The market
Hopper earns from bookings rather than subscription and TripIt sells a paid tier. Trip planning monetises through transactions more reliably than through monthly fees, and this charges $5 per trip costed rather than a monthly fee.

Why this audience
Family trips are the largest discretionary purchase most of these households make in a year, and the cost is guessed at until the credit card statement arrives. This audience is already trying to work out whether a trip is doable. A full number before booking is the answer to a question they are actively asking.
Before it can launch
No licence, certification or data agreement stands between this and a launch — app-store review and an ordinary privacy policy aside.
What it earns

0.043% of 2.3M followers · capped at 50,000
Opens on the price this idea was costed at, $5.
A quarter is one purchase every four years; twelve is monthly.
1,000 paying — 0.043% of 2.3M followers — × $5 × 3 purchases a year = $15,000 a year
Fifty thousand paying users is the ceiling every one of these pages is drawn against, not a forecast. It opens at a thousand, the bottom of the range, so the first figures you see are the modest ones. What the cap buys is comparability: the same range on every app, and the percentage of the audience it takes as the number that moves.
