Know your burn.
Own your future.
Flint tracks every recurring income and expense, shows exactly how close you are to financial independence, and keeps all of your data encrypted on your device.
Every number that matters
for financial independence
Your burn rate
Rent, subscriptions, groceries — every recurring expense normalized to a monthly rate so you can compare apples to apples. Tag discretionary spend separately to see your lean-FI number vs. full coverage.
Your income streams
Paychecks, side hustles, dividends — anything coming in on a cadence. Mark each stream as active or passive with a single toggle. See your total monthly inflow at a glance.
FI coverage arc
A single arc fills as your income covers your burn. Set your target multiple — 1× for break-even, 1.5× for the common FI buffer, 25× for full FIRE — and watch it fill over time.
Cashflow calendar
See every payment and deposit projected across the month. Spot coverage gaps before payday, not after. Filter by income or burn, discretionary or essential.
Dividend tracking
Add a ticker to any holding and Flint auto-fetches its real payout history — no broker login. Shares × payout rolls straight into your income, and cut & hike alerts flag changes as they happen.
Tax buckets
Tag every income stream as taxable, tax-deferred, or tax-free, and see your income split cleanly across the three. Your coverage arc can exclude money you can't touch yet — like a 401(k) — so you know what's actually accessible today.
Multiple profiles Premium
Keep your financial lives apart — your own money, the household, a side business — each with its own items, accounts, and FI target.
- Separate books — personal spending never mixes with the household's.
- One tap to switch — a profile chip at the top of every screen.
- Independently encrypted — each profile is its own encrypted database.
Household sharing Premium
Share a profile with your partner and Flint keeps both phones up to date automatically. Add a bill on your phone; it shows up on theirs.
- Two-way sync — adds, edits, and deletes carry across both phones.
- One purchase covers the couple — your partner rides free.
- Direct & private — encrypted peer-to-peer, no cloud or account.
Your data stays on your phone
Flint has no backend and no accounts. Your financial data lives in an encrypted database on your device. The optional partner sync sends data directly between your phones over an encrypted peer-to-peer connection — never through a server, never to us.
