Mobile Apps that fits how your business runs
Mobile apps live or die on the details: cold start time, offline behaviour, push notifications that arrive when they should, and a release process that does not break with every OS update. We design and build apps that handle those details properly, whether the right answer is Swift and Kotlin for a native experience or React Native and Flutter to reach both platforms from one codebase.
Most mobile products are really three things: the app, the API behind it and the admin tools around it. We build all three together so data models, authentication and analytics are consistent from day one. Secure storage, biometric login, deep links, background sync and accessibility are handled as standard features rather than afterthoughts.
We build apps for healthcare, logistics and retail use cases where reliability matters more than novelty. You get senior mobile engineers, a shared design system across iOS and Android, automated builds through TestFlight and Google Play, and support through store review and the first releases after launch.
Why teams choose Nexlantic for mobile apps
One codebase, both stores
React Native and Flutter let one team ship iOS and Android together, with native modules where a feature needs platform-specific performance.
Works offline
Local storage, queued writes and conflict handling keep field and clinical apps usable when connectivity drops, syncing cleanly when it returns.
Secure on the device
Encrypted storage, certificate pinning, biometric authentication and session controls protect data on phones that leave the building.
Store-ready releases
Automated builds, crash reporting and release checklists get you through Apple and Google review and keep updates flowing afterwards.

Our mobile apps process
Four focused stages, each with a clear deliverable and a decision point for your team.
- 01
Platform decision
We weigh audience, device features and budget to choose native, React Native or Flutter, and define the API the app will need.
- 02
Prototype on device
Clickable prototypes run on real phones early so navigation, gestures and performance are validated before the full build.
- 03
Build and test on hardware
Features are developed with automated and manual testing across OS versions and screen sizes, with beta builds to your testers.
- 04
Release and iterate
We manage store submission, monitor crashes and usage after launch, and plan the next releases from real data.

Mobile Apps questions, answered
Still unsure? Book a 30-minute call and we will walk through your situation.
It depends on the product. Cross-platform frameworks like React Native and Flutter suit most business and consumer apps and halve the maintenance burden. Native Swift or Kotlin is worth it when you need deep hardware access, heavy graphics or platform-specific features.
Yes. We typically deliver the app, the API and an admin dashboard as one project so authentication, data models and analytics stay consistent. If you already have an API we integrate with it and extend it where needed.
We prepare listings, screenshots and privacy declarations, submit builds through your developer accounts, and respond to review feedback. After approval we set up automated releases so updates ship without manual steps.
Sensitive data is encrypted at rest on the device and in transit, sessions expire sensibly, and biometric login is available where appropriate. For healthcare apps we design to HIPAA requirements and keep protected health information off the device wherever possible.
