PeakFinder offers a free trial version that allows users to explore basic features, but a full version requires a purchase or subscription for complete access.

PeakFinder can be used offline once the app and necessary maps are downloaded, although some features may require an internet connection for updates or additional content.

You can contact PeakFinder support through the app's help section or visit their official website for additional contact options and feedback forms.

You can manage or cancel your PeakFinder subscription through the app store settings on your device, where you can find subscription management options.
