Anviam is a mobile app development company that builds native iOS and Android apps, React Native and Flutter cross-platform products, and progressive web apps, the kind our own SWIPEBY and FLEX products run on every day.

Native iOS app development and native Android app development give you the best performance and full access to the camera, sensors and background processes on each platform, though you're maintaining two separate codebases. React Native and Flutter share most of that code across both platforms, which usually means a shorter timeline and lower cost, without giving up a native look and feel.
A progressive web app is a third option worth considering: it installs from a browser, works offline and sends push notifications, without an app store review in the way. As a progressive web app development company, we'll recommend whichever of the three actually fits your users and your budget, not whichever we'd rather build.
As an ios app development company and android app development company under one roof, we scope every build around your platform, budget and timeline instead of a one-size-fits-all package.
Swift-based apps built for the App Store, with full access to iOS frameworks, ARKit and platform-specific interactions.
Kotlin-based apps built to handle the wide range of Android devices in the market and Google Play's review requirements.
One shared codebase shipping to both iOS and Android, with native modules bridged in wherever performance demands it.
Installable, offline-capable web apps for teams who want app-like reach without an app store dependency.
Rebuilding or re-platforming existing apps stuck on outdated frameworks, poor performance or high crash rates.
Store listing copy, screenshots, submission handling and post-launch monitoring across both major app stores.
Real-time order tracking and dispatch, the same category our own SWIPEBY curbside pickup product runs in.
Route optimization, live location and job status tracking for teams working outside an office, the model behind FLEX's live tracking.
Secure account access, payments and transaction history built to bank-grade authentication standards.
Patient intake, video consults and appointment scheduling inside HIPAA-compliant mobile workflows.
Contactless ordering and pickup notifications, built on the same pattern proven out in SWIPEBY.
Shift scheduling, inspections and field reporting tools built for employees rather than public app stores.
We map your users, features and budget to decide native, cross-platform or PWA before any design starts.
Wireframes and clickable prototypes validate the flow before a single line of app code is written.
Sprint-based development against your backend, payment providers and third-party APIs.
Testing across real device and OS combinations, not just simulators, before anything ships.
Store listing prep, submission handling and monitoring through the first weeks after launch.
It depends on what the app needs to do. Native iOS and Android give you the fastest performance and full access to platform-specific features, which matters for camera-heavy, AR or high-performance apps. React Native or Flutter let you share most of the codebase across both platforms, which usually cuts cost and timeline by 30 to 40% for apps that don't push hardware limits. We'll tell you honestly which fits your case rather than defaulting to whichever we'd prefer to build.
A progressive web app, or PWA, is a website that behaves like an app: it can be added to a home screen, work offline, and send push notifications, without going through an app store. It's a good fit if your users mostly access you through a browser already, or if you want app-like reach without the App Store and Play Store approval cycle. It's not a substitute for a native app when you need deep device integration like Bluetooth or background GPS tracking.
A focused MVP with core features usually takes 8 to 12 weeks. A full-featured app with backend integrations, payments and admin tooling typically runs 14 to 20 weeks. Cross-platform builds with React Native or Flutter tend to land at the shorter end since one codebase covers both iOS and Android.
Yes. We prepare the store listings, screenshots, privacy disclosures and build signing, and manage the submission and review process on both the Apple App Store and Google Play Store. If a submission gets rejected on review feedback, we handle the resubmission as part of the engagement.
In most cases, yes. We start by auditing the current codebase, crash logs and store ratings to see whether the issues are architectural or fixable. Apps built on outdated frameworks, with poor crash rates or slow load times, often just need targeted re-platforming rather than a full rebuild from zero.
Yes. Beyond fixed-scope app builds, you can hire React Native developers from Anviam as a dedicated, embedded extension of your team on a monthly staff-augmentation model, working directly in your sprints and tooling.
