What is a heuristic evaluation?
Heuristic evaluation is a form of usability inspection where usability specialists judge whether each element of a user interface follows a list of established usability heuristics identified by Jakob Nielson.
Expert evaluation is similar, but does not use specific heuristics.
![Page 3: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/3.jpg)
However…
• Jakob Nielsen’s 10 heuristics were created pre-iPhone– Language and examples are not always
appropriate anymore
• The following report uses iPhone-adapted heuristics and examines any potential usability weaknesses that might confuse users.

1. Visibility of app status
The app should always keep users informed about what is going on, through appropriate feedback.
![Page 5: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/5.jpg)
Search doesn’t actually lead to search, it leads to browse.
![Page 6: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/6.jpg)
2. Match between app and the real world
The app should speak the user’s language, with words, phrases, and concepts familiar to the user and adapt to the user’s environment.
![Page 7: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/7.jpg)
The Flesch-Kincaid Reading Ease score indicates how easy a text is to read. A high score implies an easy text. In comparison comics typically score around 90 while legalese can get a score below 10.
Flesh-Kincaid Grade level: 20. The meaning (and even pronunciation) might not be apparent to the average users.

3. User control and freedom
Users often choose app functions by mistake and will need a clearly marked “emergency exit”.
![Page 9: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/9.jpg)
If I say no to him, there is no way to reverse it!
![Page 10: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/10.jpg)
4. Consistency and standards
Users should not have to wonder whether different words, situations, or actions mean the same thing.
![Page 11: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/11.jpg)
“Accept” is confusing here. If I wanted to chat with him, I could just start writing. If I didn’t want to chat right now, would he go into my “Connections”?
![Page 12: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/12.jpg)
When I touched Harlem Nights, it didn’t get added.
What’s a Date Card?

Not clear what the number next to the Carousel means.
![Page 14: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/14.jpg)
5. Error prevention
Eliminate error-prone conditions or check for them and present users with a confirmation option.
![Page 15: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/15.jpg)
![Page 16: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/16.jpg)
6. Recognition rather than recall
Minimize the user’s memory load by making objects, actions, and options visible.
![Page 17: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/17.jpg)
No ability to hide anyone from search.
I will need to remember whether or not I ruled someone out.
![Page 18: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/18.jpg)
7. Flexibility and efficiency of use
Reduce the number of steps required by anticipating user needs and enabling customization.
![Page 19: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/19.jpg)
I thought I could go here to customize what types of notifications I would receive.
I’m not sure what “Personals” means.
![Page 20: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/20.jpg)
While “Wink Reply” and “Mega Flirt” are attempts at efficiency, they have negative rippling effects of engaging with people you might not have on your own.
As a result, recipients can feel rejected or that they are being spammed by a robot.

8. Aesthetic and minimalist design
Screens should not contain information which is irrelevant or rarely needed. Every extra unit of information in a screen competes with the relevant units of information and diminishes their relative visibility.
![Page 22: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/22.jpg)
Coins feel like an action item.

9. Help users recognize, diagnose, and recover from errors
Error messages should be expressed in plain language precisely indicating the problem and solution.

10. Help and documentation
Help should be focused on the user's task, list concrete steps to be carried out, and not be too long.

Key Findings
• No glaring usability flaws, but several features could benefit from further attention.
• The following slides are “High” and “Medium” priority usability issues. All remaining issues are considered to be “Low”.
![Page 28: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/28.jpg)
High Priority Issues
• Efficiency– The Wink Reply and Mega Flirt are casting a wider
net than the user may intend. It can lead to feelings of rejection from messaged users that don’t get a reply.
![Page 29: Heuristic evaluation of zoosk app February 2014](https://reader033.vdocuments.mx/reader033/viewer/2022051412/548b48b0b47959e3338b468a/html5/thumbnails/29.jpg)
Medium Priority Issues
• Copy– Some of the wording is redundant or misleading.
The same terms should be used throughout (e.g. “date card” versus “profile”)
• Aesthetic– There is a call to action that is likely infrequently
used (coins in top left)

Conclusion
The heuristic evaluation of the Zoosk app revealed that there are a number of usability issues that the team can test with participants.
I look forward to testing the above findings with actual users of Zoosk.
