If you can actually get the walking tours to download, then this app is great, and they are a great alternative to paying for audio guides. However, it takes at least an hour for one track to download, and the app has to remain open the whole time, or it stops downloading. You cant even let your phone go to sleep. I also had a lot of problems with just getting tracks to download. Numerous times they just "failed" or the app would crash when I opened them.
