Native iOS fintech app development

Using Swift, SwiftUI, and Combine while fully leveraging Apple’s latest frameworks, we build secure, high-performance native iOS apps that fintech leaders can confidently scale. Our team knows its way around Face ID, NFC-based tap-to-pay and card scanning, encrypted Keychain storage, and Core ML for on-device intelligence. Beyond coding, *instinctools helps fintech clients simplify KYC, ensure PSD2 and GDPR compliance, and pass Apple’s App Review on the first try.

Native Android fintech app development

Our team excels at delivering intuitive, user-friendly apps that perform well and look good regardless of the device brand, screen size, or Android version. We gear your app to detect tampering, nip fraud in the bud, and sync financial transactions smoothly even under battery-saving restrictions. Due to our comprehensive experience in Google Play’s privacy framework and fintech industry standards, you sail through certifications and updates without a hitch.

Cross-platform development

For startups and fast-growing fintechs who need to launch fast, we build Android and iOS apps in parallel, using Flutter or React Native. This cuts development time and costs while ensuring feature parity: a single codebase means fewer mismatches and bugs, making maintenance easier. We still deliver near-native performance and consistent UI/UX that looks great and feels smooth across devices.

  • Flutter mobile development services


    If you’re looking to accelerate time-to-market and save on development and testing, Flutter is the ideal choice. With a single codebase for both iOS and Android, backed by Google and a global community, we’ll help you bring your ideas to life faster and more efficiently.

  • React Native development services


    Achieve affordable cross-platform compatibility and faster speed-to-market by reusing up to 90% of the codebase between Android and iOS. Powered by a mature, widely supported framework, React Native helps you deliver high-performance mobile apps that reach a broader audience with less effort.

Progressive Web Apps (PWAs)

Looking to launch a new fintech app quickly and efficiently? Our PWA development services are built for exactly that. Deliver native app-like experiences, minus the app store friction. Reach users in emerging markets, even on slow networks or low-end devices. All while keeping development costs down by ditching the need for multiple codebases.

Hybrid fintech mobile apps

Prototypes of simple fintech services or internal tools can be built very quickly thanks to our hybrid fintech app development know-how. We leverage our web development expertise to wrap your web application into a responsive mobile solution. This is ideal for content-heavy or internal apps like bank employee portals or support tools where speed and functionality matter more than cutting-edge UX. Moreover, with instant web code updates, it’s easy to push fixes without App Store delays.

The expectations for the quality of the initial product were very high. I think *instinctools did a great job ensuring those expectations are met. We met the developers we were going to be working with and it quickly became apparent that they are very qualified and were able to deliver the vision that we had from our side for the product. They clearly told us what they were going to do, and if there were questions or problems along the way, they clarified them really quickly thanks to transparent communication.

Deif
Jeanine Shepstone
Senior Technical Writer

Instinctools is good at understanding the technical issues – once an issue is outlined, they do not need repeated explanation. They also do not simply accept a proposed solution, but they think about it and propose a better solution. I was really impressed by the custom interface they built for us – we outlined the requirements, and they implemented them in a user-friendly way that makes the interface a pleasure to use.

Sebastian Belle
VP of Engineering

Instinctools does deliver on time and budget. The company proactively asks how they can support our efforts and provide ideas how to help us with very good candidates with expertise that either we requested or that instinctools identified to be missing.

Alisa Delikatna
COO

The team demonstrated effective project management, timely delivery, and responsiveness to our needs. They established open communication to facilitate ongoing dialogue and held regular sprint meetings to keep stakeholders informed and engaged throughout the development process.

FAQ

How long does fintech app development take?

Based on our experience, low-to-medium-complexity projects usually take 3 to 6 months. Still, it’s the development approach and the specific functional and non-functional requirements that lay out the timeline. If the logic grows more complex and the scope of features, integrations, and certifications widens, each development stage tends to drag out.

How much does it cost to develop a fintech app?

Price swings with complexity, features, and compliance demands. A basic fintech app kicks off around $70,000, while fully loaded, sophisticated fintech solutions climb into the high six figures. We prepare budget estimates tailored exactly to your unique business blueprint and technical vision, so you’ll have complete clarity and no surprises when it comes to your project’s cost.

Do you recommend native or cross-platform fintech software development?

Native development hands you superior performance, UX, and security, while cross-platform allows for faster delivery and lower costs, which is ideal for MVPs or simpler fintech apps. Each approach has its strengths, but the final choice is something we help you make after a sharp look at your goals, timeline, and budget.

How can I hire your app developers for fintech software development?

As soon as you submit your request, we get a clear read on your preferred tech and communication skills, team size, rates, and more. With company-level and personal NDAs signed to guard your privacy, we quickly put forward a curated shortlist of candidates. Once you’re confident in the team and terms, we ink the deal and get started.

How do you protect sensitive financial data during app development?

We put obligatory data encryption in place, follow industry standards like GDPR and PCI DSS, implement role-based access control, conduct regular security audits, and follow through with secure coding practices. Keeping financial data locked down tight is built into every step of our development process.
