Outdoor Map Navigator iOS
OMN - Outdoor Map Navigator (OMN) for iOS runs on iPhones and iPads running iOS 9 or later.
OMN iOS does not require an internet connection to run, but an internet connection will be required whilst initially setting up the software, downloading your maps etc.
However, once setup, you can leave your WiFi connection behind. If you are using OMN in an area which has a 3G/4G connection, and you have a suitable data contract, you can also access maps and sync data with Anquet Cloud, but this is not a requirement.
Please note whilst all iPhones have a built-in GPS, only iPads that have cellular capability have a built-in GPS. The software will work fine on a WiFi only enabled iPad, but will lack GPS capabilities such as real-time positioning and creating tracklogs. It is possible to buy a Bluetooth GPS and connect that to a WiFi only iPad to have the full system capabilities.
