Ionic development company
We build Ionic apps with Angular, React or Vue on Capacitor, ship them to the App Store, Google Play and the web, and tell you plainly when an app’s demands point to React Native, Flutter or fully native code instead.

Ionic apps that feel at home on phones
For teams with web skills who need iOS, Android and browser versions of the same product, Krapton is an Ionic development company that builds all three from one codebase. Ionic Framework supplies mobile UI components as web components that adapt to iOS and Material Design styling, and Capacitor wraps the app in a native shell with plugins for the camera, push notifications, biometrics, filesystem and secure storage. The approach fits forms, dashboards, field-service tools, booking flows and content apps, especially when a web team already exists. It fits poorly for graphics-heavy games, complex gesture-driven interfaces or apps that depend on long-running background work, and we say so during scoping. Our engineers keep the WebView fast with lazy-loaded routes, virtualized long lists and lean bundles; store tokens in the iOS Keychain or Android Keystore rather than localStorage; and treat the ios and android folders as source code, reviewed and versioned like everything else. Releases run through Fastlane or CI with signing, privacy manifests and Android target API levels kept current.
Ionic development services
Cross-platform Ionic app builds
Ionic apps in Angular, React or Vue with platform-adaptive styling, tab and stack navigation, offline storage through SQLite, and one codebase shipping to iOS, Android and the web.
Cordova to Capacitor migration
Moving legacy Cordova apps onto Capacitor, replacing abandoned plugins with maintained equivalents, committing native projects to source control, and fixing build issues in Xcode and Gradle along the way.
Custom Capacitor plugins
Swift and Kotlin plugins when no maintained plugin exists, for Bluetooth peripherals, payment terminals, background location or vendor SDKs, with a typed JavaScript API and web fallbacks.
Ionic upgrades and modernization
Upgrading older Ionic Angular apps to current Ionic and Angular versions, adopting standalone components, removing deprecated APIs and replacing removed components such as the old virtual scroll.
Performance and UX tuning
Profiling the WebView with Safari Web Inspector and Chrome remote debugging, then cutting bundle size, virtualizing long lists, fixing layout thrash and smoothing transitions on mid-range Android devices.
Store release and compliance
App Store and Google Play submissions, signing and provisioning, privacy manifests, data safety forms, APNs and FCM setup, and deep links through Universal Links and Android App Links.
Why teams choose Krapton for Ionic
Senior engineers, fixed scope, and code you own — the things agencies promise and rarely deliver.
Maintainable by your web team
Because Ionic code is standard Angular, React or Vue, your web developers can maintain the app afterwards, with native expertise needed only for plugins and store releases.
Native code when it is needed
Engineers comfortable in Swift and Kotlin write or patch plugins themselves instead of waiting on an abandoned community repository to fix a crash.
Plugins vetted before adoption
Every Capacitor or Cordova plugin is checked for recent releases, open crash issues and support for current iOS and Android versions before it enters your app.
One codebase, three targets
The same Ionic app serves as a PWA and as store apps, with platform checks isolating native-only features so the web build does not break when a plugin is unavailable.
How a Ionic project runs with Krapton
01
Feature and device spike
Risky native features are prototyped on physical devices first, confirming plugin support, performance and store-policy implications before design is finalized.
02
Design for both platforms
Screens are designed with iOS and Material conventions in mind, including safe areas, back-button behavior on Android and keyboard handling on forms.
03
Build and test
Features ship with unit tests, Playwright or Cypress flows against the web build, and device checks before each sprint demo.
04
Release and monitor
Signed builds go to TestFlight and Play internal testing, then production, with crash reporting, analytics consent handling and a plan for OS updates.
The Ionic stack we build with
Ionic development: questions answered
Is Ionic good enough for a production mobile app, or should we go native?
Yes for most business apps; native or another framework is better for demanding interfaces. Ionic handles forms, lists, dashboards, booking and content apps well, especially when performance basics such as lazy loading and list virtualization are in place. Games, AR, heavy animation, complex gestures or long-running background tasks push toward Swift and Kotlin, React Native or Flutter. A short device spike on the riskiest feature settles the question with evidence.
Who handles App Store and Google Play releases when we hire an Ionic development company?
The development team should, as part of the scope rather than an afterthought. That covers signing certificates and provisioning profiles, APNs and Firebase Cloud Messaging setup, privacy manifests and Play data safety declarations, deep links, review rejections, and yearly Android target API updates. It also includes plugin maintenance when iOS or Android releases break something, and monitoring crash reports after each release.
How do you migrate an old Cordova or Ionic 3 app to Capacitor?
In stages, starting with the build and plugins rather than the UI. We add Capacitor alongside the existing project, audit every Cordova plugin, keep those that work under Capacitor and replace abandoned ones with maintained alternatives. If the app is on an old Ionic Angular version, the framework upgrade happens in steps, fixing breaking changes at each one, with smoke tests on devices before moving forward.
How do you make an Ionic app feel fast on Android devices?
By treating the WebView like a constrained browser. Routes are lazy-loaded so startup only parses what the first screen needs, long lists are virtualized, images are sized and lazy-loaded, and animations stick to transform and opacity so they stay on the compositor. We profile through Chrome remote debugging on mid-range phones, not just flagships, and check startup time against the splash screen hand-off.
What determines the cost of an Ionic app?
The native feature list matters most, because that is where Ionic estimates move. Standard Capacitor plugins for camera, push and storage keep effort modest, while custom Swift and Kotlin plugins for Bluetooth, payments or background location add native development and device testing. Offline sync with conflict handling, user roles, backend work if no API exists, accessibility requirements and a companion PWA also shape the estimate.
