Which product should I work on?

One of the advantages of running multiple software products is that you can make them compete with each other for your attention.
For example, right now I run several profitable products. These are just some of them:
  • Treendly, making $1227/m
  • Groouply, making $1100/m
  • FastLien, making $936/m
  • Cart, making $920/m
Since all of the software products run under the same conditions (for example, I don’t do paid ads on any of them) which one makes more gets more of my attention.
That’s a good way to decide.
Which product will make more this week in your opinion?
