H4essential Control is an app that enables wireless control of the ZOOM H4essential Handy Recorder.
An iPhone, iPad or iPod Touch can be used as a remote control for an H4essential.
In addition to the fundamental operations of starting/stopping recording/playback and searching forward/backward, this app can be used to add marks and to set various parameters.
The app can also be used to check the waveforms of input signals and the remaining battery charge as well as to monitor the remaining recording time.

Note: A BTA-1 wireless adapter is necessary to operate an H4essential with H4essential Control.
