Request for evaluation of 'Jeeves' - a tool for experience sampling study creation

As part of my PhD in Computer Science, I have developed 'Jeeves', a tool to allow researchers to create mobile apps for running Experience Sampling Method (ESM) or Ecological Momentary Assessment (EMA) studies. 

I would greatly appreciate any feedback on Jeeves from those with experience or an interest in ESM/EMA research. 
The Jeeves desktop application and the Android app are currently available to download from our research group's website at

We currently have Jeeves installers for Windows and Mac machines, and the Android app should work on all devices running the KitKat OS or above. 

If you are interested in the original source code, the desktop and Android applications are available at

If you would like to know more about Jeeves, please ask any questions you have here, and leave your contact email in the question following. 
If you have or would potentially be interested in conducting EMA in research or practice, it would be a great help to me if you would be willing to participate in future research. If so, please also complete Questions 3,4 and 5.
