Oh, that's interesting! What type of tutorial would be handy? I know there is a build in tutorial, but what does it lack? Would making it more involved with the contxt better? Would it be a good idea to have more personal coaches available?
Edit: I have a lot of questions which I posted under the reply of the previous user. I'm very interested in how I can taillor the tutorial or provide a way to make the current tutorial better!

From my experience there are tutorials but they do seem like a hassle to follow. I don't exaclty know how to improve them. Do I involve theplanning, mood, experience with non-visual devices and experience with the phone? What factors do I need to involve to make it better? Would duolingo(courses like learning a language) be a good example of how a tutorial could work or should I approach it the NS reisplanner(the dutch website and app to plan a railway journey: you can change the start point and end point and stops in between, the start or end time and see how long it takes and which steps and alternatives you can follow) or the should I approach it a different way? Would it be a good idea to have more personal coaches available? Which contextual things do I need to take into account during the learning process? I know that people become more stressed when they have a lot of things going on in the background, which might be related to the amount of things a person has planned to learn and how recently the person started using the phone non-visually.
