures but engagement schedules shift with reigns (e.g., Prince William succeeding the King), and core engagement data is controlled by the official palace, creating a dependency risk for a third-party diary app.The Royal Diary | The Royal Family

Feasibility
7/10

Calendar/countdown/notes/photo features are commodity app building blocks, but sourcing and rights-managed image data plus keeping engagements fresh against the official 8-week rolling window add ongoing operational work.The Royal Diary | The Royal Family
