// MOBILE APP DEVELOPMENT — /mobile

Custom mobile app development by a desk that carries all four toolchains — so the recommendation isn't rigged.

Ask a Flutter shop what to build and you'll get a Flutter app. This desk writes Swift, Kotlin, React Native, and Flutter — so the mobile app development recommendation follows your case, in writing, with reasons. One senior developer in Austin, one fixed number before a line of code, and the app ships to both stores under your name, not ours.

// THE FOUR TOOLCHAINS

Every shop lists these four logos. Ask them when they'd pick each one, and the pitch goes quiet.

Here's the actual prescription logic — the same one your written quote will apply to your case, with reasons. (For calibration: one agency ranking beside this page tells buyers that Swift and Kotlin are "web technologies." That's who's educating this market.)

Custom mobile app development, one desk to both stores — a hand holding a finished app at night, and the workbench with two phones and wireframes where it was built; line illustration
NATIVE · iOSSwift

Apple's own language for its 175-region store. Prescribed when: your audience is iPhone-first, the app leans on deep device features — camera pipelines, widgets, HealthKit — or the product competes on iOS polish.

NATIVE · ANDROIDKotlin

Used by over 60% of professional Android developers, and apps written in it are 20% less likely to crash — Google's own numbers. Prescribed when: Android-only fleets, field crews on rugged devices, Play-first markets.

CROSS-PLATFORMReact Native

Meta's framework — Instagram, Discord, Bloomberg run on it, and "all mobile apps at Shopify are built using React Native." Prescribed when: both stores on one codebase, a web app that shares logic, JS talent on your side.

CROSS-PLATFORMFlutter

Google-managed, natively compiled — BMW, Toyota, and Google Pay ship on it. Prescribed when: both stores, design-heavy custom UI that must look identical everywhere, fastest path to a polished v1.

The fifth option nobody on this search will mention: you might not need a store app at all. If customers arrive through your website, an installable progressive web app does the job for less — offline, push notifications, a Home Screen icon — with no store between you and them. That sentence is in the quote when it's true, which is exactly why the rest of the quote can be trusted.

THE PWA DESK — FROM $4,900 →
// WHERE $90,780.11 GOES

The industry's average app invoice, dissected.

Clutch's directory puts the average app project at $90,780.11 and the typical timeline at about 11 months. Neither number is a scandal — it's arithmetic. GoodFirms prices a US senior Swift developer at $130–$200+ an hour; now add the rest of the pod that bills alongside them, month after month.

This desk deletes the middle column, not the craft: one senior who designs, builds, tests, and ships — in weeks, for a number that was fixed in writing before work started.

LINE 1

The pod. A project manager, two developers, a designer, and QA — five people on the clock for those ~11 months, whether this week needed five people or one.

LINE 2

The toll before the quote. Some firms publish it plainly: paid "discovery" at $2,500–$10,000 before you're told a build price. Here the discovery is the quote — free, written, 24 hours.

LINE 3

The meter. "Time & materials" means the risk of every re-explained requirement lands on your invoice. A fixed number means misreads are the builder's scrap to eat — which is why so few builders print one.

LINE 4

The translation layer. Your idea passes from account manager to PM to a rotating bench. Every hop bills, and every hop loses signal. Here the person who heard the idea is the person who ships it.

// THE STORE TAX, PRINTED

What Apple and Google actually charge — the part agencies mention after the handshake.

Zero of the seven competitors we tore down print any of this. It's all from the platforms' own pages, and none of it is scary — it just belongs in the plan before you commit, not after.

ITEM IN THE PLATFORMS' OWN WORDS COST
Apple Developer ProgramYour listing in "175 regions" — registered in your name here, not an agency's$99/yr
App Store commission30% standard; 15% under $1M/year via Apple's Small Business Program — only on digital goods sold in-app15–30%
App review"On average, 90% of submissions are reviewed in less than 24 hours" — Apple~24h
Google Play registrationOne-time developer registration, your account$25 once
Google Play feesGoogle's own summary: "97% of developers distribute… at no charge," and of those who do pay, "99% are eligible for a fee of 15% or less"$0 for most

A SELLABLE APP PRODUCT IS THE SAAS DESK; PAYMENTS AND MONEY FLOWS INSIDE THE APP ARE THE FINTECH DESK; THE GO + POSTGRESQL BACKEND UNDER EVERY BUILD IS THE SAME ONE POWERING OUR BUSINESS SYSTEMS.

// VERSION HISTORY

From idea to "Ready for Sale," logged like release notes.

The competitors' reply promises — "2-minute response," "1 hour," "24 hours guaranteed" — all end in the same place: a sales call. Only one of the seven promises an actual deliverable. Here the deliverable is the promise: a written, fixed quote in 24 hours, then a build you watch land on your own phone week by week.

And because the store accounts are yours from day one, there is no hostage scenario at the end — no agency holding your listing, your keys, or your customers while an invoice gets negotiated.

// BEFORE YOU INSTALL

The questions the sales decks skip.

Answered the way the quote will be — plainly, in writing, with the platform vendors' own numbers where numbers exist.

Q-01.What does custom mobile app development actually cost here?

From $14,500 for a focused cross-platform app — one codebase, both stores, one job done completely. $25,000–$55,000 buys the bigger builds: accounts and roles, payments, offline sync, a Go backend with an admin panel. For scale: Zco's own FAQ calls $40,000 "basic," LaunchPad Lab prints $50,000–$100,000 for an MVP, Clutch's average is $90,780.11 — and some firms charge $2,500–$10,000 in "discovery" before you learn their number. Ours is free and takes 24 hours.

Q-02.Which of the four toolchains will you pick for us?

The one your case argues for, and the quote shows the reasoning: who installs the app, on what devices, which platform features it leans on, what your team can maintain. Most business apps land on React Native or Flutter — both stores, one codebase, lower price. Native Swift or Kotlin gets prescribed when the app genuinely lives off deep platform features. What never happens: a prescription that conveniently matches the only thing the shop knows how to write.

Q-03.Is cross-platform really as good as native?

For most business apps — portals, bookings, field tools, catalogs — yes, and the companies betting on it are not small: Shopify runs all its mobile apps on React Native; BMW and Toyota ship Flutter. Where native earns its premium: heavy camera and sensor work, AR, games, audio processing. If your app is in that list, the quote says so — and native for both platforms runs roughly a third to half more, priced exactly, never discovered later.

Q-04.One developer, for an app our business depends on?

Count what actually protects you: the code in your repository, the store accounts in your name, the backend in boring Go + PostgreSQL, documentation any developer can pick up — all transferred, not licensed. The pod alternative protects the agency: five roles billing ~11 months, your idea passing through an account manager to a rotating bench. One senior with all four toolchains and no translation layer is not the risky option in that comparison. And yes — an NDA comes standard if you want one, before you share a word.

Q-05.Who owns the app, the code, and the store listings?

You, from day one — and this is the question that saves businesses real grief. The Apple ($99/yr) and Google Play ($25) developer accounts get registered in your name before the first build ships; the repository, certificates, and signing keys live in your accounts; we work as invited members you can remove in one click. When an agency owns the listing, the agency owns the relationship with your customers. That arrangement is never offered here, in either direction.

Q-06.What happens after launch — updates, OS releases, the long tail?

Sixty days of fixes at $0, then a printed number nobody else will print: $390 a month flat for keeping it current — annual iOS and Android releases absorbed, store re-submissions handled, crashes monitored, small changes shipped. Cancel anytime; the handoff docs mean any developer can take over. The industry's habit is to reveal maintenance pricing after the handshake. Ours is four paragraphs above the contact form.
