Independent iOS app studio — We build iPhone apps people keep.

Develak is an independent iOS app studio. We design, build and launch native iPhone, iPad and Mac apps in Swift and SwiftUI for founders and companies worldwide — and we publish a catalogue of our own on the App Store.

Every icon here is a real app, designed, built and shipped by Develak.

What we do

Everything an iPhone app needs, under one roof.

From the first sketch to the App Store launch — and every update after that — one team designs, builds and grows your app.

iOS app development

Native iPhone, iPad and Mac apps in Swift and SwiftUI, built end to end: architecture, on-device data, sync, subscriptions and widgets.

  • SwiftUI and SwiftData
  • iCloud sync with CloudKit
  • StoreKit 2 subscriptions
  • Widgets and Live Activities

iOS app design

User flows, interfaces and clickable prototypes that follow Apple’s Human Interface Guidelines, so your app feels familiar from the first tap.

MVP development

A focused first version built around the one feature that matters, on the App Store early enough to learn from real users.

App Store Optimization

Keywords, titles, screenshots and store pages that help people find your app — methods we test on our own listings first.

App localization

Your app and its store page in the languages your users read, with String Catalogs, localized screenshots and right-to-left support.

App maintenance

Yearly iOS updates, crash fixes, new features and App Review follow-up for apps that are already live.

How a project runs

The same way every time: short cycles, a TestFlight build at each milestone, and no surprises.

Proof, not promises

We don’t just build apps for clients. We ship our own.

Pill reminders, lap timers, dive logs, wine cellars, Mac tools for developers: every app in our catalogue is designed, built, translated and maintained by the studio. Every technique we offer you, we have tested on them first.

In the spotlight

Pillio

The studio

Who is Develak?

Develak is an independent iOS app studio. We design, build and publish native apps for iPhone, iPad and Mac.

One studio covers the whole path: product design, Swift and SwiftUI code, App Store pages, localization and the updates that follow. We bring that craft to client projects, working remotely with founders and teams worldwide, in English and French.

Why native

Why build your app in native Swift and SwiftUI?

Because native apps feel right on iPhone. They launch fast, follow Apple’s conventions, work with VoiceOver and Dynamic Type, and get new iOS features the day they ship — no bridge, no compromise.

TodayView.swift
import SwiftUI
import SwiftData

@Model
final class Dose {
    var name: String
    var time: Date
    var taken = false

    init(name: String, time: Date) {
        self.name = name
        self.time = time
    }
}

struct TodayView: View {
    // Every dose of the day, kept in sync by SwiftData
    @Query(sort: \Dose.time) private var doses: [Dose]

    var body: some View {
        List(doses) { dose in
            Toggle(dose.name, isOn: Bindable(dose).taken)
                .sensoryFeedback(.success, trigger: dose.taken)
        }
        .navigationTitle("Today")
    }
}
A typical SwiftUI screen: a SwiftData model, a live query, a native toggle and haptic feedback — in about twenty lines.
  1. Private by design

    SwiftData keeps every record on the device, or in the user’s own iCloud account, with accurate privacy manifests.

  2. Fast and fluid

    A native list in compiled Swift: quick launches and smooth scrolling, up to 120 Hz on ProMotion displays.

  3. Accessible by default

    A native toggle: VoiceOver announces it as a switch, and Dynamic Type, Dark Mode and Reduce Motion just work.

  4. New iOS features on day one

    One line adds haptic feedback. Widgets, Live Activities and App Intents arrive the same way, as soon as Apple ships them.

FAQ

Questions founders ask us first

Short, straight answers. Anything else? Write to us at contact@develak.com.

What is Develak?

Develak is an independent iOS app studio. It designs, builds and publishes native iPhone, iPad and Mac apps in Swift and SwiftUI — for its own catalogue of 34 App Store apps and for clients worldwide.

How much does it cost to build an iPhone app?

It depends on the scope: the number of screens, the data to store and sync, subscriptions, integrations such as Apple Health, and how much design work is needed. After a first conversation, Develak sends you a written estimate broken down by milestone, so you know what each stage involves before anything starts.

How long does it take to build an iOS app?

A focused first version (MVP) usually takes a few weeks; a complete app with iCloud sync, subscriptions and widgets takes longer. Milestones are agreed before any code is written, and you can test each one on your own iPhone through TestFlight.

Why choose native Swift over Flutter or React Native?

Native Swift and SwiftUI apps start faster, feel consistent with iOS and get new Apple features — widgets, Live Activities, Apple Health, App Intents — as soon as they ship. Cross-platform tools make sense when Android is a must from day one; for an iPhone-first product, native is usually the better long-term investment.

Which platforms does Develak build for?

Apple platforms only: iPhone first, then iPad and Mac from the same Swift codebase when it makes sense. The studio also publishes Mac tools for developers, such as Xlocalize for translating Xcode String Catalogs.

Can you improve an app that is already on the App Store?

Yes. Develak maintains and improves live apps: yearly iOS updates, bug and crash fixes, new features, App Store Optimization, and localization into new languages.

Do you work with clients outside the United States?

Yes. Develak works remotely with founders and companies worldwide, in English and French, and ships apps in up to 44 languages.
