It's Not Techy
App DevelopmentUpdated April 2026

Mobile & Web App Development

Ship polished apps, faster.

iOS, Android, and web apps built on React Native, Swift, Kotlin, and modern stacks.

What it is

Sometimes a website isn't enough. We design and build native and cross-platform apps — from MVPs to at-scale products — with the same discipline we bring to marketing sites.

Why it matters

  • Mobile apps drive 3x higher conversion rates and 4x higher purchase-per-visit values than mobile web for ecommerce and services brands (Criteo Shopper Story; App Annie / data.ai).
  • App users have 3–4x higher retention at day 90 than web-only users for the same brand — apps compound engagement over time (Adjust Mobile App Trends Report).
  • Average time spent in apps reached 5 hours per day per user in 2024 — more than every other digital surface combined (data.ai State of Mobile Report).

Outcomes

  • Shipped product
  • Higher retention
  • Growth loops

Who this is for

Growth-stage teams that want app development treated as a discipline — not a side project. You have a real business to grow, budget to deploy thoughtfully, and an exec team that wants answers in numbers.

When you'd hire us

  • Launching a new brand, product, or market.
  • Current results are plateauing and you need a reset.
  • You need senior thinking without hiring a full-time team.

Engagement shape

Standalone sprint, multi-month program, or embedded team — you pick what fits. Fixed-fee sprints start small; programs scale with scope; embedded engagements run on a monthly retainer.

What you get

How we're different

App Development is a noisy space. A few things we believe — and push back on — that shape how we run every engagement.

What most agencies do
  • Sell you a fixed template and adapt your business to it.
  • Hand the work to juniors after the pitch.
  • Report on vanity metrics that don't tie to revenue.
  • Lock you into proprietary tools you can't take with you.
  • Chase shiny tactics without a durable strategy.
What we do instead
  • Build a app development system tuned to your P&L.
  • Senior practitioners on every call, every week.
  • Report on pipeline, revenue, CAC, LTV — not impressions.
  • All files, data, and docs live in your accounts. No lock-in.
  • Strategy first. Tactics second. Always in that order.

FAQs

Do you do ASO (App Store Optimization)?+

Yes. ASO is to apps what SEO is to websites — keyword research, listing copy optimization, screenshot and video A/B testing, review velocity management, and category selection. Apple Search Ads and Google UAC integration for paid amplification. Most of our app-development engagements include an ASO layer at launch.

Which platforms do you build for?+

iOS (Swift, SwiftUI), Android (Kotlin, Jetpack Compose), and cross-platform (React Native, Expo, Flutter). We pick the stack based on performance requirements, team composition, and feature complexity — React Native works for 80% of use cases; native is the right call for graphics-intensive or deeply platform-integrated products.

How do you handle post-launch growth?+

Post-launch, we run ASO, push notification strategy, in-app experimentation via Amplitude or Statsig, growth-loop design, and App Store featured-placement pitches. The engineering of the app is 40% of the work; the other 60% is the growth system around it.
