The iPhone and iPad are wonderful devices for using maps. But almost all map apps require a constant and strong data connection. What if you are using your wi-fi iPad out of range, or traveling away from your data provider, or simply sitting on a plane or in an area without coverage? ForeverMap is a simple map app that has one great feature: you can download and store street-level maps and access them offline. The downloads do take up a bit of space on your device, but that’s to be expected.
