Choosing
Should you build a cross-platform app, a native app or a web app?
A cross-platform app suits products built around accounts, forms, bookings, maps or content. We usually use React Native, sharing a codebase across iOS and Android and adding native modules when a feature needs them. That gives you both platforms without maintaining a separate codebase for each. Flutter is another cross-platform option; it uses Dart and draws its own interface, which suits heavily branded screens when your team is comfortable working in Dart.
Native development fits deeper device features, heavy graphics or complex background work. It uses Swift for iPhone and Kotlin for Android, so you have separate codebases to build and maintain. Choose this route when those device capabilities are central to the product, and account for the extra maintenance in your plans.
A progressive web app is worth considering for a staff tool. It skips store review, though it will not appear in the stores unless packaged for them. On iPhone, it can ask to send notifications only after someone adds it to the Home Screen. Start with where people need to use the product and which device features the work requires.
Local
What Ontario businesses need from an app
Service industries are a major part of Ontario’s economy. For a shop or restaurant serving repeat customers, an app can put reordering, loyalty and saved payment details close to hand. The checkout needs to be quick, while notifications need to arrive at useful moments so customers have a reason to keep them switched on.
Ontario International Airport is a freight hub, and freight operations with delivery or inspection teams need a different set of screens. Staff need to capture forms, photos, signatures and job locations away from the office. Offline working is part of the scope: the app needs to hold that information and sync it when a signal returns.
Rules
What a US mobile app project has to handle
State and local government mobile apps are subject to a rule requiring WCAG 2.1 Level AA. For a government project, we design the screens against that standard and include accessibility checks in the build, so the requirement is addressed in the product work.
Account creation also affects the release. Apple requires an in-app way to start account deletion. Google Play requires an in-app deletion path for the account and associated data, plus a web link for deletion requests. We include those paths in the account flow and the web link in the release work.
How it runs
How a mobile app project runs with us
We work remotely from India using video calls, WhatsApp and shared project boards. India time is 13h30m ahead of Pacific time in winter and 1 hour less ahead during daylight saving time. The shared board keeps decisions and feedback available across that difference.
- 01
Discover
We learn about your business, audience and goals. You help decide what belongs in the agreed scope.
- 02
Design
Put the clickable prototype in front of a few customers or staff. Their feedback helps us change screens before they are built.
- 03
Build and test
You receive test builds on your phone through TestFlight or Google Play testing tracks, so your feedback comes from using the app.
- 04
Store release
We handle the listings, submission and review under your developer accounts. You retain access to those accounts.
Checklist
What to have ready before we talk
A few decisions and materials will make the first conversation more useful.
- List the tasks people must complete in the first release, in the order they will do them.
- Start registering Apple and Google developer accounts in your company’s name; organisation verification needs a D-U-N-S number.
- Prepare a privacy policy that matches the data the app collects; Apple requires a link inside the app and in its listing.
- Check the testing requirement if you plan to use a new personal Google Play account: a closed test needs at least 12 opted-in testers for at least 14 days.
- Identify what people can do before signing up. Apple asks apps without significant account features to allow use without a login.
- Identify what the app adds beyond your website. A site wrapped in an app shell risks store rejection.
Cost & time
What affects the cost and timeline
The scope of the screens, connections and testing determines the work involved.
User roles
Customers, drivers and staff each need their own screens and permissions, even with a shared backend.
Live features
Tracking, chat and presence need persistent connections and more backend work than screens that load data on request.
Integrations
Payments, maps, booking systems and hardware each need setup, testing and handling for failures.
Interface requirements
Custom animation, extra languages, right-to-left scripts and tablet layouts add design and testing across screens.
Questions
Asked by businesses in Ontario
Page updated 5 November 2026
How much does it cost to develop an app?
There is no fixed price. Notification rules and settings, analytics and crash reporting, and moderation for user-generated content each add work to the scope. For example, a content app needs reporting and blocking features as well as a way to filter objectionable material. Agreeing the scope gives you a basis for a quote.
How do I choose an app development company?
Ask who will hold the code and account access after launch. With us, you own your domain, content and code, with no lock-in. Keep developer accounts, signing access and code repositories in your business’s name too; accounts held by an agency or freelancer can make a later move difficult.
What is included behind the app screens?
The work includes more than the app on a phone. A backend holds accounts and data, while an admin panel gives staff a place to edit content, look up customers, issue refunds and block abusive accounts. In-app purchases and subscriptions also need to be set up for both stores when they are part of the product.
Can the app use the same accounts as my website?
Yes. We build a shared backend that serves your app, website and admin tools, keeping customer accounts and data in one place. This suits a business whose customers already use its web platform frequently and need an app that works with the same underlying service.
What happens after the app launches?
Launch is followed by ongoing support, including bug fixes, updates for new iOS and Android versions, and new features. Plan regular maintenance releases: Google Play requires apps and updates to target a recent Android API level. After release, look at returning users, drop-off in the main task and the crash-free rate.
