Six Roadblocks We Remove From Your App

Most mobile apps launch fine. The trouble starts later, when users, systems and rules change faster than the app can keep up.

  • Apps Cut Off From Core Systems
  • Two Codebases, Double Effort
  • Outdated UX Users Abandon
  • Apps Left Alone After Launch
  • Traffic Growth Breaks Backend
  • Manual Steps Slow Onboarding
Icon: mobile app cut off from core banking and record systems
An app that cannot reach the core banking, records or order system in real time shows stale data and sends customers back to branches and call centers.
“Customers see yesterday’s balance, so they call us to check it.”

Two Codebases, Double Effort
Two Codebases, Double Effort
Separate iOS and Android apps drift apart. Every feature is built, tested and fixed twice, and one platform always ships later.

“Android is always two releases behind iOS, and users notice.”

Outdated UX Users Abandon
Outdated UX Users Abandon
An interface designed years ago turns simple tasks into long journeys. Ratings fall and users switch to a competitor before they complain.

“Our store rating dropped below four stars in one quarter.”

Apps Left Alone After Launch
Apps Left Alone After Launch
New operating system versions, security patches and store policy changes arrive every year. Without an owner, crashes pile up and releases stop.

“Every new iOS version breaks something, and the original vendor is gone.”

Traffic Growth Breaks Backend
Traffic Growth Breaks Backend
A single backend sized for launch slows down as users and services grow, and every new feature risks breaking an old one.

“Every salary day the app slows down and support lines fill up.”

Manual Steps Slow Onboarding
Manual Steps Slow Onboarding
When staff check documents by hand, digital sign-up can take two to five days, and many new customers never finish.

“New customers wait two days for someone to check their ID.”

Mobile App Development Services
For Every Stage of Your App's Growth

Build, connect, scale and support: four delivery areas with AI built into each, run by teams who know the rules of banking, healthcare and retail.

Mobile App &
Product Development

4 mo Idea to
launch

Native iOS and Android apps, cross-platform builds and progressive web apps, from discovery and UX design to the first store release, with AI features built into the app and AI-assisted design, coding and testing behind it.

Solves - Two Codebases, Double Effort. Separate iOS and Android teams ship the same feature twice and never at the same time. Choosing the right approach up front, and letting AI agents support coding and testing under human approval gates, keeps both stores in step.
Mobile App & Product Development
What we deliver
Native iOS & Android Cross-platform apps UX/UI design AI-powered app features

System Modernization
& Integration

300K+ Records
migrated

Rebuild aging apps and connect them to core banking, health record, payment and partner systems without stopping the service customers rely on, with AI-enabled engineering to speed up modernization and QA.

Solves - Apps Cut Off From Core Systems. Customers see stale data because the app waits for a nightly update. Real-time connections to the core system show every balance, order and booking as it changes, and make that data available to AI features in the app.
System Modernization & Integration
What we deliver
Real-time APIs Legacy app rebuild Data migration AI-assisted modernization

Enterprise Platform
Development

192 Branches on
one platform

The platform behind the app: independent backend services, security gateways, and data pipelines and APIs ready to serve AI models such as eKYC, chat and recommendations to a growing user base.

Solves - Traffic Growth Breaks Backend. One backend slows down at every peak and each new feature risks breaking an old one. Independent services scale on their own, so AI features can be added and scaled without taking the app down.
Enterprise Platform Development
What we deliver
Microservices backend Security gateway AI-ready data & APIs Cloud setup & scaling

Managed
Services

24/7 Standby
support

Monitoring, maintenance, operating system updates and store releases that keep apps stable and secure under ISO 27001 and ISO 9001 certified processes, plus AI managed services that keep the AI in your app accurate after go-live.

Solves - Apps Left Alone After Launch. Each new operating system version breaks something and nobody owns the fix. A support team watches crashes, ships updates and runs security audits on a set schedule, and monitors AI models for performance and cost.

24/7 monitoring Store releases & OS updates Security audits AI model monitoring

AI That Cuts Wait Time and Costs

Four ready-built Savvycom AI solutions that plug into new or existing mobile apps through SDKs and APIs, each removing a step users wait for or repeat.

24/7 Answers, Fewer Tickets

Forms Filled From a Photo

Forms Filled From a Photo

Frequently Asked Questions

Common questions from teams evaluating a mobile app development partner in Vietnam.

How much does it cost to build a mobile app with Savvycom?

Dedicated teams and staff augmentation are billed monthly per engineer: mid-level developers from $22 to $34 per hour, senior from $24 to $38, tech leads from $27 to $44 and AI/ML engineers up to $55. Fixed-price apps are quoted after a one to two week discovery. Full rate ranges are on our IT outsourcing page.

How long does it take to build and launch a mobile app?

A focused consumer or patient app typically takes three to five months from idea to store release. Savvycom delivered the diaB diabetes app in four months. Enterprise apps that connect to core banking or records systems take longer because of integration and security testing; we agree the timeline after discovery.

How do you build a mobile banking app that connects to the core banking system?

We design the integration layer first: secure APIs to the core banking platform, biometric sign-in, transaction limits and audit logging, then build the app on top. For a Cambodian bank serving 192 branches, Savvycom migrated more than 300,000 records from the legacy app and relaunched without interrupting customers.

Should we build a native app or a cross-platform app?

Cross-platform frameworks such as Flutter and React Native cover most business, banking and health apps with one codebase for iOS and Android, which cuts build and maintenance effort. We recommend native development when the app depends on device hardware, heavy graphics or platform-specific security features. We assess this choice in the first week of discovery.

Can you build healthcare, fitness and wellness apps?

Yes. Savvycom has built the diaB diabetes management app, the Wanna Train fitness platform, the Kokkiri meditation app and an AI chatbot for a mental health platform used by more than 20,000 people. Health apps are built with data protection and consent flows designed in from the start.

What happens after the app is launched?

Launch is the start of the engagement. Savvycom handles app store updates, OS compatibility, monitoring and bug fixes under a monthly support plan, and the same team can add features or AI assistants later. If you move development in-house, we hand over source code, documentation and store accounts. We also build the web platforms behind many apps.
