Web and app development
CoreData builds custom web applications and internal business apps for Calgary companies: tools your team logs into to get real work done, connected to the systems you already run, and documented so they stay supportable. Building software in Calgary since 2000.
What we build
Custom app development covers a lot of ground. In practice, the work that pays for itself falls into a handful of shapes.
The tool that replaces a shared spreadsheet nobody trusts any more. Job tracking, scheduling, inspections, approvals, quoting, compliance records. Built around your process rather than forcing your process into someone else's product.
Give clients, contractors or field crews a place to submit, track and retrieve their own information, with permissions that hold and an audit trail that stands up later. Usually removes a large volume of email and phone chasing.
Structured capture at the point where the work happens, designed for a phone in a truck and an unreliable signal. Validation at entry means the data is usable when it arrives instead of being cleaned up afterwards.
Pull numbers from the systems that hold them and present them the way the business actually reviews them, rather than exporting to a spreadsheet each month and reconciling by hand.
Applications that exist mainly to make other systems agree with each other. Often the highest-return work, because it removes manual re-entry rather than speeding it up.
Native or hybrid mobile app development when you genuinely need offline capability, camera or sensor access, or field use. Where you do not, a responsive web application is cheaper to build and far cheaper to keep running.
Choosing an approach
This is the question most custom app development conversations in Calgary start with, and the answer usually turns on where the work happens rather than on preference.
| Consideration | Web application | Mobile app |
|---|---|---|
| Where the work happens | Anywhere with a browser, including desks, tablets and phones | In the field, in a vehicle, or somewhere with no reliable signal |
| Updates | Instant for everyone, no install step | App store review, and users who never update |
| Device features | Camera and location work, deeper hardware access does not | Full access to camera, sensors, offline storage and background sync |
| Cost to build and keep running | One codebase, one deployment | Higher, and multiplied if you need both iOS and Android |
| Best fit | Most internal business tools, portals, dashboards and admin systems | Field capture, inspections and anything used away from connectivity |
The honest default is a responsive web application, with a mobile app added only where the field case demands it. A firm that only builds mobile apps will not tell you that.
Why it lasts
The applications that fail are rarely the ones that were built badly. They are the ones nobody could change afterwards, because the person who built them left and took the reasoning with them.
The proof is in the case studies: systems still running years later, doing work that used to consume thousands of engineering hours.
Common questions
A website presents information. A web application does work: it holds data, enforces business rules, manages permissions and produces an outcome. If your team logs in and gets something done, that is an application, and it needs to be built and supported accordingly.
Most internal business tools should be web applications: they work on any device, need no app store approval and update instantly for everyone. A mobile app earns its place when you need offline capability, camera or sensor access, or field use where connectivity is unreliable.
Yes, and that is usually where the value is. Most operational value sits between systems rather than inside any one of them. We integrate with legacy databases, accounting and ERP platforms, field tools, sensors and vendor APIs.
You own the source, the schema and the documentation. CoreData can host and maintain it, your internal team can take it on with a documented handover, or the same team can run the surrounding infrastructure under a managed IT agreement.
Design for the worst connection your users actually have, not the one in the office. Responsive interfaces that work on a phone in a truck, tolerance for intermittent connectivity, and forms that do not lose work when a signal drops.
Each build is scoped and quoted individually after we understand the workflow, the systems it must talk to and the compliance requirements. The first conversation costs nothing: (403) 450-3438.
Often, yes. It starts with a review of the code, the data model and what documentation exists, and an honest answer about whether it is worth continuing or worth replacing. See prototype to production if it started as an AI-generated prototype.
Start with one workflow
Bring us the process. We will tell you honestly whether it needs a custom application, an integration, an automation, or nothing at all.
