Custom Mobile App Development — MAGNITUDE STUDIO, LOS ANGELES

Custom Mobile App Development for Workflows No Template Fits

Off-the-shelf software makes your business fit the tool. We do the opposite: a mobile product designed and coded around your actual workflow — every screen, every endpoint, built by one team in-house. When you’ve outgrown templates and no-code platforms, this is the next step.

When custom is the right call

Templates and no-code platforms are fine until your process stops fitting their boxes. At that point most businesses start bending the workflow around the software. We build the other way — the same front-to-back approach behind every product we’ve shipped: the software starts from how your team operates, and the code follows. DRIVIFY sends auto services to a customer’s door; PRELLEX runs records, billing, and case management for solo attorneys — neither workflow lives in any template. And if your problem does fit an existing tool, we’ll tell you at the first call.

Your workflow, not a template’s

Every screen and every data model starts from how your business runs. Nothing generic to fight against, nothing you pay for and never use.

A backend built to match

Custom apps need custom plumbing. We build the APIs, database, and admin tools alongside the app, so the whole system speaks one language.

Straight answers on scope

If an off-the-shelf product covers what you need, we’ll say so — before you spend anything. Custom is a tool, not a default.

How a custom build runs

Workflow deep-dive

We map how your business actually operates — who does what, where the friction sits, which steps the software has to carry. This is also where we tell you if custom is overkill.

Scope and fee

We define the product, cut what doesn’t earn its place, and agree on a flat project fee upfront. A written timeline is locked at the consultation.

Design

Every screen designed around the flows from step one. You see and react to the real product before any production code exists.

Build

App and backend developed together by the same team — mobile clients, APIs, database, admin tools. You get working builds to test as we go, not a reveal at the end.

Launch and handover

We ship, watch the first weeks in production, and hand over the code, accounts, and infrastructure. The product is yours.

What a custom build includes

Workflow Mapping

We document how the work actually flows before anything gets designed — roles, handoffs, edge cases. The map becomes the product spec.

Product Design

Every screen designed for your process, not adapted from a kit. You review the real flows before engineering starts.

Mobile Engineering

Native or cross-platform, chosen for the product — not for our convenience. Written so the team after us can maintain it.

Custom Backend

APIs, database, and admin tools built alongside the app. The plumbing matches the product because the same team writes both.

System Integrations

Payments, calendars, messaging, the software you already run — wired in so your team works in one place instead of five.

Full Handover

Source code, accounts, and infrastructure transferred to you at launch, with documentation. No dependency on us by design.

Tools we build with

There’s no house stack forced onto every project. We pick tools that fit the product — and that another team could pick up in five years.

Mobile

Swift & SwiftUI
Kotlin & Jetpack Compose
React Native
Expo
TypeScript

Backend & data

Node.js

Monitoring & alerting

Custom products we’ve shipped

Four custom products shipped, all live: EVNTBL, FREQNCY, DRIVIFY, and PRELLEX. DRIVIFY books auto services to a customer’s door — the app, the provider marketplace, and the backend, all built here. PRELLEX gives solo and small-firm attorneys an AI co-pilot for records, billing, and case management — a workflow no off-the-shelf tool carries.

Bring the idea. Leave with the build plan.

Custom mobile development, answered

How do I know I need custom development instead of a template or platform?

One test: does an existing tool cover the way you work without daily workarounds? If yes, use it — custom would be wasted money, and we’ll say so at the consultation. Custom earns its cost when the workflow is your edge, when no off-the-shelf product matches your process, or when the workarounds cost more than the build would.

How long does a custom mobile app take?

It depends on scope. An MVP that proves the core workflow moves fastest; a full marketplace with a provider side takes longer. We lock a written timeline at the consultation, so you know the schedule before work starts.

Do you build the backend too?

Yes — always. A custom app without a custom backend is half a product. We build the APIs, database, admin tools, and infrastructure alongside the app, the way we did for DRIVIFY’s provider marketplace.

Who owns the code?

You do. Full source code, accounts, and infrastructure are handed over — nothing stays locked in our systems, and nothing is rented from us.

Can you extend or replace an app another team built?

Usually, yes. We start with a code audit, then give you a straight recommendation: extend what exists, or rebuild the parts that can’t carry the product forward. Sometimes the honest answer is a rebuild — you’ll hear it with the reasoning, before any fee is set.

Build the tool your business actually needs

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

If you’re running a business through workarounds, the fix isn’t another subscription — it’s software shaped to the work. Bring us the workflow. We’ll scope it straight, quote a flat fee, and build it front to back.
