GeoSenEsm (Geolocation and sensor data supported ESM) is a tool developed for research project UrbEat but can be used by any study using Experience Sampling Method designs.

GeoSenEsm offers a ready mobile application for Android and iPhones and simple DYI setup instructions for server side admin portal. The application is shared under MIT license and is free to use. Study administrators install server side admin portal on their own server allowing them to retain independence and full control over data and study design.

Simple design inclusive for older respondents  - The main screen of the application is only dedicated to surveys. Surveys display only one question at a time and support large fonts.

Data security - all data is sent to and stored in one place only - researcher own server. The researcher is the only one who has access to all data.

Scheduling and notifications - set up start and finish time for your surveys, repeat them multiple times a day, respondents will be notified on survey start and when it comes to an end.

Fully operational offline - all surveys and responses are saved locally in the app and saved data are cached and will be uploaded as soon as there is an internet connection.

Admin portal - setup surveys and review results during the study using the admin portal. All study data can be exported to csv format.

Location and sensor data - Enrich survey data with geolocation and information on temperature and humidity from Xiaomi or Kestrel sensors (possibility to extend to others in the future). Limit the study to specific geographical region.

Open source and anonymous - setup your own server following our guideline, collect data with our mobile app, generate anonymous accounts for respondents. Researcher have full control over access to study.

Multiple question types and conditional routes - delegate question to subgroup from your study, setup conditional routes in survey, use one of six types of questions in your survey.

Privacy and data sharing - Respondents have access to shared sensor readings and locations and can limit the location sharing to specific hours of the day. Location data are shared with a one day delay to avoid live tracing of the respondents movements.
