Envelope autopilot
Keep every dollar pointed at a job. Flexible envelopes mirror the YNAB flow, yet respond instantly when your reality shifts.

Built by budgeters who swear by YNAB, FYN brings the same zero-based rigor to a calmer, more collaborative workspace. Plan true expenses, respond to life, and keep decisions transparent with everyone who shares your money story.



YNAB taught us to give every dollar a job. FYN keeps that habit alive with automation that still respects the ritual.
Keep every dollar pointed at a job. Flexible envelopes mirror the YNAB flow, yet respond instantly when your reality shifts.
Line up renewals, rent, and savings targets in one forward calendar so your future-self always knows what is already funded.
Invite a partner, roommate, or accountability buddy. Real-time sync keeps conversations calm and centered on agreements.
Three steps, all guided inside FYN.
Import securely from any bank or type fast with keyboard-first entry. FYN automatically proposes envelopes based on your rules.
Prioritize true expenses, then let funding recipes backfill the rest. Visual tension bars show when a category drifts off mission.
Guided review prompts nudge you through wins, tradeoffs, and what to roll with. It feels like the calmest YNAB check-up ever.
