Android applications
Kotlin and Java, plus C#, Python, and Lua where the product already lives there. Enterprise, startup, and consumer apps. UI/UX, secure integrations, performance work, and Play Store delivery.
Mobile Application Development
Native, Flutter, and hybrid apps that survive the store, the network, and the second year.
Android, iOS, Flutter, hybrid, and Angular mobile — plus the games, on-demand, POS, and field apps that sit on top of them. Swift, Kotlin, Dart, Cocoa Touch, and Cordova in production. We have shipped EasySail for marine navigation and AIS tracking, retail POS mobile, taxi and service booking, and Flutter products that share one codebase across Android and iOS.
Intro & problem space
A mobile app fails in public. App Store review, Play Console, background location, payments, push, and the device that has 12% battery and a 3G radio in a tier-2 city. Hybrid wrappers that looked cheap at kickoff become unmaintainable. Native teams that cannot share code miss the window. Founders who wanted “an Uber for X” discover that dispatch, payments, and driver/provider apps are three products, not one screen.
Geek Theory builds mobile as an engineering surface, not a design showcase. That includes consumer Android and iOS, Flutter cross-platform, hybrid when the web team must own the client, Unity games, and the mobile half of on-demand, food, events, and retail POS. The constraint is always the same: the app has to work on the device the user actually holds, talk to a real backend, and stay shippable after Apple and Google change the rules.
Capabilities
What We Build (Consolidated Capabilities)
Android product types we already scope
chat, VoIP, multimedia, utility, custom business, and augmented reality clients.
iOS applications
Swift and Objective-C on Cocoa / Cocoa Touch. Interactive products, stores, and App Store-grade performance under Apple’s review bar. Experience across iOS 13–17 class OS targets.
iOS specialty clients
Bluetooth and iBeacon, AR, multimedia, meeting software, ecommerce, manufacturing-floor companions, and data-extractor companions.
Flutter / Dart
one codebase for Android and iOS, Flutter web when the same product must run in a browser, custom widgets, plugins, templates, dashboards, and hybrid shells that still feel native. Planning, UI/UX, agile Flutter development, performance testing, and dual-store deployment.
Hybrid app development
Cordova / PhoneGap, Appcelerator Titanium, Corona SDK, jQuery Mobile, and Flutter-as-hybrid when you need one team to reach both stores without two native codebases.
Angular mobile / hybrid
AngularJS-class mobile apps for organisations standardised on Angular on the web.
Progressive Web Apps as a mobile channel
installable, offline-capable web apps when a store listing is optional and the business is still web-led. (Full PWA engineering lives with Website Development; here it is the mobile distribution choice.)
Game development
Unity, 2D, mobile games, Android 2D, simulators, AR games, pre-production, design, analytics, talent/ops tooling around the title, and launch. Millennial-flat and discussion/team game surfaces included where the brief is social, not only arcade.
On-demand taxi booking apps
rider, driver, and admin; payments; live tracking; analytics. The three-sided marketplace, not a map demo.
On-demand service booking apps
customer, provider, and admin; CMS; automation; auth/payments; ROI instrumentation.
Food ordering mobile
ordering, branch operations, user remarks, and the customer app that sits on the food-ordering platform.
Event booking mobile
attendee and admin, ticket flows, insights, and event operations on device.
Retail POS mobile
the store in the owner’s pocket: POS, inventory, and customer acquisition on top of the cloud POS.
EasySail-class field apps
marine navigation, AIS tracking, route monitoring, emergency alert handling, encrypted auth, and location used for the job, not for harvesting.
Notifications, payments, and AI features on mobile
push, PayPal/Razorpay-class gateways, and on-device or API-backed AI where the product needs it.
Hire mobile developers
dedicated Android, iOS, Flutter, and hybrid engineers on the same engagement models as web.
Delivery
Our Process
-
01
Discover
Who holds the phone, which stores, offline/location/payment constraints, and whether native, Flutter, or hybrid is an engineering decision or a political one.
-
02
Architect
Client stack (Swift/Kotlin vs Dart vs Cordova), backend contracts, push, maps, payments, and the admin that operations will actually use.
-
03
Prototype
Device-real UI, empty states, permission flows, and the one journey that must not drop (booking, checkout, navigation, or dispatch).
-
04
Engineer
Native or Flutter implementation, plugin work, store compliance, backend integration, and game/AR loops if that is the product.
-
05
Deploy
TestFlight / Play internal testing, review, signing, and a release train that can ship a hotfix after rejection.
-
06
Scale
Crash analytics, store optimisation, Flutter/web companions, and the second platform only after the first is stable.

Why Geek Theory
Mobile at Geek Theory is not a separate boutique. The same engineering company that builds the Laravel or Node backend builds the Flutter or Swift client, the POS handheld, and the taxi driver app. EasySail is the standard we hold: location is a feature with a privacy policy, not a tracking add-on. Hybrid is a cost decision we will defend or refuse. Unity is in the house for games; we will not pretend a WebView is a game engine.
Next step
Start a Mobile App Project
Bring the platform target, the offline/location/payment constraints, and whether you need one codebase or two native teams. We will tell you which is cheaper over 24 months, not over the first sprint.
