MERlite is a scaled-down version of MER, used and aimed at data gathering and transmission to and from MER. This tool can inherit data gathering variables from the MER system and allow for rapid data gathering and transmission to MER.

It is aimed for novice computer users and/or low-tech remote site use of software. It must be noted that MERlite will only handle data related to monitoring (MER log-frame part B) and management data.
