Fintur

The finance app that shows tomorrow, not just yesterday.

Comment

Inspiration

Every budgeting app I'd tried told me the same story: what I'd already spent. Great for a post-mortem, useless for a decision. I'd open my bank app the night before payday, do mental math on whether I could afford something, and get it wrong half the time because I'd forgotten a subscription renewal or an insurance payment sitting three weeks out. The question I actually wanted answered was never "what happened," it was "what's coming, and can I afford this thing I'm about to do."

That gap became Finsee's whole premise: stop showing people yesterday, start showing them tomorrow.

What it does

Finsee connects to your bank (read only, via the regulated DSP2 provider Powens, so it's physically incapable of moving money) and projects your balance forward day by day, not just this month, but as far out as your income and known expenses reach.

Four tabs carry that idea:

  • Summary: your whole financial situation and your Finsee Score (a one-glance health check) on a single screen.
  • Calendar: every euro gets an arrival date and a departure date, so upcoming charges stop being surprises.
  • Finsee AI: ask it in plain language, "what if I go on a trip in March?", and the projection curve answers back.
  • Horizon: your projected end-of-month balance, visible from today.

The core feature is decision simulation: before you buy a car, book a trip, move apartments, or start saving, Finsee compares your current trajectory against the hypothetical one, automatically folding in the hidden costs people forget (insurance, maintenance, fuel), and gives you a plain verdict: within your means, or not. It's the difference between hoping you can afford something and knowing.

Free users get the full app with a 45-day projected horizon. Finsee Premium (monthly or annual, powered by RevenueCat) unlocks the full daily projection and the advanced AI simulations. No ads, no data resale, ever.

How we built it

The app is SwiftUI, targeting iOS 26, using the new Liquid Glass design system end to end rather than faking a glass look with blur and opacity. Typography is Manrope throughout, tightly controlled with fixed sizing to stay pixel-accurate to the original design references.

RevenueCat sits behind every Premium decision in the app: applies the premium entitlement everywhere balances need to be shown or blurred.

Bank data comes from Powens (DSP2-licensed, EU-hosted), wired through Supabase Edge Functions so the OAuth client secret never touches the client. Manual entry is always available for anyone who'd rather not connect a bank at all.

The whole product is localized into 8 languages (French, English, Spanish, Dutch, Italian, German, European Portuguese, Hindi) from a single source-of-truth string catalog, with every user-facing string routed through one localization helper, no hardcoded copy anywhere in the UI.

Challenges we ran into

Getting bank connectivity to production was its own project: DSP2 compliance, webhook verification, and making absolutely sure a secret that should never leave the server never did.

Accomplishments that we're proud of

Powens bank connectivity has been live in production since the debut of August, real accounts, real transactions, real projections. RevenueCat drives a fully working freemium model end to end, from the paywall to entitlement-gated blurring of locked data. The app ships in 8 fully, humanly reviewed languages, not machine translation dumped into the catalog.

What we learned

Where to draw the free/Premium line matters more than how you draw it. Forty-five days of projected horizon for free was chosen deliberately: enough to prove the "see it coming" idea is real and useful, not so much that Premium feels optional. Getting that number right took several passes.

We also learned that in personal finance, trust is a feature you build in architecture, not copy. Read-only bank access and "we will never move your money" only mean something because the DSP2 integration is actually incapable of doing otherwise, and that had to be true before it could be marketed.

What's next for Finsee

Android is next (currently "coming soon" on Google Play), bringing the same projection engine to a much larger audience. Beyond that: deepening Finsee AI so simulations feel less like a form and more like a conversation, and expanding the Premium tier as the projection and simulation engine keeps getting smarter.
