Mobile Application Measuring Skin Temperature & Skin Conductance with Smartphone

eSense app enables to measure current Skin Temperature and Galvanic Skin Response with the microphone input of smartphone or tablet. After all measurements, the user can start the meditation session. During the session, he/she can follow the body's response to image, music, video, colour change.
We offered custom mobile app development with application cross-platform technologies like Ionic and PhoneGap.

Our goal

The main goal was to create a mobile app with an intuitive design which will be used for tracking and monitoring skin response to various stimuli. The app should be easy to use so that the user is not distracted and could easily make all necessary measurements.


Cross-platform technology is not very suitable for use in the healthcare sector. So our developer had some difficulties with implementing this technology for custom mobile app development.

Application eSense is dealing with a large amount of information, therefore we had difficulties with recording and processing large data volumes. The program was not adopted for long measurements. The recording could take up to 10 hours and installed database could not handle this volume.

Also, due to the big data volume, in the application occurred issues with displaying the graphs. Indexes were recording every 0.1 seconds and it was challenging to keep records and display the precise chart. Chart JS couldn't present a large amount of data on the page.



In order to deal with data storage, we had to work with the database. As pouchDB showed poor performance for large volumes storage, therefore we were forced to switch to SQLite

To deliver quality graphic creating and displaying our developer created a proper algorithm. The algorithm enabled data compression and smoothing the graph.

We did our best to create an intuitive interface that seamlessly blends the three key user functions into one application.


Top three features are:

  • skin response
  • temperature
  • meditation and sessions

Skin response module: Module where the galvanic skin response is displayed. Our skin responds to external factors, such as stress, by the sweat providing. Application modulates the amount of sweat secretion of the skin and measures in microsiemens. In this way, one can measure the level of stress and observe how his/her body reacts to different stimuli.

Temperature module: Module where the body temperature measurements are displayed. You can choose either Fahrenheit or Celsius scale. Besides, the program will show you Max. and Min. value for every measurement session.Also, user can view statistics of previous measurements, they all are recorded and saved in the personal account.

Both modules allow running the meditation session, which consists of different parts, from listening music to colour change. During the session, user can observe how the temperature of the body and skin conductance response to various stages of meditation
