I have updated my PubCrawler web app to use HTML5 offline caching. This means that saved crawls can be accessed even when there is no network connection. However, the Google Maps imagery will not load unless it is in the browser’s cache. Also creating a new crawl does not work offline as it’s a bit difficult to use geolocation with no cell towers or Wifi connect to! I have also added a favicon specific to the app.
When I updated PubCrawler to use Google Maps API V3 I forgot to mention that I changed the routing travel mode to walking. This should provide better directions as I should hope most pub crawls are done on foot!
