Not sure which service you need?

Most founders land here already knowing roughly what they want. The ones who do not usually have one of six questions in mind. Pick the one that sounds like you.

I have an idea, no code yet.

If you have validation work to do and a small budget, start with the 30-Day MVP. If you have a clearer scope and a slightly longer runway, MVP Development Services is the right page.

I have an existing app that is broken or stalled.

Fix Your App is the rescue category. Our rescue PM walks the repository on day one and gives you a real estimate before any work starts.

I know what I want built and I am weighing in-house against a team.

Hire an App Developer covers the engagement shapes, or Staff Augmentation if you want our engineers embedded into your team.

I need an app and I know the platform.

Mobile App Development is the entry point for most projects. If you have already decided platform-first, iOS Development and Android App Development cover the specifics.

I want AI features in my product.

Artificial Intelligence covers the three directions we work in: building faster with AI, building AI into your app, and stabilizing AI apps already in production.

I need software, not an app.

Web Development for production web apps. Custom Software Development when the system needs to be built around your actual workflow.

Mobile Apps

AppMakers USA builds native iOS, native Android, and cross-platform mobile apps. Four pages cover the mobile work.

Mobile App Development

The full build, from discovery to App Store and Play Store launch and beyond. We work in native Swift and Kotlin when the app needs platform-specific performance, and in React Native or Flutter when shipping speed and a shared codebase matter more. Most founders who land here are deciding between the two, and the page walks through that decision honestly.

iOS Development

Native Swift and SwiftUI for teams that need the full platform feel: Apple Pay, ARKit, HealthKit, and deep iPad support. Echo Journal, our own voice journaling app, lives on the App Store alongside client iOS work.

How we build for iOS →

Android App Development

Kotlin and Jetpack Compose across the full device range, including foldables, Wear OS, and Android TV where the brief calls for it. The right first platform when your audience skews international.

The Android page →

Dating App Development

Our deepest vertical. Eleven dating apps have come through the pipeline, including Flercha, Krush, and Meetby. Real-time matching, geolocation, and trust and safety are the three things this category lives or dies on.

Our dating app track record →

Web and Software

Three pages cover this work: production web applications, custom software built around your workflow, and the cloud layer underneath.

Web Development

Production web applications, not marketing sites. We build with Next.js, React, and Node. Most projects here are companion web apps to a mobile build, internal tools, or web-first products that will later need mobile.

What we ship on the web → Web appsPWAsAPIs

Custom Software Development

When off-the-shelf SaaS does not fit and the system has to be built around your actual workflow. For Chen Plumbing we put field work and payroll into one platform. For a national contractor network we built iPermit, a custom portal that pulls building permits across US cities.

Cloud App Development

The backend and infrastructure layer underneath the app. Cloud-native services on AWS and Google Cloud, designed for scale before launch, with per-call cost economics kept visible from day one.

The cloud layer, explained → AWSGoogle CloudServerless

AI and Intelligence

AI shows up in our work three ways. All three route to the same deep page.

We build faster with AI

Code generation, test scaffolding, and architectural review run through tools like Claude Code and Copilot as a normal part of our process. Your engagement gets a shorter sprint cycle, with every line still reviewed by a human engineer.

We build AI into your app

Conversational interfaces, smart search, content moderation, AI agents, and intelligent automation. Model choice, latency budget, and cost-per-call economics are part of the architecture conversation, not an afterthought.

We maintain and fix AI apps

For apps that already have AI features in production but need the integration tightened, the costs controlled, or the model swapped. We take over the existing system and stabilize it.

We run conversational AI in production ourselves: Echo Journal, our own voice journaling app on the App Store, ships with it.

All three, on the AI page →

Specialty Services

Six engagement shapes for teams that already know what they need, from a fixed-price 30-day build to embedded senior engineers.

ShiftPass started as an MVP engagement and grew into a marketplace connecting gig workers with businesses that need staff.

How we engage and price

Fixed price

The 30-Day MVP

One scope, one price, thirty days, a shippable MVP at the end. The only productized engagement we run, and the most predictable way to start.

Time and materials

Project builds

Full builds and rescues run on time and materials. Every engagement starts with a scoped estimate before any code is written, and we sign NDAs by default.

Monthly

Embedded teams

Staff augmentation bills monthly for three to twelve months. Our people work inside your stack, to your standards, with your PM or ours.

The honest answer on cost is that it depends on scope, and anyone quoting a number before scoping is guessing. Our mobile app development cost guide breaks down the real ranges by app type, and the first call gives you a straight read on where your project lands.

Each service page covers how we run the work, what to expect on cost and timeline, and named projects we shipped in that category. If you would rather talk first, the discovery call is a real conversation, and we tell you upfront if your project is not the right fit for us.
