Why don't users pay for efficiency apps?

Hunter Walk in his blog that it's interesting to note that there is a flaw in efficiency apps, and they don't say what they really value to users, which is one of the main reasons why people don't want to pay.

There are too many efficiency apps that need to be paid to compare the free edition they give the user the impression that the difference is only in the way of use, or stay in the "paid version of a certain feature can really help me to quickly process information" on how much has been improved, my past speed, the use of tools, and then reached what level, Did not give a specific result.

He cited an example (pictured below) to show that the efficiency App "quantifies the actual value to the user" and "pushes the results to the user", these two points are important in stimulating the user's willingness to pay, not only to tell the user exactly what value you are offering, And the difference between your tools and the efficiency App, which is free of similar functionality, is no longer just "feeling" but the actual "data". He even thinks that even if the user doesn't know what you're quantifying (Walk doesn't know what the next "time on Phone" means), you just have to have a result that the user is willing to pay for.

Very strange, I saw this article, the first reaction is: "Quantify the actual value to the user", and "the results to the user"-these two points, not just now a lot of "look" of the hand ring products have been doing it?

and are people willing to pay for it? Still not.

When we're talking about why people don't want to pay for hand rings or smart hardware devices, the conclusion is that people need more than just simple data presentation, they ultimately need personalized improvement advice for their individual, in other words, you have to tell me how many calories I've spent in the day's passive movement, You have to go further and tell me some specific suggestions for improvement.

This, in my opinion, applies equally to the efficiency-type App.

In fact, "quantify the actual value to the user" and "push the results to the user" two points, is a lot of small and medium team collaboration tools already exist in the "newsletter" function, you can through the briefing, see how much work you have done, the efficiency of the situation. As for how you can improve your efficiency, there is hardly any specific advice to give you, or advice to stay on the default impression: You should use our app more.

How to do it further? I do not know. But what I do know is that I do have this demand. I need more than a simple data presentation, I have to know my current situation, can be more efficient? What should I do if I can?
