Our App Development Services

Internet of things

Internet of Things

Sensors, wifi, Bluetooth, wearable devices – we know all the ways you can make your Internet of Things (IoT) product idea come to life and connect to any device.

Over the last 5 years, we’ve accumulated experience developing innovative and engaging mobile applications compatible with Internet of Things (IoT) technologies, and we’re ready to accommodate your mobile app development project. Let us share our expertise and experience with you, and let’s bring your connected objects and ideas to life.

Our talented in-house app developers in Montreal and Toronto are experts in IoT app development and have experience building quality digital products. With so many OEMs (original equipment manufacturers) adapting and creating IoT-friendly devices, the opportunities for mobile app developers to innovate are endless.

Apple Watch, Bluetooth, RFID, sensors, Raspberri Pi, beacons – you name it, we know how to handle all the technology available to bring your idea to life.


Augmented Reality

From games to simulators, Augmented Reality has opened several doors when it comes to mobile app development.

After the Pokémon Go frenzy introduced users to this technology, countless companies have been leveraging it as a way of differentiating themselves from the competition, engaging users and creating extremely interactive brand experiences through mobile apps.

Integrating AR into your digital product is a great way to create real-life experiences, simulate training or product experiences, or add virtual adventures to your marketing stunt. Take advantage of our AR app developers in Montreal or Toronto to enhance your product experience by adding an AR/VR engagement element to it through a mobile app.



As a mobile app development company, we love working with Beacon. Beacon app development is poised to transform how retailers, event organizers, transit systems, enterprises, and educational institutions communicate with people indoors. We believe the opportunities for this local, real-time targeting technology are endless.

Retailers are the first prominent market for beacons, from in-store coupons delivered via beacons to customer phones to collecting data to run personalized loyalty programs and ad campaigns. They can also trigger an automatic payment when a person leaves a specific location so that payment becomes effortless.

Beacons are commonly used at music and sporting venues to communicate information, point people to complementary content, promote sales and are widely used in airports, train stations, urban transit hubs to alert travellers of delays, changes, and weather conditions.

Web Apps

Web App

We can create web applications or extend your mobile digital product to the web, allowing even more users to have an unparalleled experience and increase your potential customer reach. Our team of experienced mobile app developers and designers will design, develop, and deliver user-friendly and fully functional web apps and websites for any industry.

We’re experienced in building cross-platform mobile apps and web applications. We ensure the web app has the same app-like experience as its mobile version, regardless of whether it’s iOS or Android.

Our team of Montreal and Toronto app developers has a wide variety of programming language proficiencies to ensure that we are creating the best solution for your project. Most of our projects use technologies such as React, Angular JS, JavaScript, Ruby on Rails, Node JS, and Mongo DB to create fully functional web apps and a superior experience. As a technology-agnostic app development company, we’ll use the best web app programming language for your objective.
