Commissioned app development

Quantinar Q2 System

JS Insights provides cross-platform app development for the Quantinar Q2 System, bringing its learning experience to mobile and desktop devices.

Our commissioned work covers app builds for iPhone, iPad, Mac, Windows and Android. Quantinar is a client project, separate from JS Insights’ own products; our role is application development, not ownership of the Quantinar brand or the wider Q2 System.

Explore the Q2 ecosystem on these external websites. App test access is requested separately below.

Request a place in testing

Apple testing uses invitation-only TestFlight. Private Windows and Android test builds have also been prepared. Email us with your device and operating system to ask about the appropriate testing route.

We will confirm current build availability, compatibility and any invitation or approval requirements before providing access. Sending a request does not guarantee a place or immediate approval.

Have an app project in mind?

Share your intended users, core tasks, target platforms and timeline. We can discuss the app scope, interface and testing needs, with scope, price and delivery agreed in writing before paid work begins.
