When creating the app, why not create a variety of menu options and then test them with users.
Card sorting is an excellent and fast type of test, which allows you as a UX Designer to step out from your own ideas and see what others think. To go even further, create a variety of menu options, think outside of the box and of course let other do it in the brainstorming session. Let others lead you in the ideation process by not giving them all the clues right on the table.
Here is just a small example e.g. Wellness Life App and Website, which offers physical as well as meditation classes, wellness therapy e.g. body massage and creative art and music lessons.
What do you think and feel about those options, which one is the clearest to you, and which is not, and why? What would you add, change, replace, or erase?
See, if any of the new types of menu will meet the successful outcomes by adding additional main categories such as contact, home, about section and subcategories, for example, art class, music class, massage types, yoga, pilates, mediation class etc.
Asking and Testing Listening while Observing is a MUST in UX Design. This not only boosts the outcome but will save a lot of hassle too. To satisfy your customers, ask users and then code the app or web not a positive way. Catch the errors earlier, while failing often to succeed in the long term.
