On-demand delivery service of fresh groceries, ready-to-eat meals and household items in 10-15 min.

As a startup we needed a team of professional mobile app developers that would step in as an extension to our team to cover mobile development. This is when we contacted Diffco. In our project we already had iOS developers. But we had some problems with Android engineers. As a result, we launched that right on time, got approved in Google Store from the first time, and the developed app is working very smoothly. We got very positive feedback from our clients, aligned the speed of developing both apps (for iOS and Android) and raised a round of investment funding.
