Digitize your EGMA and EGRA data collection with Tangerine.
Full Description


Digitize your EGMA and EGRA data collection with Tangerine. Create your Assessments online, conduct them offline with the Tangerine Android App. All results you collect can be exported as a spreadsheet. Tangerine has been used by over 30 organizations to conduct over 1 million assessments and surveys in over 50 countries and in 100 languages.


We recommend using AWS for hosting have documented detailed instructions for AWS. Below are general instructions for installing on any machine.

SSH into your machine from a terminal, install Docker, and then run the following commands. You'll need the version of the most recent release. Find that on the releases page here.

# Get the software.
git clone
cd Tangerine
git checkout <version tag>
# Create and edit to match your desired settings. Make sure to set `TANGERINE_VERSION` to the same as what `<version tag>` in the prior commands.
# Start the software.

If your server restarts or the container stops, you can later run the ./ script in the Tangerine-server folder.

To use SSL, put an SSL enabled Reverse Proxy in front of Tangerine and set the T_PROTOCOL variable in to https before running At RTI we use AWS's Elastic Load Balancer in front of Tangerine because it automatically renews and cycles SSL certificates for us. How to set this up is detailed in our instructions for AWS. If your Tangerine install is on a Digital Ocean Droplet, you can use their Load Balancers and configure them for SSL. See How To Configure SSL Termination on DigitalOcean Load Balancers.
Now visit your Tangerine-server installation at the IP address or hostname of your installation. In this configuration, the browser talks to the Load Balancer securely on Port 443 while the load balancer communicates with Tangerine Container on port 80 on a private network.


SSH into your server and run the following commands.

cd Tangerine
git fetch origin
git checkout <version tag>
# Set up again.
cp config.sh_backup
# Migrate settings from config backup to Set TANGERINE_VERSION to the same <version tag>.
vim -O config.sh_backup
rm config.sh_backup

Note that if you have created groups already and you are now updating T_HOST_NAME or T_PROTOCOL in, you will manually need to edit the settings docs in each group. See issue #114 for the status of this.

Development method 1: Use to map code directories into a Docker Container

Prereq: Install Docker.

Clone the repository.

git clone
cd Tangerine

If you are using a text editor or IDE such as Webstorm on your host machine, your
file modifications may not trigger the ng build process on the docker instance.

If you use Idea Webstorm, please try turning 'Safe write' option ( Settings | Appearance & Behavior | System Settings | Use "safe write" (save changes to temporary file first)) off

Run these commands to start get docker working inside your shell:

docker-machine start
eval $(docker-machine env default)
cd source/Tangerine-Community/Tangerine
