## What is Citizen Scientist?

Citizen Scientist is an app that measures your experience of urban or rural living in the moment. 

The Citizen Scientist app uses a technology called “ecological momentary assessment” to monitor how the surrounding environment affects our mental wellbeing.
This technology involves presenting people with a prompt at random times, inviting them to answer questions about their surrounding environment and mental wellbeing. 
After answering the questions, participants are also invited to take a photograph of the ground or floor where they are standing and/or a short audio recording of their current environment.

Once you start answering the questions you will be able to access an individualised report which summarises your experiences. 

In addition, Citizen Scientist integrates with the Health app to record information about geographical location data; participants can decide whether or not to provide this information.

The data will help us understand how different aspects of the surrounding environment affect mental wellbeing, and will be used to inform novel clinical interventions and the planning and design of healthier cities.

Participation in this research project is anonymous, and the information provided by individual participants is kept private and confidential.

### 3/5 — Flexibility for entries

*2025-07-18, version 1.1.9*

I love the focus on nature this app brings. However, I keep missing my time to review and have completed only one reflection therefore. I can’t easily find a way to change the timing of reflecting and would like the option of doing it when I am ready. Missing important data from people who are unable to stick to a routines schedule.

### 5/5 — Very well designed

*2025-05-16*

Super easy to use, just wish there was a widget. No ads or payments needed and quick.

### 5/5 — So far so good

*2025-04-18, version 1.1.5*

Good Interface and operates smoothy. Looking forward to doing my daily reflextions
