Mobile app development is the process of strategizing, designing, building, and launching applications for iOS and Android devices. Moddtech helps companies decide whether a mobile app is the right investment, then plans and ships the experience that earns a permanent place on users' home screens.
Who it's for
Founders deciding whether to build an app at all, product teams planning a first mobile launch, and established businesses extending a web platform or replacing a legacy native app. Anyone who wants the strategic question answered honestly before writing a check.
  • Validate whether a mobile app is the right investment before you spend
  • Choose the right approach — native, cross-platform, or PWA
  • Sequence platforms (iOS, Android, web) based on your audience data
  • Ship products users actually open more than once
  • Build for retention, not just downloads
Process

How it works, step by step

01
Strategy & Validation
Stakeholder interviews, user research, and competitive analysis. We decide whether a mobile app is the right investment before any code is written.
02
Platform Strategy
Native vs cross-platform vs PWA, iOS vs Android sequencing, monetization model, and feature scope. Strategic recommendations based on your audience and business model.
03
Design & Prototype
User flows, UX architecture, and high-fidelity designs in Figma. Interactive prototypes for stakeholder review and user testing before development begins.
04
Build & Test
Sprint-based development on the chosen stack. Internal QA plus TestFlight and Play Console beta testing on real iOS and Android devices.
05
Launch & Iterate
App Store and Google Play submission, launch monitoring, and post-launch iteration based on user behavior, retention data, and feedback.

FAQ

Questions we hear most often.

Should I build a mobile app at all?

Maybe. Mobile apps make sense when your product needs offline access, native device features (camera, GPS, push notifications), high-frequency engagement, or stronger brand presence than a website provides. They don't make sense for occasional-use products or content that works fine in a mobile browser. We help clients decide honestly — including telling you not to build one when that's the right answer.

Native app, cross-platform, or PWA — which is right?

Native (Swift, Kotlin) delivers maximum performance and platform integration but roughly doubles cost. Cross-platform (Flutter, React Native) ships to both stores from one codebase at lower cost — best for most use cases. PWA (Progressive Web App) skips the app stores entirely and runs in the browser — best when discoverability and zero install friction matter more than native features.

Should I launch on iOS or Android first?

Depends on your audience. iOS users skew higher income, urban, and U.S. or Western European. Android dominates globally and has roughly 70% worldwide market share. B2B apps often launch iOS-first. Consumer apps depend on demographics and geography. We help validate with real audience data before you commit.

How much does a mobile app cost?

MVP apps generally start in the mid-five-figure range. Full-featured consumer or B2B apps typically run low to mid six figures. Enterprise apps with deep backend integration can exceed that. Most teams underestimate post-launch cost — ongoing maintenance, OS updates, and iteration typically run 15-25% of build cost annually.

How do you measure app success?

Beyond installs: D7 retention (do users come back after a week), D30 retention, session depth, and feature adoption. For monetized apps, conversion to paid and lifetime value. Vanity metrics like total downloads tell you nothing if nobody opens the app twice.

What happens after launch?

The real work. Apps that succeed get continuous iteration based on user behavior and feedback. We offer ongoing development retainers covering bug fixes, OS updates, feature additions, and analytics review. Apps without ongoing investment decay fast — within 18 months they often stop working on the latest OS version.

Build the right thing first

The hardest question in mobile is the one most teams skip: should you build a native app at all? A bad native app costs six figures and gets deleted after one use. A great mobile-responsive site can handle 80% of use cases without install friction. We help you decide before you commit.

Strategy before code

Native app, hybrid app, progressive web app, mobile-responsive site, or some mix? Each path has different costs, capabilities, and constraints. We start with your business goals, user research, and competitive landscape to recommend the approach that fits — not the one that bills the most consulting hours.

Platform sequencing matters

iOS first, Android first, or both at once? The right answer depends on audience demographics, monetization model, and team capacity. Get this wrong and you waste months building for the smaller half of your market. We help sequence platforms based on data, not assumption.

Designed to be opened twice

Most apps fail not at launch but at retention. The download is easy; the second open is hard. We design for retention from day one — onboarding flows, push notification strategy, content depth, and the unique mobile capabilities that justify being on a home screen instead of just a bookmark.

Ship, learn, evolve

Apps are never finished. Launch is the start of iteration: monitoring, learning, refining. We build with that reality in mind — clean architecture for fast iteration, instrumented for analytics from day one, and a backlog framework so post-launch development doesn't stall.
