Market watch + journal · white-label source licence
A market-watch and trading journal, under your name
CryptoChallenge tracks prices, keeps a personal trading journal, and fires price alerts to iPhone and Apple Watch - all backed by a small server you run yourself. It never places a trade or connects to a brokerage. License the source, rebrand it with one config file, ship it as your own. By Roger Maragh.

A real screen from the iPhone app, on a server with no account connected: the prices and signals are live public quotes. Click it to see it full size.
What you get
iPhone app
Dashboard, journal, watchlist and alerts - the whole client, tested with a real unit test suite.
Apple Watch + widgets
A Watch app and complications, plus a Home Screen widget - all synced through your own server.
The server
Python/Node backend: market data, preferences sync, push notifications, and a private web dashboard.
Never places trades
Information only, by design - no brokerage connection anywhere in the app, which keeps App Store review simple.

- You need your own always-on server. This is not a purely offline app - the iPhone app syncs to a server you run continuously, reachable from the internet. Budget real infrastructure time for this, not just a rebrand.
- Market data comes from free public endpoints, which are not licensed for a commercial product - license a real feed before selling access as a paid product.
- A research and journaling tool, not investment advice. It places no trades and promises no returns.
- The app ships under your own Apple Developer account; App Store review is between you and Apple.
