These events may be related to each other, but they also may not. It's hard to tell with just one day. So continue to log events in your life and eventually you may start to see a pattern. That's what this app is for.
Currently, I haven't published analytics helping the user gain insight into what the data is telling them. That's because I'm still working on that. I personally have roughly five months of data logged now. I have several queries, and I'm working on teasing out the best views into the data. In the mean time, you can start logging your life. When you have enough data to start seeing patterns, I'll probably have the analytics nailed down, and will update Tap Tracker with pretty charts.
