Android App Development — MAGNITUDE STUDIO, LOS ANGELES

Android App Development in Los Angeles

Android is not one platform — it is thousands of devices, dozens of OS versions, and every manufacturer’s quirks. We build native Kotlin apps that behave the same on all of them. Designed and coded by one team, from first screen to Google Play.

Native Android, built for real devices

Most Android problems are not code problems — they are device problems. An app that runs clean on a flagship can stutter on a mid-range phone and crash on a three-year-old OS. We build in Kotlin with Jetpack Compose and test against the devices your users actually own. That discipline runs through everything we ship — EVNTBL, FREQNCY, DRIVIFY, and PRELLEX were all designed and coded in-house to one standard: they work where their users are. The same approach behind our full app development practice, tuned for Android.

Native Kotlin, first choice

Kotlin and Jetpack Compose talk to the platform directly — no bridge layer, no waiting for a framework to catch up with the newest Android APIs.

Fragmentation is the job

Screen sizes, OS versions, manufacturer skins — we treat the spread of Android hardware as a design constraint from day one, not a bug list at the end.

Architecture that outlives v1

MVVM and clean architecture keep the codebase modular and testable, so adding features later doesn’t mean untangling the first release.

How we build for Android

Scope the product

We define what the app does, who it serves, and the device floor — minimum OS version, screen range, and the hardware features it depends on — before anything gets designed.

Design for Android

Screens built on Material Design 3, laid out to adapt from compact phones to tablets. You review real flows, not mood boards.

Build in Kotlin

Native Kotlin with Jetpack Compose, structured on MVVM and clean architecture. Camera, GPS, notifications, and biometrics are wired to Android APIs directly, not through plugins.

Test across the landscape

Every release runs against a matrix of screen sizes, OS versions, and manufacturers, with crash reporting watching for whatever the matrix misses.

Ship through Google Play

We handle the Play Console listing, data-safety forms, and the review process, then hand over every account and credential. Launch is the start, not the exit.

What an Android build includes

Native Kotlin Development

The full app written in Kotlin with Jetpack Compose — fast, current with the platform, and never one framework release behind it.

Device Compatibility

Layouts, performance budgets, and testing tuned to the real spread of Android hardware — compact screens, tablets, older OS versions, manufacturer skins.

Google Play Submission

Store listing, content ratings, data-safety declarations, and review handling — we take the app through Play compliance so approval isn’t a guessing game.

Native Feature Integration

Camera, GPS, push notifications, and biometric login built on Android APIs directly, so they behave the way users expect on their own device.

Scalable Architecture

MVVM and clean architecture from the first commit — separated layers, testable logic, and a codebase that grows by addition instead of rewrite.

Security

Encrypted storage, safe credential handling, and hardened API calls — built to meet Play policy and protect user data from the first release.

The Android stack

No fixed toolkit. We pick what fits the product — this is what Android work usually draws from.

Four products. All live.

Everything we’ve shipped is live right now, designed and coded entirely in-house. EVNTBL runs a marketplace connecting event hosts and guests; DRIVIFY books mobile auto services to your door — the app, the provider marketplace, and the backend. FREQNCY and PRELLEX round out the four: an AI-powered artist-management platform and an AI co-pilot for solo attorneys.

Bring the idea. Leave with the build plan.

Android questions, straight answers

Our existing Android app has performance and compatibility problems. Can you take it over?

Usually, yes. We start with an audit — profiling, crash data, a pass through the architecture — then tell you honestly whether the codebase is worth fixing or faster to rebuild. Either way, you get the plan in writing before any work starts.

How long does Android app development take?

It depends on scope. An MVP moves fastest; a full marketplace with a backend takes longer. We lock a written timeline at the consultation, so the schedule is a commitment, not an estimate that drifts.

How do you handle device fragmentation?

By planning for it instead of reacting to it. We set a minimum OS version at scoping, design layouts that adapt across screen sizes, and test each release on a matrix of devices and manufacturers. Crash reporting covers whatever the matrix misses in the wild.

Native Kotlin or cross-platform — which should I pick?

If Android is your main platform, or the app leans on camera, GPS, or biometrics, native Kotlin gives you the best performance and the fewest surprises. If you need both platforms from one codebase, a cross-platform build can be the right call. We build both, and we’ll tell you which fits at the consultation.

What does an Android app cost?

A flat project fee, agreed upfront and scoped to the product — no hourly meters, no surprise invoices. The number depends on what we’re building, which is why the quote comes after the consultation, not before it.

Put your product on Android, properly

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

Bring the idea — or the app that is not working. We scope it, quote a flat fee, and put the timeline in writing. Then one team designs and codes the whole thing.
