Our talented in-house app developers are very knowledgeable about IoT application development and have experience in building Internet of things digital products. With so many OEMs (original equipment manufacturers) adapting and creating IoT friendly devices, opportunities for 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 definitely opened a lot of doors when it comes to mobile app development.


After the Pokemon 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 to your digital product is a great way of creating real-life experiences, simulate training or product experiences, or add virtual adventures to your marketing stunt. Take advantage of our AR app developers skill-set to enhance your product experience by adding an AR/VR engagement element to it through a mobile app.



As an app development company, we love working with beacons. They are 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.


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


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

Web Apps

Web App

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


We’re experienced on building cross-platform mobile apps and web applications. We always make sure the web app has the same app-like experience than its mobile version, regardless if it’s iOS or Android.


Our team of 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 with a great experience. As a technology agnostic app development company, we’ll use the best web app programming language for your objective.
