Personal cashflow planner: what is safe to spend

A personal cashflow planner across several accounts and currencies. It answers four questions: how much is available, how much is reserved, how much is safe to spend, and which account runs short and when. I have been rewriting it since 2013 — PHP, then Symfony with Vue, now Next.js with an Expo iOS client; the web app is live, the iOS app is in TestFlight only.

Detail

It is deliberately not accounting: transfers between your own accounts never count as income, and net worth matters less than which account runs short, and when.
