Hill Lists is a comprehensive app for hill walking enthusiasts who are looking for a tool to help them track their progress and organize their walks. Developed by Graham Haley, this app has been around since 2009 and has since become a popular choice among hill walking enthusiasts in the UK and Ireland. With data for almost 20,000 hills and over 90 lists including Munros, Corbetts, Grahams, Donalds, Furths, Marilyns, Wainwrights, and Outlying Fells, this app provides almost a lifetime of hill walking opportunities.

The app offers a variety of features, including the ability to view each list on a map, sort lists by various criteria, and track completed hills by ticking those you have climbed, adding the date and any notes for each ascent. You can also share your location by email or SMS/text when you get to the top of each hill, view statistics of your ascents, and backup your data and sync it between devices using iCloud, Dropbox, AirDrop, or email. The app is available on iPhone, iPod Touch, and iPad and supports multiple ascents per hill and multiple rounds of lists.
