Fintech & Finance

We offer PCI-DSS readiness support as part of every payments build, helping you get ready for a PCI-DSS audit before it happens. We haven't completed a PCI-DSS-audited case study yet, so we're upfront about that: we help you get ready, we don't claim a certified audit we haven't done. We're also HIPAA and GDPR verified, and we build to whatever compliance standard your specific fintech or banking project actually requires.

Fintech mobile app development at New York App Devs runs on a fixed-price model agreed before work begins, so the number you sign off on is the number you pay. There's no published hourly rate, because every banking, payments, or lending app is scoped around what your business actually needs. A simple balance-check app costs less than a full payments platform with fraud detection and compliance tooling. You can get a real ballpark for your specific project through our Instant Estimate tool, which asks about platform, app type, complexity, and screen count. Getting an exact number always requires a short scoping call with our team.

There's no single timeline that fits every banking, payments, or lending app, because scope varies too much project to project. What's fixed is the delivery rhythm: development runs in 1 to 2 week sprints, with a working build delivered incrementally so you can test the real app yourself every cycle. Once development wraps, deployment covers App Store and Google Play submission, screenshots, metadata, and handling any review rejection or resubmission, before your app goes live.

Yes. Our office is in Midtown Manhattan, at Americas Towers, 1177 6th Ave, 5th Floor, New York, NY 10036. We're a local, hands-on build partner, not a national call center or an offshore team with a local-sounding name. If you'd rather talk through your fintech project in person, you can stop by, call, or book time with a real member of our New York team directly.

Three things: a fixed-price model with no surprise invoices, weekly sprint demos so you see a working fintech mobile app build every cycle instead of one reveal at the end, and 100% code ownership once the project's complete. We're also a DesignRush-recognized Top Mobile App Development Agency (2025), HIPAA and GDPR verified with PCI-DSS readiness support, and based in Midtown Manhattan, not an offshore team operating under a local-sounding name.
