01 · BUILD

Mobile app development that ships on time and survives the App Store.

Native iOS and Android development — or cross-platform with React Native — designed and engineered by a senior team that’s shipped dozens of apps to production. We handle everything from initial discovery to App Store and Google Play submission, working with clients across multiple time zones.

  • UX research + user testing
  • Full Figma prototype
  • iOS + Android engineering (Swift / Kotlin / React Native)
  • Backend API + database setup
  • QA, testing, App Store submission

Key benefits

Pricing decisions backed by data

We benchmark your category and target markets, model competitive pricing, and test before we commit. Pricing that works in the US often fails in Brazil; we plan for that.

Paywalls designed to convert, not just exist

Most apps treat paywalls as an afterthought. We treat them as a product surface — designed, tested, and iterated.

Subscription expertise

If your app should be subscription-based, we'll structure tiers, trials, and intro pricing the way our own subscription apps do — which earn six and seven figures annually.

Ad yield without the user-experience tax

If ads make sense, we'll set up mediation properly — maximising eCPM without ruining retention.

Our process

Discovery (Week 1-2)
Category benchmarking, monetization model selection, pricing structure design — accounting for purchasing power across your target markets.
Implementation (Weeks 3–4)
Paywall design and build, subscription/IAP setup, analytics integration.
Launch & test (Month 2)
Initial paywall live, A/B test queue running, first cohort data flowing.
Optimization (ongoing)
Continuous testing on paywall copy, pricing, and tier structure. Most apps see 30–80% revenue lift in the first 90 days.

Why DevNest for app monetization

This is where the operator advantage matters most. Almost no agency offers genuine monetization services because almost no agency has done it. We have. Every paywall test we run on a client app has been validated against our own paywalls first. That’s not a positioning claim — it’s how we work.

02 · GROW

App Store marketing that grows downloads and keeps users coming back.

Getting live is 10% of the work. The 90% is getting discovered, reviewed well, and retaining users who convert. DevNest handles every growth lever — organic and paid.

What's included

  • App Store Optimisation (ASO) full audit
  • Keyword strategy + metadata refresh
  • Paid UA campaigns (Meta, Google, TikTok)
  • A/B tested screenshots + preview videos
  • Push notification + retention systems
  • Monthly growth reporting

  • Monthly growth reporting

Key benefits

Operator-tested playbooks

Every ASO experiment, paywall test, and acquisition campaign we run on client apps has been pre-tested in our own portfolio.

Predictable CAC.

We don't guess at acquisition costs. We benchmark, test, and optimize — and tell you when paid acquisition isn't yet the right move.

Retention before acquisition

If your retention is broken, paid ads make it worse. We fix the leaks first, then fill the funnel.

Real reporting, not dashboards full of theatre.

One monthly report, three numbers that matter, plain English on what to do next.

Our process

Audit (Week 1)
ASO audit, retention curve analysis, current acquisition channel review. Output: prioritised growth roadmap.
Foundation (Weeks 2–4)
ASO refresh, analytics setup, retention systems live (push notifications, email, in-app messaging).
Acquisition (Month 2 onwards)
Paid campaigns launched on the channels best matched to your app and target market. Tight budget control, daily monitoring.
Optimization (ongoing)
Weekly creative tests, monthly cohort reviews, quarterly strategic resets.

Why DevNest for app marketing

Most app marketing agencies have never run a profitable app. They optimize for vanity metrics — installs, impressions, click-through rates — because that’s what they can measure for clients. We optimize for the metrics that decide whether an app is a real business: paid retention, lifetime value, payback period. Because those are the metrics that decide whether our own apps survive.

03 · EARN

Monetization strategy that turns users into predictable, growing revenue.

Most apps earn a fraction of what they should. The gap is almost always monetization design — the wrong paywall, the wrong pricing, or no strategy at all. We fix that.

What's included

  • Subscription pricing strategy
  • Paywall design + A/B testing
  • Ad mediation setup (AdMob, MAX, IronSource)
  • In-app purchase architecture
  • Free-to-paid conversion audit
  • Revenue analytics + LTV modelling
Get a paywall audit →

What's included

  • Monetization strategy (subscriptions, IAP, ads, hybrid models)
  • Pricing research and benchmark analysis (by market and category)
  • Paywall design and copywriting
  • A/B testing framework for paywalls and pricing
  • Quarterly monetization reviews
  • Subscription tier and trial structure
  • In-app purchase flow design
  • Ad mediation setup (AdMob, AppLovin MAX, Unity Ads)
  • Revenue analytics (RevenueCat, Adapty)
  • Cohort revenue reporting (LTV, ARPU, payback)

FAQ

Three ways to work with us.

How much does it cost to develop a mobile app?
Most apps we build land between $45,000 and $100,000 for a full LAUNCH package, depending on scope. Apps with complex backends, multi-platform requirements, or extensive integrations sit higher. We give you a fixed quote after a one-week discovery — no time-and-materials billing, no scope-creep surprises. Quotes available in USD, GBP, EUR, or AED.
Eight to fourteen weeks from kick-off to App Store launch, depending on scope. We commit to a fixed timeline at the end of discovery and hold ourselves to it. If anything shifts, we tell you the same week.
We have offices in London, UK and Dubai, UAE, and we work with founders worldwide. Most of our work is fully remote with weekly video check-ins. Our team’s working hours overlap with North America (East Coast and Pacific), Europe, the Middle East, South Asia, and Australia — we’ll structure your project around your time zone, not ours.
Yes — by default, before any discovery work begins. Your idea is safe with us. We can sign mutual NDAs governed by US, UK, UAE, or your local jurisdiction’s law.
You do. Full source code, design files, and all intellectual property transfer to you on final invoice. We don’t retain rights, licenses, or revenue share unless we’ve explicitly structured a Studio Partnership with revenue-share terms.
Selectively — for one to two partnerships per year where we have high conviction about the founder and the market. The structure is reduced cash fee plus revenue share or small equity stake. If you’d like to discuss, mention it on your discovery call.
Yes. We work with existing apps in two ways: full rebuilds (when the codebase is beyond saving) or growth-and-monetization engagements where we leave the app alone but rebuild the ASO, acquisition, and revenue stack. The discovery call will tell us which one fits.
Yes — and we’d recommend planning for it from day one rather than retrofitting later. Multi-market launches require thinking about App Store metadata localization, pricing tier strategy, ASO keywords per language, and compliance with local data protection laws (GDPR, CCPA, UAE PDPL, etc.). We’ve launched apps in [FILL IN] languages across [FILL IN] markets.
