Evouchers is an initiative of Wonde - a portal for managing school data - and it was initially created as a simple solution for schools and local authorities in the UK to procure, assign and distribute grocery vouchers during school holidays or self-isolation during the 2020 Coronavirus pandemic.

They found great potential in flexible digital voucher solutions that support organizations, from corporations to not for profits to Government bodies. And finally, they have worked hard to develop a robust system that is ready to fulfill any voucher requirements.


Wonde team was about to develop a few new ventures and side projects for their core business. One such initiative was Evouchers for which they wanted to find a long-term partnership to support them with the current and future initiatives.

They built all of their desktop apps internally but decided to find a partner who will assist them with mobile projects. One of the main project objectives was to build a mobile app both for iOS and Android, based on designs they made. They were additionally very keen to use React Native, as they've already used it in another project and wanted to keep the same stack everywhere.

  • Main Features on Evouchers - mobile app for redeeming vouchers
  • View on the Transaction for logged users in Evouchers mobile app

As Wonde Team wanted to build cross-mobile app and had some good experience with React Native, we decided to go this way. One of the most important factors helping in the entire planning and development process was the fact that we spoke directly with the CTO and the decision-maker right from the beginning, so we could proceed much faster with decisions. We have divided the project execution into 4 sprints.
