Interesting Insight — with Apps in general I see it more differentiated.
There are several classes of Apps: I am really happy having the ONE City Bus provider App to commute and the 3 favorite Cinema Theater Apps because I do not need anything else in my home town. When it comes to food. I don't want to have an App for every Pizzaservice, Delih and so on it in the city — I prefer Portals (App) that let me choose among a variety of restaurants and food delivery services.
With regards to Bots you are missing on Bot who is promising some additional benefit currently not realy working at services like Siri and others. Watson from IBM might just add recommendations based on experience, global data and your personal habits which is far more than I can expect from a human call agent somewhere on the other side of the world.
