Quipp Live Trivia

Launched the most successful EU-wide trivia app with more than 50,000 daily active users (DAU).

Quipp is a mobile live quiz show positioned between linear television and digital app products. It is aimed at all smartphone users aged 18 and over who miss the transient communal experience during their online media consumption, as used to be the case when watching TV quizzes with friends. This communal experience is further enhanced by fixing a live date daily at 8 p.m. and sharing the prize money among all winners.

The new quiz app fills a gap between the TV show and the classic app. It only works at a specific time of day and simultaneously facilitates a group experience with your group of friends. The interface is consistently oriented towards the user and is constantly being optimized. A minor sensation that brings linear TV up to a contemporary level.

Deaf Accessibility Application

The first of its kind mobile app for the inclusion of deaf and hard-of-hearing people in public organizations and schools.

TotalK is the first application in the country providing equal access for deaf and hard-of-hearing people. It had two mainstreams, a video relay service and a speech transformation to text. It was widely used in public organizations, banks, railway stations, and more than 60 public schools in a joint effort with the Ministry of Education.

UHRD Audio Streaming

Created a robust MVP scope for a next generation mobile audio streaming platform

As part of the scope of work, what had to be created was a robust MVP, select technical vendors, and create all the user journeys and flows. Worked with the development team, leadership team, and UX.
