Stats from RSS parsing?

I have an iPhone app for my blog which simply parses the rss feed for wordpress.org blog that I use. The issue is that the stats always seem much lower than what I expect. For example, before I switched the app to parsing RSS, it simply directed people to the website of my blog. I could expect over 200 hits a day. Now, with RSS parsing, it only shows at max 89 a day, and that’s not the average. Is parsing the XML not registering a hit?
