Sleepmaker Storms Free is an iPhone application developed by James Sugrue. As part of the Education & Reference category, this app provides a unique experience of thunderstorms for a good night's sleep. With a wide range of storm recordings, Sleepmaker Storms Free offers both gentle and heavy storms, all perfectly looped by a motion picture Sound Engineer.

One of the notable features of Sleepmaker Storms Free is the inclusion of 3D Touch, which automatically remembers the last 3 tracks played. The app also features retina display graphics, an automatic screen turn-off to save battery, and a programmable sleep timer ranging from 1 minute to 23 hours and 59 minutes. Additionally, users can control the playback of previous and next tracks from the lock screen.

The app includes 25 tracks featuring 3 different forces of storms: gentle, medium, and heavy. From forest rainstorms to thunder with heavy rain, users can choose the storm that suits their preference for a soothing sleep environment.
