OBDX mobile app development
OBDX mobile app development — custom Flutter, React Native & native apps on Oracle Banking Digital Experience.
Appsarmy builds the mobile app layer on top of Oracle Banking Digital Experience (OBDX). Custom Flutter, React Native, and native iOS and Android apps against the OBDX servicing application and its APIs — with deep OBDX integration experience, not an implementation partner. We have taken an OBDX-based retail banking app to production for a GCC retail bank, delivered in phases against a live rollout. It is a specialist corner of our fintech app development practice.
Custom OBDX mobile apps, in the framework you need.
OBDX ships a hybrid app, but a bank that wants a first-class native experience needs a custom client against the OBDX APIs. We build that client in Flutter, React Native, or native — and, more importantly, we own the integration underneath it.
Custom OBDX mobile apps
A first-class OBDX mobile banking app in Flutter, React Native, or native Swift and Kotlin — built against the OBDX servicing application rather than skinning the shipped hybrid app. One team covering all three approaches, so the framework follows your product and your bank's team, not ours.
Our mobile craftOBDX API integration
The real work: device and push registration, RSA challenge-response login, session and cookie lifecycle, and OTP reconciliation across the app, the servicing layer, and the core. Plus the architectural call — remote UI served by OBDX versus UI hosted locally in the app, decided per screen.
Integration is the credentialAuth & security
Push-notification 2FA, passkey passwordless login, certificate pinning, and force-update — the OBDX security surface, done properly.
Channels & UX
Deeplinking, scan-to-pay, home-screen widgets, and MUNIS multi-language delivery — the app features customers judge a bank on.
ODA chatbot & AI
In-app ODA chatbot inclusion, plus the AI layer — document intelligence and fraud signals — on top of the OBDX data.
The auth flow is where OBDX mobile gets hard.
The OBDX mobile work banks actually need.
OBDX and FLEXCUBE are deployed at banks across the GCC, the wider MENA region, and Africa — markets such as Libya, Sudan, Senegal, Nigeria, Algeria, Djibouti, and Malawi — as well as parts of Asia and Europe. We build the custom mobile layer for banks across these regions.
OBDX retail mobile banking
Accounts, transfers, cards, and servicing in a custom native app on OBDX — the pattern behind the OBDX-based retail app we took to production for a GCC retail bank, delivered in phases against a live rollout.
Servicing-app extension & customization
Extending the OBDX servicing application and its APIs with custom journeys — part of a wider digital transformation without re-implementing OBDX or touching the core. New screens, new flows, same system of engagement.
Remote UI vs local UI decisions
The real architectural call, made per screen: render remote UI served by OBDX for governed consistency, or host the UI locally in the app for speed, animation, and offline resilience. We make it deliberately, not by default.
Authentication & session hardening
Device registration, RSA challenge-response, cookie and session lifecycle, OTP reconciliation, SSL certificate pinning, and force update — the OBDX security surface built to a bank's audit bar.
Passwordless, push & scan-to-pay
Passkey passwordless login, push-notification 2FA, deeplinking, home-screen widgets, and scan-to-pay — the modern channel features on top of the OBDX foundation.
MUNIS multi-language delivery
Multi-language apps delivered through OBDX's MUNIS framework — Arabic and RTL included — so one app serves a bank's whole customer base across a region.
The integration is scoped before the screens.
OBDX discovery
Your OBDX version, deployment, and which APIs are exposed — and where the servicing app already does the work versus where a custom client must.
Auth & session design
Device and push registration, RSA challenge-response, and the cookie and session lifecycle mapped end to end before a screen is built.
Remote vs local UI
A per-screen decision on remote UI versus locally hosted UI, so consistency and speed are traded off deliberately, not by accident.
Build
Flutter, React Native, or native delivery in short cycles, against the OBDX APIs, with a working build each sprint.
OTP & pen test
OTP reconciled across app, servicing layer, and core, then independent penetration testing and certificate-pinning verification.
Phased cutover
Released in phases against a live rollout, with force update and push registration proven before the bank switches customers over.
The OBDX mobile stack we build on.
Mobile-layer specialists, not an implementation partner.
We do the mobile layer
We are not an Oracle partner and not an OBDX implementation partner. We do not license or implement OBDX — we build the custom mobile client on top of your existing deployment, which is a niche almost nobody serves.
Deep OBDX integration experience
The credential is specificity: RSA challenge-response, cookie and session lifecycle, OTP reconciliation across the stack, and the remote-vs-local UI call. We have solved these on a real OBDX deployment, not read about them.
Proven on a live core
We took an OBDX-based retail banking app to production for a GCC retail bank, delivered in phases against a live rollout — the pattern we bring to banks across the GCC, MENA, and Africa.
Senior-led, NDA-first
Senior engineers on every call, strict IP protection, and direct access — the way banks and their implementation partners expect a mobile vendor to work.
Work with us the way that fits.
OBDX mobile assessment
A fixed engagement that reviews your OBDX version, APIs, and auth model, and returns a mobile architecture and remote-vs-local UI plan you can fund.
Fixed-scope OBDX app
A defined custom app on OBDX — Flutter, React Native, or native — written scope, clear price, phased against your rollout.

Augment your team or your implementation partner with senior OBDX developers who know the servicing app, the APIs, and the auth flow.
OBDX mobile app development questions.
Can OBDX mobile apps be built in Flutter?
Yes. OBDX exposes REST APIs and a servicing application, so a mobile client can be built in Flutter, React Native, or native Swift and Kotlin — not only the shipped hybrid app. We handle device registration, RSA challenge-response, session lifecycle, and OTP so it behaves like a first-class native app.
Flutter, React Native, or native for OBDX?
All three integrate the same way, through the OBDX APIs, so the choice is about your team and product. Flutter is our default; React Native suits a React web team; native fits deep-platform features. We cover all three and help you choose on fit.
Do you replace the OBDX servicing app or extend it?
We extend it. The OBDX servicing application stays the system of engagement; we build the custom mobile client against it and decide, per screen, remote UI versus locally hosted UI. The core stays untouched.
How does OBDX authentication work in a custom app?
Device and push registration, then RSA challenge-response establishing a cookie-carried session, with OTP or push-notification 2FA on sensitive transactions — reconciled across the app, the servicing layer, and the core. Passkeys and certificate pinning sit on top.
Are you an Oracle or OBDX implementation partner?
No. We are not an Oracle partner or an OBDX implementation partner and do not license or implement OBDX. We specialise in the mobile app layer on top of an existing OBDX deployment, with deep OBDX integration experience.
Which markets do you build OBDX mobile apps for?
Banks across the GCC, the wider MENA region, and Africa, plus parts of Asia and Europe, where OBDX and FLEXCUBE are deployed. We have taken an OBDX-based retail app to production for a GCC retail bank, phased against a live rollout.
