One Build for iPhone and Android
Canadian phone users are split between iPhone and Android, and neither side is small. If your customers are on both, you need an app on both. Building two separate native apps means two codebases, two sets of bugs and close to double the budget.
Cross-platform development fixes that. We write your app once in Flutter or React Native, and it runs on iPhone and Android phones and tablets. You launch on both stores at the same time, and every update ships to both at once.
The App Bros Canada builds cross-platform apps for businesses and founders across the country. Our team has launched cross-platform apps like The Dandie and Hands2Paws, both live on the App Store and Google Play. For most first versions, this is the approach we recommend.
What's Included
Platform Advice
An honest call on whether cross-platform suits your app, or whether native makes more sense.

Cross-Platform Apps We've Built
Pets
Hands2Paws
Matches people with the dog breed that fits their lifestyle and home.
The Dandie connects people through the services they offer, from pet care to carpentry, and runs on both iPhone and Android. Hands2Paws matches people with dog breeds that fit their lifestyle, using a short questionnaire and a matching algorithm. Both launched on the App Store and Google Play from one codebase.
- Flutter
- React Native
- Firebase
- Swift
- Kotlin
We build in Flutter and React Native, and we still know Swift and Kotlin for the times an app needs native code for a single feature.
Flutter or React Native? How We Choose
Both are mature, widely used and backed by big tech companies. Flutter comes from Google, and React Native comes from Meta. Either one can power a fast, polished app. The right choice depends on your project:
- Flutter paints every pixel itself, so your app looks the same on every phone. It's a great fit for apps with custom visuals, animations and a strong brand look.
- React Native uses JavaScript and the phone's own interface parts. It's a good fit if you already have a React web app or web developers who'll help maintain the app later.
- Your team matters. If you plan to hire in-house developers after launch, we'll pick the framework they'll find easiest to take over.
You don't need to know any of this before we talk. We'll explain the trade-offs in plain English at your consultation.
What Cross-Platform Apps Cost
Most cross-platform projects fall into these planning ranges:
| Budget tier | Planning range (CAD) | Best for |
|---|---|---|
| Lean MVP | $21,000 – $42,000 | Core app flow, basic accounts and a limited feature set |
| Growth build | $28,000 – $71,000 | Custom design, admin tools, payments or messaging |
Planning ranges, not quotes. Your price depends on your features, backend and timeline.
What moves the price? The number of screens and user types, payments, live features like chat or GPS tracking, and how much your app needs to connect to other systems. Because you're paying for one build instead of two, cross-platform often lands near the low end of what two native apps would cost.
When Native Still Wins
Cross-platform isn't right for every app. We'll tell you to go native when:
- Your app leans hard on device hardware, like advanced camera work, Bluetooth accessories or augmented reality.
- You need the newest iPhone or Android features the day they come out.
- Your users are almost all on one platform, so a second one adds cost without adding customers.
In those cases, see our iOS app development or Android app development pages.
Web App and Admin Panel Add-Ons
Many apps need more than the phone app. You may want a web dashboard for staff, a customer web portal, or an admin panel to manage users, orders and content. Flutter can also build web apps from much of the same code, and React Native teams often share logic with a React web app. We plan these add-ons up front, so the whole system fits together.
How We Build Your App
- 1
Idea
A free, confidential consultation. We listen, ask good questions and put your idea on paper.
- 2
Design
The look and feel of every screen, shared online so you can give feedback as we go.
- 3
UX/UI
Wireframes and a clickable prototype that show exactly how every feature works.
- 4
Coding
We build and test your app, then publish it on the App Store and Google Play.
- 5
Launch & Marketing
We help you market the app and grow downloads after launch.
Launch and App Marketing
An app store listing isn't a launch plan. After your app goes live, we help you get it found: store listing copy and screenshots, launch timing and early download campaigns. Then we look at how people use the app and plan the next update.
Cross-Platform FAQs
Is Flutter cheaper than building two native apps?
Usually, yes. One codebase means one build and one set of updates for both platforms. Most clients spend noticeably less than they would on two separate native apps. We'll compare both options for your app at your consultation.
Does a cross-platform app feel native?
A well-built one does. Flutter and React Native apps can run smoothly, follow each platform's design habits and use device features like the camera, GPS and push notifications. Most users can't tell the difference.
Can you take over my existing Flutter or React Native app?
Yes. We start with a code review to see what condition the app is in. Then we give you a plan to fix, finish or grow it.
Is Flutter still a safe choice?
Yes. Google keeps building on Flutter and uses it in its own products, and thousands of companies ship apps with it. React Native is just as well established. Either one is a sound choice for a new app.
