Nielsen’s 10 heuristics evaluation of health coach Noom

←-Noom Heuristics Evaluation — ->

  1. Visibility of system status

The system should always keep users informed about what is going on, through appropriate feedback within reasonable time.

2. Match between system and the real world

The system should speak the users’ language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. Follow real-world conventions, making information appear in a natural and logical order.

3. User control and freedom

Users often choose system functions by mistake and will need a clearly marked “emergency exit” to leave the unwanted state without having to go through an extended dialogue. Support undo and redo.

4. Consistency and standards

Users should not have to wonder whether different words, situations, or actions mean the same thing.

5. Error prevention

Even better than good error messages is a careful design which prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action.

6. Recognition rather than recall

Minimize the user’s memory load by making objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate.

7. Flexibility and efficiency of use

Accelerators — unseen by the novice user — may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions.

8. Aesthetic and minimalist design

Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.

9. Help users recognize, diagnose, and recover from errors

Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution.

10. Help and documentation

Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused on the user’s task, list concrete steps to be carried out, and not be too large.

Notes:

-They do not have all food items logged into their database. I had a salad from a chain called Freshii and they only had a few items from that company. I had to go to their site to look up calorie info and they said “thanks for updating us.

-They have a bar code to scan and enter in meal if barcode is available.

-There are quizzes gauging your basic knowledge of health expectations (ex: how many steps you should take per day) in order to educate you on how to better incorporate health into your lifestyle.

-Encouragement for use of a pedometer and will incrementally add 300 more steps each time you reach your goal in order to reach the ideal target range. Gives recommendations on how to increase your walking each day.

-When entering in how many cups of coffee it wasn’t clear to me how to make sure that the amount was entered.

-Has trigger coaching and education.

-It says that the app is linked to my phones health app but it is not registering, it was not clear on how to link the health app on my phone to the noom app.

-prepares you for the next days activities.

-There are 9 steps to go through each day with articles and quizes involved that can be time consuming.

-The daily tutorials are time consuming and on the 4th day I decided to time myself and it took me 16 minutes and 20 seconds to go through all of the weight and food logging as well as reading all of the articles and taking their quizzes throughout the 9 steps.

-There is no way to go back and view your daily food logging all in once place. It would be nice to see that in one place and not individually going back through each date on the calendar.

-Gives you analysis on your daily food intake based off of their color coded system. This seems helpful. Although if your food item is not in their database it does not include that meal into their analysis

-Noom’s “goal Coach” sent me a text message when I did not log into the app over the weekend:
