Brethap is yet another meditation app (yama). Including a timer for meditation, it also allows you to configure a breathing pattern for you to follow. Your sessions will be saved, allowing you to monitor and view stats about your progress in either a list or calendar view. Duration, breath and other options are configurable through saved preferences. Breathing technique presets include 4-7-8, physiological sigh, among others.
Mappoff was created for and maintained by hikers. Because it is often neccesary to do MAPPing OFFline when in remote areas, Mappoff allows you to save map layers and tiles for later offline use. Additionally you can create your own waypoints or enable tracking to save hiking routes. There are several preset layers including the PCT Water Report, the Appalachian Trail, the Continental Divide Trail, the Pacific Crest Trail, among others.
