For Mobile DevicesThere are so many mobile device makes and models, operating systems and browsers out there, it is impossible to check out all of the combinations. Here are a few:
For most mobile phones/tablets (Apple, Android, Nook) : This is a "web app", it is not in the app store, it is a specially designed web page. Using the browser on your device go to SwimFone.info and bookmark it. (Doesnt seem to work on Kindle or Windows Phone.) If this doesnt work, go to SwimmingHoles.info and use the lower (state) map.
For all computers and devices, even when you don't have internet access: Take entire state maps/pages with you with the excellent (free) program POCKET. (Use the POCKET option to download as a web page, NOT as text)
If you have any comments or suggestions about the above, please tell us at mail@Swimfone.info
