Our App Development Services

Our App Development Services

From native mobile to progressive web apps and AI-integrated platforms, OTT engineers and markets your app as a complete revenue engine.

iOS App Development

We build Swift and SwiftUI applications that meet Apple’s latest Human Interface Guidelines and pass App Store review on the first submission. Our iOS apps are engineered for performance, accessibility compliance, and the on-device AI capabilities unlocked by Apple Intelligence in 2025-2026.

  • Swift and SwiftUI for iPhone and iPad
  • Apple Intelligence and Core ML integration
  • Push notifications, in-app purchases, and subscription monetization
  • App Store submission, review management, and ASO launch
  • Accessibility (WCAG 2.2 AA) compliance built in
Android App Development

Our Kotlin and Jetpack Compose team delivers high-performance Android applications that scale across the fragmented Android device landscape — from budget handsets to foldables and Chromebooks. We optimise for Google Play’s ranking algorithms from the first build.

  • Kotlin and Jetpack Compose for phones, tablets, and foldables
  • Google ML Kit and Gemini API integration
  • Material Design 3 UI/UX that converts
  • Google Play Console management and pre-launch testing
  • Adaptive layouts for every screen size and density
Cross-Platform App Development React Native Flutter

When budget, timeline, or market reach demands a single codebase that runs on both iOS and Android, React Native and Flutter are the right tools — in the right hands. OTT’s cross-platform engineers have shipped dozens of apps with native-level performance and zero compromise on user experience.

  • React Native with Expo and bare workflow options
  • Flutter with Dart — ideal for pixel-perfect custom UIs
  • Shared business logic, platform-specific UI polish
  • OTA (over-the-air) update capability with CodePush
  • 40-60% faster time-to-market vs. two native builds
Progressive Web Apps PWA Development

Progressive Web Apps are the bridge between web and mobile — installable, offline-capable, push-notification-enabled, and crawlable by search engines. For businesses that cannot afford separate web and app teams, a PWA is often the highest-ROI decision in 2026, especially given Google’s continued preference for fast, mobile-first experiences in organic rankings.

  • Service worker architecture for offline functionality
  • Web App Manifest for home-screen installation
  • Core Web Vitals optimisation baked in (LCP, INP, CLS)
  • Push notification support across browsers and OS
  • SEO-friendly architecture that ranks in Google and AI search
AI-Integrated App Development

The apps that will dominate in 2026 and beyond are not just well-designed — they are intelligent. OTT integrates large language models, computer vision, recommendation engines, and predictive analytics directly into your app’s core user flows. We work with OpenAI, Anthropic, Google Gemini, Meta LLaMA, and custom fine-tuned models depending on your product’s needs.

  • LLM-powered chat, search, and personalisation features
  • Computer vision for image recognition, AR overlays, and scanning
  • Recommendation engines that increase session depth and revenue
  • Voice UI and natural language processing
  • On-device AI for privacy-first, low-latency experiences
Common Questions

Frequently Asked Questions About App Development

Answers to the questions we hear most

How much does it cost to build a mobile app with OTT?

App development costs vary significantly based on complexity, platform, and feature set. A focused MVP (Minimum Viable Product) for a single platform typically starts at $25,000–$50,000. A full-featured, dual-platform (iOS + Android) app with AI integration and ASO launch support generally ranges from $80,000–$250,000+. OTT provides detailed scoping and fixed-price proposals after the initial discovery phase, so you always know your investment before committing.

How long does app development take?

A well-scoped MVP typically takes 12–16 weeks from signed contract to App Store submission. Cross-platform apps using React Native or Flutter can shave 4–6 weeks off this timeline compared to building two separate native apps. Complex AI-integrated products may require 20–30 weeks for a production-ready v1. OTT provides a detailed project timeline in the proposal phase, with sprint milestones you can track in real time.

What is App Store Optimisation (ASO) and why does it matter?

ASO is the practice of optimising your app’s store listing — title, subtitle, keyword fields, description, screenshots, preview videos, and review responses — to rank higher in App Store and Google Play search results and convert more browsers into installs. In 2026, over 65% of app discoveries still happen through in-store search. Without ASO, even a great app remains invisible. OTT integrates ASO strategy from the very beginning of development, not as a post-launch patch.

What is GEO for apps and why should I care in 2026?

Generative Engine Optimisation (GEO) for apps means structuring your web presence, app content, and brand authority so that AI-powered search engines — Google AI Overviews, ChatGPT search, Perplexity, Gemini — recommend your app in their generated answers. With AI search handling over 40% of informational queries by mid-2026, being surfaced in AI answers is becoming as important as ranking on page one. OTT is one of the only agencies that approaches app marketing with a dedicated GEO strategy layer built in.

Should I build a native app or a cross-platform app?

The right answer depends on your product’s performance requirements, budget, and time-to-market goals. Native iOS and Android apps deliver maximum performance and access to platform-specific APIs but cost more and take longer when built separately. React Native and Flutter cross-platform apps share up to 90% of code, significantly reducing cost and timeline, while delivering near-native performance for the vast majority of use cases. OTT recommends native for apps that require intensive graphics processing, complex device hardware integration, or are competing in categories where milliseconds of performance matter. We recommend cross-platform for most business apps, marketplaces, and service-based applications.

Can OTT help market my existing app, not just build a new one?

Yes. OTT provides standalone ASO audits and ongoing ASO management, app-specific SEO campaigns, content marketing programmes targeting app keywords, and link building campaigns for app landing pages. If you have an existing app that is underperforming in stores or not generating organic installs, OTT’s growth team will identify the gaps and build a structured improvement plan. Our SEO and content teams have the capacity to run parallel campaigns across your web and mobile presence simultaneously.

Do you offer post-launch support and maintenance?

All OTT app projects include a 30-day post-launch bug-fix warranty period at no additional cost. Beyond that, we offer structured retainer plans covering OS version updates, feature additions, ongoing ASO refinement, and integrated SEO content campaigns. Most clients opt for ongoing growth retainers because app success is iterative — the highest-performing apps in any category release updates monthly and continuously optimise their store presence and marketing funnel. OTT’s 96% client retention rate reflects the ongoing value we deliver after launch.

What industries has OTT built apps for?

OTT has delivered app projects across e-commerce and retail, healthcare and wellness, financial services and fintech, real estate, hospitality and travel, on-demand services, legal, education, media and entertainment, and B2B SaaS. Our 1,000+ client base spans 70+ countries and over 50 verticals, which means whatever your industry, OTT has encountered — and solved — the category-specific challenges your app will face. We bring cross-industry learnings that pure-play development agencies cannot offer.

Why App Development Is Business-Critical in 2026

Why App Development Is Business-Critical in 2026

Mobile apps are no longer optional. In 2026, the global app economy exceeds $935 billion in annual revenue, and AI-native applications are rewriting how consumers interact with every industry — from e-commerce and healthcare to finance and on-demand services. Brands that built marketing-ready apps in the last five years now dominate their categories. Those that waited are fighting for scraps.

But here is the problem most app agencies will not tell you: a beautiful app that nobody can find is just expensive software. Most app development shops are full of engineers and zero marketers. They ship a product to the Apple App Store or Google Play with zero App Store Optimization, no SEO architecture baked in, and no GEO (Generative Engine Optimization) strategy for the AI discovery era.

At Over The Top SEO, we build apps the other way around. Growth strategy comes first. The code follows. Guy Sheetrit — featured in Forbes, Inc., and the New York Times — built OTT on one principle: digital assets must generate measurable returns. That principle now drives every app we ship.

  • Over 20 years of combined digital marketing and product development experience
  • 1,000+ clients across 70+ countries trust OTT for their growth
  • 96% client retention rate — the highest in the industry
  • Apps built with ASO, SEO, and AI discovery baked in from day one
  • Full-stack teams: developers, UX designers, SEO strategists, ASO specialists under one roof

The OTT Advantage: Marketing-Ready from Day One

The OTT Advantage: Marketing-Ready from Day One

The OTT Advantage: Marketing-Ready from Day One

Most app development agencies hand you an APK and a Figma file and call it done. OTT does not work that way. We are fundamentally a growth company that builds apps. That distinction changes everything about how your product is architected, named, described, and launched.

When Guy Sheetrit founded Over The Top SEO, the core insight was simple: digital presence without visibility is worthless. That same philosophy now applies to app development. An app without discoverability is an expensive liability. Our cross-functional teams — developers, SEO strategists, ASO specialists, content marketers, and UX researchers — collaborate from the first sprint, not after launch.

  • Brand and keyword strategy defined before a single line of code is written
  • App name and metadata engineered for App Store and Google Play search algorithms
  • Landing page SEO built in parallel with app development — see our SEO services
  • Content marketing roadmap ready for launch day — backed by our content marketing services
  • Link building campaign targeting app-related authority — powered by our link building services
  • Local SEO integration for location-based apps — via our local SEO expertise

The result: your app launches with a distribution strategy already in motion, not as an afterthought six months post-launch.

OTT App Development Marketing Results

App Store Optimisation (ASO) + SEO Integration

App Store Optimisation (ASO) + SEO Integration

The App Store and Google Play are search engines. Like Google, they reward relevance, authority, and conversion signals. ASO is the discipline of optimising every metadata field, screenshot, preview video, and review response to maximise your app’s ranking and install conversion rate. OTT has managed ASO for apps across every major category — productivity, e-commerce, health, finance, gaming, and B2B SaaS.

But ASO alone is no longer enough in 2026. With AI-powered search (Google AI Overviews, Perplexity, ChatGPT search) now surfacing app recommendations to users who never visit an app store, your web presence directly drives app installs. OTT bridges ASO and SEO so your app is discoverable everywhere your users search — including AI-generated answers. This is what we call Generative Engine Optimisation (GEO) for apps.

  • App title, subtitle, and keyword field optimisation for both stores
  • Screenshot and preview video A/B testing for higher conversion
  • Review generation strategy and reputation management
  • Localisation for 70+ country markets and languages
  • Web-to-app SEO funnel: landing pages, blog content, and schema markup
  • GEO-ready content that trains AI models to recommend your app
  • Integration with our full web design services for seamless brand consistency
