I strongly disagree with the poster. We are in the best period of mobile apps, not the worst. During this period programmers are learning what can be done in the mobile environment and what can not be done well. The Android and Apple mobile environments are very much an exciting, experimental playground right now. The major problem cited is that mobile apps are inefficient, and that they slow down your phone. That won't be much of an issue in a few years, as processors keep getting faster and phones start to ship with 64 GB or memory or more.
Sure there are a lot of bad apps, but that's the point. Try out the bad apps, and learn what you should and should not be using your mobile environment for. Maybe what you originally thought was a bad app turns out to be quite useful for you. On the other hand, the most obvious mobile app might not be very useful. I make under 7 phone calls a week, but spend 4-5 hours per week using the Facebook app. At first I thought Instagram was fairly useless but today I use it more than Facebook. I don't fully know all of my use cases for my phone, but already it's an indispensible tool, and I find about 20-30 apps to be quite useful. Another 100 apps are marginally useful. The rest are as much an experiment for the programmers as for me.
The issue with permissions is being worked on by the Android developers. It's a separate issue.
In 10 years mobile apps will be quite stable. We'll have maybe 50 winners, and things will be quite boring.
