App development services — for buyers who haven’t picked a path yet
Web apps, mobile apps, PWAs, no-code — all built AI-assisted with Claude Code. We’ve shipped 60+ projects across all five paths and we’ll tell you which one fits before we quote.

App development services at NerdHeadz means five delivery paths: AI-assisted (Claude Code) builds compressing any of web, native mobile, PWA, or no-code timelines by ~3×. Typical scope: $5k–$250k+, 3–24 weeks, fixed-price after a 30-minute scoping call. We tell you which path fits before quoting. 60+ shipped since 2022, 90% retention.
The five kinds of apps we build
Four output shapes plus the AI-assisted methodology that compresses any of them. Side-by-side trade-off. AI-assisted (Claude Code) is how we ship most modern builds.

Not sure which kind of app you need?
Four questions. No salesy filler — the same decision tree we walk every prospect through on the scoping call.
- Q1
Does your product need to be in the App Store or Play Store?
YES→ Q2NO→ Q3 - Q2
Does it need deep device APIs (AR, on-device ML, HealthKit, CarPlay)?
YES📱 Native Swift/KotlinNO📱 Native cross-platform - Q3
Will users access it on phones primarily?
YES→ Q4NO🖥️ Web app - Q4
Do you sell digital goods or subscriptions?

The numbers behind the choice
Industry data — not our opinions. Sourced from public research published 2024–2026.
Typical time to launch
Day-30 retention by category
“Cross-platform development reduces costs by 20–40% compared to building separate native apps.”
What we build at each path

🖥️ Web apps
SaaS platforms, marketplaces, internal tools, B2B portals — anything that lives at a URL and serves users with logins.
- SaaS products with multi-tenant requirements
- Operational dashboards with live data and exports
- Two-sided marketplaces with payments and reviews

📱 Native mobile
iOS and Android apps in the App Store and Google Play — consumer products, daily-use apps, products that need camera, GPS, biometric, or AR.
- Consumer apps shipped to both stores
- B2B field-service companion apps
- Subscription apps with native paywall flows

🌐 PWA
Web apps that install to the home screen, work offline, send notifications, and skip the app stores entirely. The right answer for digital goods, B2B tools, and founders who can’t afford Apple’s 30% IAP cut.
- Subscription products avoiding the Apple cut
- B2B tools where customers know your URL
- Iteration-heavy products needing weekly updates

⚡ No-code apps
MVPs shipped in 3–6 weeks on Bubble or FlutterFlow. The right answer when you’ll maintain the app yourself, when speed beats scale, or when the product is still finding fit.
- MVPs validating product-market fit
- Internal tools used by under 50 people
- Founder-maintained apps where dev hiring isn’t justified yet

The stack we build on
We pick per project. These are the tools we reach for most, organized by path. Stack philosophy: custom software development.

Founders who hired NerdHeadz to build real apps — web, mobile, marketplace, MVP.
This system has been a dream of mine for almost a year. I have tried to build it myself and finally came to the conclusion I needed help. The NerdHeadz team has built me exactly what I was dreaming about and more! Working with them has been an absolute pleasure. I can't thank them enough.
Why teams pick NerdHeadz for app development
Path-agnostic, on purpose.
We use all five paths — AI-assisted, web, native, PWA, no-code. Most agencies sell one and pretend the others don’t exist.
Honest scoping, before money changes hands.
The Path Decision step (Step 2 of our process) is paid only if you proceed with the build. If we recommend you skip a custom app entirely and use Retool or Webflow, we say so.
AI-assisted velocity.
Claude Code accelerates the mechanical layer — boilerplate, scaffolding, type refinement. Engineers own architecture and judgment calls. About 3× faster than traditional builds at the same quality bar.
You own everything.
Code, credentials, infrastructure. No black-box hosting. Any engineer can pick up the project after handoff. Even on no-code builds, we hand over the account, not a license to it.

Frequently asked questions
Web apps live in the browser and serve users with logins — SaaS platforms, dashboards, marketplaces. Native mobile apps are in the App Store / Play Store and have access to device APIs (camera, GPS, biometric). PWAs are web apps that install to the home screen, work offline, and skip the app stores — they’re the right answer when Apple’s 30% IAP cut would break your unit economics. No-code apps are built on platforms like Bubble or FlutterFlow — the fastest path to an MVP, but you trade ownership of the underlying code.
The decision tree on this page answers it in four questions: does it need to be in the App Store, does it need device APIs, will users be on phones primarily, and do you sell digital goods. If you’d rather just talk it through, a 30-minute scoping call ends with a concrete recommendation — even if that recommendation is "don’t build a custom app at all."
Depends on path and scope. No-code apps: $5k–$25k. PWAs: $15k–$75k. Cross-platform native: $25k–$120k. Fully native iOS+Android with separate codebases: $50k–$250k+. After the scope call you get a fixed-price quote tied to a concrete scope document.
No-code MVPs: 3–6 weeks. PWAs: 4–10 weeks. Cross-platform native: 8–16 weeks plus app-store review. Fully native (parallel teams): 12–20 weeks plus review. We ship in 2-week sprints — you see working software at the end of every sprint.
Yes. Most projects include the backend (Node.js or Python), the database (PostgreSQL or MongoDB), API design, auth, push notifications, and cloud deployment. We don’t hand off half an app.
Yes — full submission process for native apps. App Store Connect setup, screenshots, metadata, privacy nutrition labels, App Tracking Transparency, Google Play data safety. First submissions are rarely approved simultaneously on both stores; we budget a rejection-and-resubmit cycle into every timeline.
You do. Repository, credentials, infrastructure. On no-code projects, you own the workspace (Bubble, FlutterFlow account, etc.) — we transfer ownership at handoff. We don’t keep black-box copies.
Yes — that’s one of our most common engagement shapes. We rebuild the app on Next.js + Node.js or React Native while preserving features, SEO, and user data. See our no-code migration service.
Claude Code (Anthropic’s coding agent) and Cursor run alongside our engineers. The mechanical layer — boilerplate, scaffolding, test harness, type refinement — gets accelerated ~3×. Engineers own architecture, data modeling, and the platform-specific judgment calls. AI-assisted is a methodology that wraps the four output paths (web, native, PWA, no-code) — not a separate kind of app.
Both. About 60% of shipped projects are funded startups (seed to Series B), the rest are operators inside larger companies who need a specific app shipped quickly. The path-decision conversation works the same way — we tell you which path fits and what fixed-price quote follows.
Yes. Most often this is a code audit + remediation pass + a maintenance retainer. We document what we find, prioritize the bug/perf/security backlog with you, then either ship the fix-pack or hand it off to your team. Common starting point: 1-week paid technical audit ($3k–$8k depending on scope) — credited toward the build if you proceed.
Yes. We typically retain ~60% of clients on a post-launch retainer covering bug fixes, monitoring, feature increments, and SLA-backed response. Retainers start at $4k/month for one app. See the maintenance and support service for details.
