Mobile App Development

Cybis Technologies has been designing and shipping mobile applications since 2015 — 31+ projects across 62+ clients in more than ten countries, spanning sports platforms, marketplaces, SaaS products, content apps, and field-service tools. Every app we deliver is engineered for the platform it lives on: 60 fps animations, offline support, push notifications, deep linking, biometric authentication, and submission to both the App Store and Play Store are standard deliverables, not optional extras. Whether you need a standalone consumer app or a mobile client for an existing web platform, our team handles strategy, design, engineering, QA on real devices, and post-launch maintenance.

Our portfolio spans the kinds of mobile products that generate real engagement. The PSL Matches app brings live scores, match schedules, squad pages, and push alerts to Pakistan Super League fans across iOS and Android — built alongside the web platform so data pipelines and API contracts are shared. CricketLivez extends that sports-data model to international and domestic cricket, with ball-by-ball commentary, series tables, and player stat pages optimised for low-bandwidth connections common in South Asian markets. HomeSols required a mobile client for a multi-country home-services marketplace — the app needed localised content for UAE, US, UK, and Pakistan, deep-linked service categories, and an in-app booking flow that handed off cleanly to the Laravel back end powering the web platform. Alongside these, we have shipped e-commerce shopping apps, service-business booking apps, and sports score widgets for iOS and Android home screens.

Stack decisions are made per project, not by agency default. React Native suits teams who already work in JavaScript or TypeScript, want a single codebase for two stores, and need good enough native performance for most consumer-facing features — push notifications, camera access, maps, payments, and animations all feel native in React Native when implemented correctly. Flutter is our choice when the design demands pixel-perfect custom UI that diverges from platform conventions: Dart's ahead-of-time compilation and Flutter's Skia/Impeller rendering engine deliver smooth 60 fps on both iOS and Android without the JavaScript bridge overhead. Swift and SwiftUI are reserved for iOS apps that need hardware-intensive integrations — HealthKit for fitness products, ARKit for augmented-reality experiences, StoreKit for subscriptions, Core ML for on-device inference, or CarPlay for automotive interfaces. Kotlin and Jetpack Compose handle the Android side of that same category, with the Compose UI toolkit producing declarative, themeable screens that perform consistently from budget entry-level devices to flagships.

Every engagement follows a structured process that reduces rework and keeps scope honest. Week one covers stakeholder interviews, competitive benchmarking, and a feature priority matrix that separates the MVP from the roadmap. From that we produce wireframes and then high-fidelity Figma prototypes — clickable, with real typography, spacing, and interaction states — so the design is signed off before a line of code is written. The API contract between the mobile client and the back end is designed at the same time: endpoint shapes, authentication flows, pagination, and error codes agreed upfront so iOS and Android engineers are never blocked on backend uncertainty. Development runs in agile two-week sprints with a staging build on TestFlight and Firebase App Distribution after each sprint so stakeholders can test on their own devices continuously. QA runs on real iPhones, iPads, and a device matrix of Android handsets across manufacturers and OS versions, not just simulators.

Performance is non-negotiable. We target 60 fps on the latest two iOS versions and Android versions 11 and above, with graceful degradation on older devices. Images are served in WebP or AVIF where supported, assets are code-split per screen, and list views are virtualised so memory pressure stays low even with large datasets. Offline support is implemented via SQLite, Realm, or AsyncStorage depending on the stack, with conflict-resolution logic that syncs gracefully when connectivity returns. Push notifications are wired through APNs and FCM with topic-based subscriptions, deep links that open the right screen regardless of whether the app is foregrounded or cold-started, and quiet background fetch for content apps that need data ready before the user opens the app.

Security follows industry best practice for every app regardless of sensitivity. Certificate pinning prevents man-in-the-middle interception on all API traffic. Sensitive data — tokens, credentials, payment details — is stored in the iOS Keychain or Android Keystore, never in plain SharedPreferences or AsyncStorage. Biometric authentication (Face ID, Touch ID, fingerprint) is offered as a first-class login option. All HTTP traffic enforces TLS 1.2 minimum via App Transport Security and Network Security Config. For apps handling payments we integrate Stripe's iOS and Android SDKs so raw card data never touches our infrastructure. Pair the mobile product with our web development service for a unified backend, or our SEO and ASO service to maximise visibility in both Google and the app stores after launch.

AI-powered features are increasingly a core part of mobile products rather than a differentiator. We have integrated OpenAI GPT endpoints for conversational assistants and content generation, Google Cloud Vision and AWS Rekognition for image classification and OCR, Core ML and TensorFlow Lite for on-device inference that works offline, and recommendation engines that personalise content feeds and search results against user behaviour signals. These integrations are designed with cost controls, caching layers, and fallback behaviour so the app degrades gracefully when an external API is unavailable rather than showing a broken screen.

App Store and Play Store submission is handled end to end: store listing copy, keyword research for App Store Optimisation, screenshot design matched to Apple and Google's latest guidelines, privacy manifest and data-usage declarations, age rating questionnaire, TestFlight and internal testing tracks, and final binary submission. Post-launch we monitor crash rates in Firebase Crashlytics and Sentry, review App Store and Play Store ratings, and ship maintenance releases covering OS compatibility, dependency updates, and performance fixes on a rolling retainer.
