FlightyFlow
A competent developer can reproduce the core flight-tracking features in about a week using available open-source projects; the App Store polish, native Live Activity integration, and subscription/Apple-specific distribution are what you'd lose.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All FlightyFlow alternatives, with the arithmetic →
What a replacement has to do
- User adds flight by number+date → system queries flight-data providers → store and monitor flight state → push notifications for changes → display flight on interactive map and timeline.
What it still won’t have
- Polished native iOS UI/animations and App Store polish
- Built-in subscription handling and App Store in-app purchases flow
- Priority support and curated content
- Any proprietary historical data or backend optimizations not documented on the App Store page
- Apple Live Activities lock-screen integration (would require native iOS work)
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
FlightyFlow does not publish a price we could read, so there is nothing to compare against. What building costs is below.

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal flight-tracking service using Next.js for the frontend, Node/Express backend, Postgres for storage, and a worker (BullMQ) for scheduled polling. Core features in scope: flight lookup by number+date (uses a third-party flight-data API), background status polling every 15 minutes with change detection, push notifications via APNs, interactive map view using Mapbox or Leaflet, and a travel timeline. Out of scope: App Store in-app subscription integration, advanced analytics, and multi-platform native apps. Include error handling, rate-limit/backoff for API calls, unit and integration tests, Dockercompose for local dev, and deployment scripts for a single small VPS (DigitalOcean) and documented steps to add a flight-data API key and map key.
How we checked
How the score was reached
- Build verdict base78
- An open-source build was found+5
- 2 cited sources+1
- Evidence score84
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
