Supported devices (with iOS version 7.x.x and higher. Ready for iOS 8.x.x):
• iPhone 4 and higher

Available Chart Folios cover coastal and offshore waters of North America, Latin and South America, Europe, Africa, Middle East, Far East, Asia, Australia & New Zealand.

iSailor is an easy-to-use navigational system developed for the amateur seafarers.
Intended for use on boats and yachts, iSailor provides a clear presentation of navigation information and electronic charts. Transas own TX-97 vector chart format supported by iSailor is recognized worldwide as one of the most accurate and reliable sources of navigational information. You can download your free version of iSailor software on iTunes Store.

All chart folios can be selected, purchased and downloaded via the iSailor app using its Chart Store section as per iTunes Store standard procedure for purchasing and payment.

Continued use of the GPS running in the background can dramatically decrease the battery life.
