Good except fo a major bug – GPSmyCity: Walks in 1K+ Cities Review

If your device has internet access, the app will attempt to access its server when it launches. This is ok, except for when the server is down. In that case the app is frozen, trying to reach the server. This is bad for an app that is supposed to run WiFi independent. A workaround is to put your device in airplane mode before launching the app, that will get you access to your stored city maps.
