One team, from idea to live product

Most app projects die between the agencies: one shop does the brand, another designs screens, a third codes the front end, a fourth builds the API — and nobody owns the outcome. We do the entire build under one roof: product strategy, UI/UX, front-end, back-end, launch, and the growth systems after. That’s how EVNTBL, FREQNCY, DRIVIFY, and PRELLEX shipped — each one designed and coded end to end by us, and each one live today.

Full-stack, in-house

Front end, back end, APIs, databases, admin tools — written by the same team that designed the product. No handoffs, no gaps.

Design-led product

Apps people actually want to use: considered UX, real interaction design, and an interface that feels like a brand — not a template.

Launch is the start

We ship it, then stay on it — the same studio that builds your website, runs your ads, and wires your automation keeps the product growing.

How we build your app

Scope the product

We map what the app must do, who it serves, and the smallest version that proves it — features, flows, and platforms, agreed in writing.

Design every screen

Wireframes to full UI: the complete product designed and clickable before heavy engineering begins, so you approve what users will actually touch.

Build front to back

Interfaces, business logic, APIs, databases, payments, accounts — the whole stack, hand-coded by the team that designed it.

Test & launch

Real-device and real-scenario testing, then a controlled launch — app-store or web release, hosting, monitoring, and analytics wired from day one.

Operate & grow

Post-launch we fix, improve, and extend — and connect the product to the marketing system that feeds it.

App development we do

Web App Development

Browser-based products — marketplaces, dashboards, SaaS tools — built on modern stacks and coded end to end.

Mobile App Development

Mobile-first products designed for the way people actually hold and use them — fast, native-feeling, and considered.

Product & UI/UX Design

Flows, wireframes, and full interface design — the product thinking that separates apps people keep from apps people delete.

MVP Builds

The smallest version that proves the idea — scoped tight, built fast, and architected so it can grow instead of being thrown away.

Back-End & APIs

The engine room: databases, APIs, authentication, and admin tools — engineered for real users, not just the demo.

Payments & Integrations

Stripe, calendars, maps, messaging, AI services — wired into the product wherever the experience needs them.

App Branding & Identity

Name, mark, type, and voice for the product itself — we branded FREQNCY before we coded it.

Launch & Ongoing Support

Deployment, monitoring, updates, and new features after launch — the build relationship doesn’t end at v1.

Four apps, shipped end to end

Not mockups — live products, each one designed and coded entirely by us.

EVNTBL

Full-stack build. Events marketplace connecting hosts and guests with taste — every screen and every endpoint, front to back.

FREQNCY

Brand & full-stack build. AI-powered artist-management platform — we created the brand and identity, then coded the entire app.

DRIVIFY

Full-stack build. Mobile auto services booked in under a minute — the app, the provider marketplace, and the backend.

PRELLEX

Full-stack build. AI co-pilot for solo and small-firm attorneys — records, billing, and case management, coded end to end.

App development questions, answered

What does it cost to build an app?

A flat project fee agreed upfront, scoped to what the product actually needs — no hourly surprises. An MVP costs a fraction of a full platform, which is why we scope the smallest version that proves the idea first.

How long does an app take to build?

It depends on scope: an MVP moves much faster than a full marketplace. We map the feature set on your consultation call and lock a written timeline before the build starts.

Do you design and code, or just one of them?

Both, end to end — product strategy, UI/UX design, front-end, back-end, and launch. Every app we’ve shipped was designed and coded entirely in-house.

Web app or mobile app — which do I need?

We build both, and we’ll tell you honestly which fits your product and budget. Many ideas launch fastest as a web app and go mobile once the model is proven.

Who owns the code?

You do. Full source code, accounts, and infrastructure are handed over — the product is yours, not rented from us.

What happens after launch?

We stay on — fixes, improvements, and new features, plus the website, ads, and automation that grow it. One studio, the whole system.

Have an app idea? Let’s scope it.

Magnitude is how scientists measure what gets felt. So do we.

Bring the idea — on the call we’ll map the features, the smallest version worth building, and what it takes to ship it.
