Sizeer mobile app


Out first task was to create a loyalty app based on a system of reward points, as well as other financial perks such as discounts or special offers. Next, we designed and implemented the sales application conjoining it to the already existing loyalty programme. The loyalty programme awards points not only for each purchase, but also on completing a series of tasks suggested in the app. An essential part of the app, which increased its value added, was to enable users to 'try on' shoes using Augmented Reality (AR).

What we did.

Thanks to a wide range of competencies, our team has successfully met the client's requirements. During stage one, our greatest challenge was to implement and integrate the multi-channel loyalty programme. Its attractiveness and at the same time technical complexity stem from the fact that the programme accumulates points from a variety of sources onto a single user account. Moreover, thanks to the use of AR, app users are able to try on shoes virtually, irrespective of where they are. The next stage was to allow in-app shopping. As a result, our team has created a native shopping and loyalty app for iOS and Android, both smartphone and tablet-friendly, which benefits from the latest technologies as offered by Flutter.
