Mobile and web apps built to launch, scale, and last
We help US startups, growing businesses, and enterprises plan, design, build, and launch iOS, Android, and web apps. You see a working build every two weeks, you own every line of code, and you get a written estimate before development begins.
A 30-minute call about your idea, timeline, and budget. No obligation.

See every serviceHow we keep app projects on track
Most app projects fail on unclear scope, hidden progress, and surprise costs. Our process is built to remove all three.
Clients get direct access to the project tools we use, such as Jira and Slack, so feedback and progress are visible in real time.
- A written estimate before you commit. Discovery ends with a scope, milestone plan, and price.
- You own the code and the accounts. Repositories, store listings, and cloud accounts are registered to your company.
- Working builds, not status reports. Every sprint ends with an app you can install and test.
- Security checked against public standards. Builds are reviewed against OWASP MASVS before release.
Built for regulated industries
Healthcare and finance apps need compliance planned into the architecture, not bolted on before launch.
Healthcare app development
Telehealth, patient portals, and remote monitoring with HIPAA safeguards and FHIR-based EHR integration.
Learn moreFinTech app development
Banking, payments, and lending apps with PCI DSS-aware architecture and strong mobile security.

Choosing the right technology
There’s no single best stack. The right choice depends on your users, budget, timeline, and the device features you need.
| Approach | Best fit when | Trade-off |
|---|---|---|
| Native iOS (Swift, SwiftUI) | Your users are mostly on iPhone, or you need deep Apple features like HealthKit, Apple Pay, or widgets. | A separate codebase is needed for Android. |
| Native Android (Kotlin, Jetpack Compose) | You serve a broad device market or need tight hardware and background-task control. | A separate codebase is needed for iOS. |
| Flutter (Dart) | You want one codebase for iOS and Android with a highly custom, consistent UI. | Some platform features need native bridging code. |
| React Native (TypeScript) | Your team already works in React and wants to share logic with a web app. | Performance-heavy screens may need native modules. |
| Web app (React, Next.js) | Users work mainly on desktop, or you need instant access without an app store install. | Limited access to some device hardware and offline features. |
How a project runs, start to finish
Each stage has a clear output, so you always know what you’re paying for and what comes next.
Discovery
We map users, goals, risks, and must-have features, then agree on a written scope, milestones, and estimate before design starts.
UX and UI design
Wireframes and a clickable prototype let you test the flow with real users before a line of production code is written.
Build in sprints
Two-week sprints end with a working build you can install on your own phone, plus a short demo and a list of what’s next.
Testing and QA
Automated tests, device testing, accessibility checks, and security review run throughout the build, not just at the end.
Launch
We prepare store listings, handle App Store and Google Play submission, and set up analytics and crash reporting.
Support and growth
After release we monitor stability, ship OS updates, and plan the next features based on real usage data.
Portfolio and case studies
Since 2013 our team has delivered projects across healthcare, FinTech, retail, energy, education, and enterprise SaaS. Recent project types include:
Telemedicine app
A HIPAA-aware telehealth app for a healthcare provider looking to modernize patient care.
Dental analytics platform
Data analysis and reporting for dental practice management data, built for a medical billing company.
iOS and Android app
A mobile app that automated client workflows for a study abroad consultancy.
Detailed case studies with client-approved results are being prepared.
What affects app development cost
Two apps with the same number of screens can differ in price several times over. These factors decide where yours lands.
Typical range: from about $40,000 for a single-platform MVP to $250,000+ for an enterprise-grade cross-platform app with backend integrations. Your written estimate follows discovery.
- Scope and complexity. Number of user roles, screens, and business rules.
- Platforms. iOS only, Android only, both natively, or one cross-platform codebase.
- Integrations. Payments, CRMs, EHRs, ERPs, maps, and third-party APIs.
- Backend and data. Real-time sync, offline mode, and admin dashboards.
- Compliance. HIPAA, PCI DSS, SOC 2 expectations, and accessibility requirements.
- Post-launch support. OS updates, monitoring, and ongoing feature work.
Ways to work with us
| Model | How it works | Good for |
|---|---|---|
| Fixed scope | One price for a defined scope and set of milestones, agreed after discovery. | MVPs and well-defined projects. |
| Dedicated team | A full team of designers, developers, and QA working only on your product, billed monthly. | Long-running products with an evolving roadmap. |
| Time and materials | You pay for hours worked, with weekly reporting and the freedom to change priorities. | Projects where requirements will shift. |
Frequently asked questions
How much does it cost to build an app?
It depends mainly on scope, platforms, integrations, and compliance needs. After a discovery call we can give a rough range, and after the discovery phase [confirm paid or free] you receive a fixed written estimate.
How long does app development take?
Timelines depend on scope. Discovery and design come first, followed by development in two-week sprints. You get a milestone schedule with your estimate so there are no open-ended timelines.
Should I build for iOS or Android first?
Look at where your target users are and what device features you need. If you need both from launch, a cross-platform framework like Flutter or React Native is often the most cost-effective option.
Will I own the source code?
Yes. The code is stored in a repository your company controls, and ownership transfers to you under the contract terms.
How do you keep apps secure?
We threat-model during discovery, encrypt data in transit and at rest, require code review on every change, and check mobile builds against OWASP MASVS before release.
What happens after the app launches?
We offer ongoing maintenance that covers OS updates, bug fixes, monitoring, and new features, so the app keeps working as iOS and Android change.
