iOS app development cost for finance & fintech

There is no single figure, and quoting one would be the least useful thing this page could do — the same pairing spans several-fold depending on scope, compliance and how many surfaces you ship. What this page gives you instead is what the pairing demands: the regimes that may apply, the systems of record you will be asked to integrate with, the device matrix and the release path. The calculator below is already fixed to iOS and finance & fintech — answer what is left and it returns a cost range, hours, timeline, team and running costs for your scope.

Because finance & fintech brings its own obligations before you write a feature: SOC 2 Type II, PCI DSS, GLBA Safeguards Rule may apply, you will be asked to integrate with systems like Plaid / MX and Stripe, and there are typically 6 distinct roles rather than one. The platform contributes its own separate costs — the device matrix, App Store review — and those are independent of the industry.

Slightly, and almost entirely because of testing. The engineering itself is comparable, but iOS has a handful of screen sizes and two or three OS versions in play, versus 20–30 meaningful Android configurations. That difference is typically 30–50 hours per release cycle. Against that, iOS adds App Review as a schedule dependency and a $99 annual account, and requires Mac hardware to build on.

Budget one to four days per submission and expect at least one rejection on a first release. The common causes are predictable and worth designing around up front: no in-app account deletion, offering third-party sign-in without Sign in with Apple, unclear subscription pricing, and privacy labels that do not match actual data collection. Each round trip costs a day or two, so a first submission three days before a launch date is a real risk.

Three reasons, in order of cost. First, correctness: a ledger that must reconcile to the cent needs idempotency, settlement handling and daily reconciliation that a normal CRUD app does not. Second, identity: KYC, sanctions screening and fraud scoring are a subsystem, not a feature. Third, evidence: audit logging, access reviews, retention control and SOC 2 artefacts are continuous engineering. None of it is user-visible, and all of it is mandatory.

Usually, and it will save more than any engineering decision you could make. Using a sponsor bank, a licensed banking-as-a-service provider or Stripe Treasury keeps the regulated activity on their licence rather than yours. This changes your product architecture substantially, so decide it before you build. Talk to fintech counsel early — it is the cheapest hour on the project.
