Fintech & Wallet AppsBuilt for Money, Secured for Trust

Short answer: Fintech and wallet app development builds secure iOS and Android apps for payments, accounts, balances and transactions, where strong authentication, encryption and secure design are the core requirement, not an add-on. Built in React Native, one codebase serves both platforms while reaching native secure storage, biometrics and device security features. These apps integrate regulated providers — banking, card-issuing and payment APIs — that handle money movement and compliance, so the app never stores raw financial credentials. Our Houston team designs, builds and maintains fintech React Native apps in-house.

Fintech & Wallet App Development in Houston

In a fintech app, trust is the product. Users hand over the most sensitive thing they have — access to their money — so biometric login, encrypted storage, session security and a clear, honest UX aren't features you bolt on later; they shape every screen. A wallet, a payments app, a budgeting or account app has to feel fast and simple on the surface while being rigorous underneath: secure token storage, certificate pinning, careful handling of every balance and transaction.

React Native fits because it reaches native security primitives — the iOS Keychain, Android Keystore, Face ID and fingerprint — from one codebase across both platforms, and we drop into Swift or Kotlin for anything the framework can't reach securely. Critically, we build fintech apps on top of regulated, PCI-compliant providers for payments, banking data and card issuing, so money movement and sensitive credentials live with the provider, not in your app. That keeps your compliance surface smaller and your users safer.

A Houston-based team gives you one group accountable for a domain where mistakes are expensive — from secure architecture and provider integration through launch and the ongoing updates security demands. We build the app, integrate the right regulated partners, and stay on to keep dependencies patched and the app hardened as threats evolve. Note that we build and secure the software; we are not a licensed financial or investment advisor, and regulated activities remain with your compliant provider.

FAQ

Fintech & wallet app questions

How much does a fintech or wallet app cost?

Most fintech React Native apps land between about $30,000 for a secure MVP on top of a payments provider and $120,000+ for a full product with KYC, card issuing and banking data. One codebase serves both iOS and Android, avoiding two native builds. Use the estimator above for an indicative range, then book a free call for a firm quote.

What is a fintech or wallet app?

A fintech or wallet app is a mobile app for payments, accounts, balances or transactions where security and strong authentication are core to the design. It typically sits on top of regulated, PCI-compliant providers that handle money movement and sensitive credentials, so the app delivers a simple experience while the heavy compliance lives with the provider.

How long does it take to build a fintech app?

A secure fintech MVP typically ships in 2.5–4 months, since integrations and security testing add time over a standard app; a fuller product runs 5–8 months. We build in 1–2 week sprints with security reviews baked into each release.

How do you keep a fintech app secure?

We threat-model the design, store secrets in the iOS Keychain and Android Keystore, use biometrics and MFA for auth, pin certificates, encrypt data in transit and at rest, and keep dependencies patched. We also build on PCI-compliant payment and banking providers so raw financial credentials never live in the app itself.

Do you handle the money movement and compliance directly?

No — and that's by design. Money movement, card issuing and KYC run through regulated, licensed providers such as Stripe, Plaid or Marqeta, which hold the compliance. We build and secure the app that integrates them; we are not a licensed financial or investment advisor, so regulated activity stays with your compliant partner.

Can you add biometric and multi-factor login?

Yes. We implement Face ID and fingerprint unlock, secure token storage, and multi-factor authentication using native device security, so users get fast sign-in without weakening protection on a device holding their money.

Do you work with businesses outside Houston?

Yes. We are based in Houston, TX and have delivered 700+ projects internationally over 20+ years, working with local and remote teams across the USA and worldwide.

Do you offer fintech app development in Houston?

Yes. We are based at 9800 Richmond Ave in Houston (Westchase / Energy Corridor) and build fintech and wallet apps for Houston businesses locally as well as clients nationwide and internationally.
