What you get
Mobile app development, done properly
Your app should earn its place on a customer's phone. Bytecode builds iOS and Android apps for US DTC brands and growing businesses, with practical choices around Flutter, Ionic, Swift, Kotlin, and backend architecture.
We connect apps to Shopify, custom APIs, CRMs, and internal systems. If a fast mobile website or PWA is the better move, we will say so before you fund a native app.
Cross-platform app builds
We build Flutter and Ionic apps when one shared codebase makes sense. This can help you ship consistent iOS and Android experiences without duplicating every feature.
Native iOS and Android
We use Swift or Kotlin when the product needs deeper platform behavior, better device access, or stricter performance control. The stack follows the app, not a trend.
Shopify and backend links
We connect mobile apps to Shopify, custom APIs, CRMs, and internal tools. Your product, customer, order, and account data can stay tied to the systems your team already uses.
Accounts and push
We build login, profiles, saved preferences, and push notification flows. We keep the experience useful so the app does not feel like another marketing channel.
Payments and checkout flows
We implement payment and checkout flows based on your app type, platform rules, and business model. For DTC apps, that may include Shopify-connected commerce or a custom backend flow.
Release and maintenance
We prepare builds for App Store and Google Play submission support. After launch, we can handle fixes, OS updates, feature work, and performance cleanup.
How it works
From first call to launch
01
Scope the job
We map the users, business goals, must-have features, backend needs, and whether a mobile app is the right first move.
02
Choose the stack
We recommend Flutter, Ionic, Swift, Kotlin, or a PWA based on product needs, maintenance cost, and platform requirements.
03
Build and test
We design, develop, integrate, and test the app across the devices and flows that matter to your customers.
04
Release and improve
We support store release, monitor issues, and help your team plan the next set of product improvements.

FAQ
Questions, answered
Do we need a mobile app, or is a mobile website enough?
Not every business needs an app. If customers only need to browse, buy, read content, or submit a form, a fast mobile site or PWA may be enough. We will say that before you spend on native app development.
Can you build both iOS and Android apps?
Yes. We build iOS and Android apps using Flutter, Ionic, Swift, or Kotlin. The best option depends on features, budget discipline, long-term maintenance, and how much platform-specific behavior your app needs.
Can the app connect to Shopify?
Yes. We can connect your app to Shopify for product, customer, cart, order, and account-related flows where the platform supports it. We can also connect the app to a custom backend when Shopify is only one part of the system.
Do you handle App Store and Google Play release?
Yes. We help prepare production builds, release assets, store metadata, and submission steps for App Store and Google Play. Approval decisions still sit with Apple and Google, so we plan around their rules rather than promising approval.
Can you add push notifications and accounts?
Yes. We build account systems, login flows, profile screens, saved preferences, and push notification logic. We also help define when notifications are useful so you do not train customers to ignore the app.
Can you maintain an existing mobile app?
Yes. We can review an existing iOS, Android, Flutter, or Ionic app and identify the main technical issues. Maintenance can include bug fixes, OS compatibility updates, performance work, backend changes, and new features.
