One intuitive way to categorize products is according to the observability of the value. In one class, it's readily apparent: the storage is cheaper, it doesn't fail very often, there's little downtime, my payments always go through, the user experience just feels better, all my friends use it. This doesn't have to be objective, just 'noticeable'. On the other hand, it's hard to judge the value of an encryption app, or a brain training program, because the true value is often hidden. It's difficult to tell, at least for the average consumer whether an encryption app works. There might be signs for the more immediately knowledgeable ('why won't the passwords take special characters, or passwords longer than 12 characters?'), but it's usually a small group. Unfortunately, this is probably going to make it harder for the latter kind of company to grow quickly, because trust takes time to develop. I don't just need to trust that my data will be safe - the entire value of the product depends on my trust that it does what it says. I have no idea if lumosity does what it claimed, but I doubt I could easily tell in a day or two. Contrast that with instagram or a better computer - the value (however large or small) is obvious.
