This project was an assignment as part of our course Programming User Interfaces. I designed the mobile application screens and prototyped two screens / functionalities in Xcode, iOS.
We were given the prompt to design and prototype a iPhone app for helping smokers define a serious plan to quit smoking. The application was supposed to be persuasive and of course easy to use.
I began by researching and trying to understand the problems smokers face while trying to quit. This involved secondary research and talking to former smokers.
This was followed by a competitive analysis of existing applications which encourage users to quit smoking. I also looked at motivation and planning related applications which were not necessarily related to smoking.
Smoking has shown to affect one’s eating habits and users who quit tend to put on weight. Most smokers choose to smoke after or before meal times and as a means of taking a break. I wanted my application to help the user be more conscious of their existing habits; which would help them quit in the long run.
I started with low fidelity sketches and wireframes (Balsamiq) to flesh out what functionalities I envisioned in my application.
I decided to drop the social angle and narrowed in on the planning and tracking aspects of the application. Why? Most smokers I spoke to were intrigued by the idea of planning their day around meals and thought it was more important to see and record how much they were smoking. I proceeded to create hi-fi prototypes of my application. Further testing resulted in further changes as documented in these slides
Puff is an iPhone application that helps you track your smoking habit and encourages one to plan their day.
The dashboard showcases your progress. Too many smokes and you can see you image disappear gradually. It also shows you the money you are saving and increase in lifespan. These details help you monitor your progress quickly.
The timeline of the day helps plan your day. Add notes and alarms to remind yourself to eat healthy and stay smoke free. The tracker helps you enter how many smokes you have had. The tracker changed from a slider to a stepper in the final prototype for more accurate data entry.Below are screenshots of the application in XCode.
