CashSDKCashSDK
For travel apps

Monetize the trip, the booking, and the price freeze.

Travel apps run three revenue models at once — recurring Pro tiers like AllTrails+ and Flighty Pro, à-la-carte flexibility add-ons like Hopper’s Price Freeze, and seasonal one-off unlocks. CashSDK ships all three from one integration, with paywalls you A/B over the air and revenue you can read the same afternoon you launch.

Subscriptions · à-la-carte add-ons · seasonal offers — one SDK, both stores.

How the category prices

Three revenue models, running at the same time.

The top travel apps stack recurring Pro subscriptions, à-la-carte flexibility add-ons sold at checkout, and seasonal one-off unlocks — each targeting a different moment of the trip. Here is how the category really charges.

Recurring

Pro subscriptions

The revenue base: a free app to browse and organize, then an annual Pro tier that unlocks offline access, live alerts, and predictions.

  • AllTrails+ ~$35.99/yr; AllTrails Peak ~$79.99/yr (AI tier, 2025)
  • Flighty Pro ~$59.99/yr (~$4.99/mo) or ~$299 lifetime
  • TripIt Pro ~$49/yr — Seat Tracker, fare-refund monitor
  • Gates offline maps, live delay alerts, predictions; 7-day trials

À la carte

Flexibility add-ons

Per-booking, insurance-like SKUs sold at the moment of anxiety — Hopper's signature. Priced dynamically per trip, non-refundable, framed as peace of mind.

  • Price Freeze — small deposit (~$1–40 flights, ~$16+/night hotels)
  • The deposit credits toward the booking if you buy
  • Cancel / Leave for Any Reason (~$30–44) — 80–100% back
  • Price Drop Protection is free — pays out in store credit

Hopper

Seasonal & one-off

Seasonal upsells & unlocks

Physical goods and one-time unlocks that ride the trip's calendar — booked in bursts around each traveler's season, not on a monthly clock.

  • Polarsteps prints Travel Books (~$40–165, à la carte)
  • Polarsteps Plus ~$29.99/yr; posters ~$29 each
  • PackPoint Premium ~$2.99 one-time unlock — no subscription
  • Rome2Rio is ad- & affiliate-commission funded — no paid tier

Paywall shapes

Every travel paywall, rendered from our own components.
