Altitude App Main Screen



This project was created as part of my UXDI course. The client was a start-up airline looking to create a mobile app that provides a fast, easy and intuitive experience. One that’s based on a deep understanding of their target users.


Create a mobile app, specifically focusing on the flight booking process; how users search and select flights online.



Survey, Competitive Benchmarking, User Testing, User Interviews


Research Objectives

• Find out how people prefer to access airline prices
• Find out paint paints and negative experiences with existing apps
• Find out the improvements people want to see in travel apps


52 people took part in the survey, hosted on Google Docs. Friends and people from different Facebook groups were invited to take part.

User Testing Sessions

User testing sessions were carried out looking at existing flight and travel apps. At the beginning of the sessions an interview was also carried out. I then played back the recordings of the sessions, documenting highlights from the interview and making detailed notes as each user undertook the set tasks.
