Setup

Connection, preferences, backup, and the checks that tell you whether anything here can be trusted.

Price data provider — the reliable way

Free public relays throttle and stall, which is why prices have been unreliable. A proper data provider answers this page directly, needs no relay, and covers SGX as well as US. A free account takes about a minute and is enough for a portfolio this size.

Provider Your free API key

Twelve Data: sign up at twelvedata.com, the free plan gives 800 lookups a day. Finnhub: finnhub.io, free plan covers US shares. The key is stored only in this page and only on your device.
