Native iOS and Android apps for a marketplace platform.

About the client

Sprzedajemy.pl is a free online marketplace where users sell and buy services and goods. It is dedicated mostly to individual sellers. Users can verify each other’s credibility thanks to the integration with Facebook.

The company doesn’t charge commissions for transactions, and users don’t need to pay for adding offers. The platform enables contact between buyers and sellers which supports the decision-making and buying process.

The main objective was to create an application that would allow users to easily manage their classifieds, search for interesting offers and contact each other.

Our client wanted to build a product that would positively stand out from the competition.

Our goal was to make awesome mobile apps, which will knockout the competition. Also, we were focused on the budget, which was defined from the beginning. (…) Team was always willing to adjust their approach to ours, but they also suggested improvements they found effective in the past. We had a great support from the team.
