What we build

A complete app, ready to sell

From the first screen to the App Store listing, we deliver everything an app needs to be useful, profitable and discoverable — not just code.

Native SwiftUI apps

Modern Swift built for iPhone and iPad: smooth, lightweight and true to Apple's conventions. No web wrapper, no compromise on the experience.

Subscriptions & StoreKit

Subscriptions, free trials, in-app purchases: a clear paywall, well-built offers and recurring revenue collected through Apple.

iCloud sync

Data available on iPhone, iPad and Mac, synced through iCloud, usable offline and private by default.

Widgets & notifications

Home and Lock Screen widgets, helpful reminders, shortcuts: your app stays present without even being opened.

Localization

Interface and App Store listing translated — up to 44 languages on our own apps — to sell far beyond your home market.

ASO — App Store optimization

Name, subtitle, keywords, description: the App Store SEO that lifts your app in search results.

Screenshots & visuals

Icon, marketing screenshots, promotional text: a storefront that makes people tap “Get”, adapted for every language.

Publishing & App Review

Certificates, TestFlight, privacy details, submission and back-and-forth with Apple's App Review: we handle it all until you're live.

Process

From idea to App Store, in five steps

A clear framework, regular test builds on your own iPhone, and one person to talk to from start to finish.

  1. 01

    Idea

    Scoping call: audience, core feature, business model. We check demand on the App Store before writing a single line of code.

  2. 02

    Design

    User flows, screens and visual identity: a native, clean and readable iOS design, signed off with you before development.

  3. 03

    Development

    SwiftUI, StoreKit, iCloud, widgets. Regular TestFlight builds so you can try the app on your own iPhone.

  4. 04

    Launch

    App Store listing, screenshots, privacy, submission: we see Apple's review through to approval.

  5. 05

    ASO & growth

    Keywords, localization, ratings, acquisition campaigns: the app keeps climbing long after launch.

Why Adsflow

A studio that ships its own apps

Most agencies hand over an app and move on to the next project. We publish and run our own apps: every week we deal with the same review rules, the same ASO and subscription challenges you will face.

  • A verifiable portfolio: 34 apps live, open to anyone on the App Store at any time.
  • Marketing in our DNA: a Google Ads & Meta Ads agency knows how to bring users in, not just how to write code.
  • Direct access to the experts, with no salesperson between you and the people building your app.
  • Your app, your account: published under your own Apple Developer account, so you stay the owner.
FAQ

iOS app development: your questions

Q.01How much does it cost to build an iOS app?

The budget depends on scope: number of screens, subscriptions, iCloud sync, a possible back office. We almost always recommend a focused first version built around the feature that makes the app valuable, then data-driven improvements. You get a precise quote after a free, no-obligation scoping call.

Q.02How long does it take to get an app on the App Store?

A well-scoped first version takes weeks, not months; the exact schedule is set during the scoping call. Apple's review then usually takes a few hours to a few days. Because we ship our own apps regularly, we anticipate the usual rejection triggers: privacy, payments and metadata.

Q.03Who owns the app?

You do. The app is published on your own Apple Developer account, under your name. If you don't have an account yet, we walk you through creating one.

Q.04Do you also build Android apps?

We specialize in the Apple ecosystem: iPhone, iPad and Mac, in native Swift and SwiftUI. That focus is what lets us deliver a level of app quality and App Store know-how that is hard to find. If Android is essential to your project, let's discuss it on the scoping call and pick the right approach.

Q.05Can you also help market the app?

Yes — it's actually where we come from. We handle ASO (keywords, screenshots, localized listings), then paid acquisition with our Meta Ads and Google Ads specialists. An app without users is just a project, so we plan for growth from day one.
