The Real Cost of 'Free' Finance Apps: What You Actually Pay (And How That Shapes Our Pricing)

Someone has to pay for the servers. The developer hours. The database security. The audits. The support someone needs after an incident. If a finance app is entirely free for everyone and doesn't sell subscriptions, that bill gets settled somewhere else.

This post is an honest walk through where that money usually comes from, what it means for you, and why Okidoky's pricing model is deliberately structured differently.

Four business models behind "free" finance apps

1. Ad networks with behavioral targeting

The obvious one: you see ads in the app. But "advertising" is not one thing.

  • Generic banner ads (AdSense tier) typically bring in €1-5 per 1000 impressions. A small finance app earns €10-50 per 1000 active users per month from this. Not enough to fund a serious operation.
  • Behavior-targeted ads (aimed based on what you do in the app) earn 5-10× more. This means: your spending patterns are used to sell ads to parties that want to reach you.
  • Financial-product ads (loans, credit cards, investment apps) are the most lucrative — €20-100 per lead. An app can profitably redirect a user searching for "debt" to a personal-loan provider.

How to spot it: the app shows ads that feel sensitive to what you do in the app. Or you see "sponsored" financial products in menus.

2. Data sales to brokers or insurers

Less visible but often more profitable. Aggregated data ("30% of our users spend more than €500/mo on groceries in this region") gets sold to:

  • Market researchers
  • Insurers building risk profiles
  • Banks for lead generation
  • Retailers who want buying-power by postcode

The app doesn't sell your name + transactions (GDPR prohibits that), but it does sell your patterns in anonymous form that is often still re-identifiable to individuals.

How to spot it: read the privacy policy. Search for "aggregated data", "partners", "third parties for analytical purposes". If it says "we may share aggregated data with third parties", this is the model.

3. Cross-sell to their own financial products

Some "free" apps are effectively lead-gen fronts for a broader financial product portfolio. Bunq does this, for example: you get budgeting free, but the real product is the bank account. The US-based Credit Karma (now owned by Intuit) did this with credit-card and loan recommendations.

This model is relatively transparent: you usually know you're at a bank or financial service provider. The question is: can you see the budgeting function as genuinely separate from the sales funnel? Sometimes yes, sometimes not really.

4. "Freemium" with essentials behind the paywall

Technically not a "free" model — it's a free entry-point with a paid upgrade. The question is whether the free version is usable enough to actually work with, or purely a demo of the paid version.

How to spot it: can you budget meaningfully for a year with the free version? Or do you hit artificial limits within two weeks? (E.g. export blocked, history capped at 30 days.)

Why we deliberately do it differently

Okidoky explicitly follows none of the first three. Concretely:

No behavioral ads. The only ads free users see are generic banner ads (AdSense tier, from non-personal context). No targeting on your spending, no financial-product leads.

No data sales. Not to brokers, not to insurers, not to banks. Our privacy policy is explicit on this. If we ever wanted to change that, it would have to be an opt-in choice per user — and as long as we stay bootstrapped, the incentive to go down that path isn't there.

No cross-sell to financial products. We have no payment account, credit card, investment, or insurance to redirect toward. We are just a ledger. And will stay that way.

Yes to freemium — deliberately chosen. We run a real free version (50 transactions per month, 3 months of history) and a paid Premium (€1.50/mo). The free version is meant to be usable for a year for people with simple spending patterns. Premium is for those who want more, and the price is low enough that it shouldn't form a barrier.

Why this is relevant for your choice

If you're picking between two ledger apps of comparable features, the question "how is this funded?" matters more than the feature list. Because the business model determines:

  • Whether your spending patterns are processed for purposes outside your account
  • Whether the app will be forced in the future to change things (acquisition, funding round, pivot)
  • Whether financial products you didn't ask for will start coming at you
  • Whether the privacy policy will still say the same thing in three years

Three questions that help you pick

For any finance app:

  1. Where does the money come from? Subscriptions, ads, data sales, cross-sell, bank ownership? More than one at once? Read the privacy policy and search for "aggregated", "third parties", "partners".

  2. What is the free version set up to do? Does it work as a separate usable product, or is it a trailer for the paid version?

  3. Who owns the app in 5 years? Is it bootstrapped with a clear owner, or is there VC funding that will force an exit?

Okidoky is bootstrapped, free to try, and has an explicit list of what we will never do. Premium €1.50/mo or Lifetime €25.
