How much does it cost to build a mobile app?

The full build cost depends on features, platforms and integrations, which is why we start with Discovery & Prototype. It ends with a technical scope, timeline and fixed quote for the build. If you go ahead, the $1,999 is credited toward the build.

What platforms do you develop mobile apps for?

We build apps for iPhone (iOS) and Android, and can also build web apps that work in a browser. We'll recommend platforms based on who your users are.

What's the difference between native and cross-platform apps?

Native apps are built separately for iOS and Android, which can suit apps needing heavy device features. Cross-platform apps share one codebase for both, which usually costs less and is faster to maintain. For most business apps, cross-platform is a strong choice.

How long does it take to develop a custom app?

It depends on the number of features, platforms and integrations. Discovery and prototyping comes first, and it ends with a build timeline alongside your fixed quote. Starting with a focused first version (an MVP) is usually the fastest way to launch.

Do you handle App Store and Google Play submissions?

Yes. We prepare your listings, screenshots and descriptions and guide the app through Apple and Google's review processes. The developer accounts are set up in your business's name so you own them.

Do you offer post-launch support?

Yes. Apps need updates for new phone software, bug fixes and new features. We offer ongoing support so your app keeps working well after launch.

Who owns the app and code?

You do. Once the project is paid, the code, designs and store listings belong to your business.

What types of businesses do you build apps for?

We work with local businesses and startups across Ontario, including booking and service apps, customer portals, loyalty apps and internal tools for teams. If you have an idea, Discovery is the best place to test whether an app is the right solution.

Mobile App Development

Native iOS & Android apps

For businesses and founders with an app idea: a clear plan, a working prototype, then an app for iOS and Android.

Problem

What mobile apps solve for your business

Relying solely on desktop portals reduces user engagement. Dedicated mobile apps keep you connected to your clients through push alerts, rapid UI speeds, and offline capabilities.

You lack a mobile interface

Your competitors engage buyers through dedicated apps. You rely on browser portals, missing out on push notifications and direct home screen access.

Your existing workflows are paper-heavy

Your field agents and staff rely on manually logged paperwork. A custom app replaces paper processes and reduces admin overhead.

Your responsive site isn't enough

Customers need faster, offline-capable mobile workflows. Native mobile apps can make transactions quicker and help bring customers back.

Native or cross-platform: choosing the right approach

Native iOS and Android

Native apps are written separately for each platform: Swift for iOS, Kotlin for Android. They get full access to device features such as the camera, GPS, Bluetooth, health data and background tasks, and they feel exactly like other apps on the phone. The trade-off is two codebases to build and maintain. Native is usually the right choice when performance or deep device access matters, or when most of your users are on one platform.

Cross-platform with React Native or Flutter

Cross-platform frameworks let one codebase run on both iOS and Android. That usually means a faster build and simpler updates, because a fix is made once and released to both stores. Most business apps, such as booking, ordering, loyalty and field-service tools, work well this way. Where a feature needs native code, we add it for that platform only.

A web app or a better mobile site

Sometimes the honest answer is that you don't need an app yet. If your customers only use it once or twice, a fast mobile website or web app may do the job for less. We'll tell you during the free app idea review. See our web design and development service.

What we connect your app to

An app is rarely on its own. It needs to talk to the systems you already run.

Payments

Payments and in-app purchases through Apple and Google, set up to follow each store's payment rules.

CRM and ERP systems

Customer records, orders and job data synced with the tools your team already uses, so nothing is entered twice.

Firebase and AWS

Logins, databases, file storage, analytics and push notifications using Google Firebase or Amazon Web Services.

REST APIs and your website

Your app can share data with your website, booking system or online store through APIs, so both stay in sync.

Maps and location

Store locators, service-area checks, live job tracking and directions using map services.

Push notifications

Appointment reminders, order updates and offers sent straight to your customers' lock screens, with opt-in handled properly.

Mobile app development in London, Ontario: what to plan for

A few things worth knowing before you build. We walk you through each one during Discovery & Prototype.

Store developer accounts. Apple and Google each charge a developer account fee. We recommend the accounts are registered in your business's name, so you always control your listings.
Store review. Apple reviews every app and update against its App Review Guidelines before release. Google Play has its own policy checks. We plan time for review in the schedule.
Privacy. Both stores require a privacy policy and a description of the data your app collects. If you're in Canada, your app also needs to follow Canadian privacy law (PIPEDA) when it handles personal information.
Version one, not everything. Launching with core features first lets you learn from real users before spending on extras.
Content and accounts. Screenshots, store descriptions, app icons and test logins all need to be ready before submission.
Ongoing updates. Apple and Google release new operating system versions every year. Apps need updates to keep working and stay in the stores.

Why build your app with a local team

We're based at 777 Apricot Dr in London, Ontario, and have worked with businesses across Southwestern Ontario and the GTA since 2019. Being local means you can meet the people building your app, and we can sit down with your staff to see how work really gets done before we design anything.

Your app doesn't have to stand alone either. The same team can build the website it connects to, set up local SEO so people find you, and run paid ads to drive downloads. Fewer handoffs means fewer gaps.

Book a free strategy call

Most projects start with App Discovery & Prototype ($1,999 + HST). A discovery workshop sets your app's goals and feature priorities, then we create a clickable prototype of the key screens you can test and show to others. It gives you a clear plan and a more accurate build estimate before you commit to development.
