KoBo Toolbox is a free open-source tool for mobile data collection, available to all. It allows you to collect data in the field using mobile devices such as mobile phones or tablets, as well as with paper or computers.
It is being continuously improved and optimized particularly for the use of humanitarian actors in emergencies and difficult field environments, in support of needs assessments, monitoring and other data collection activities.
If several partners are involved, try getting all partners in the same room and create the form directly in KoBo, rather than mailing around paper forms and then “translating” them into KoBo – it will give better results and is a faster way of designing the form
Try keeping your form as simple as possible, step by step instructions on how to use the different functionalities of the KoBo form builder can be found here
Use naming conventions, see link for general recommendations here, although there may be country-specific differences
If you need more complex functionality than what is available in the interface of the KoBo form builder, remember that you can always export your form and add the additional functionality in the Excel sheet (KoBo is totally synched with ODK), but do this only after you have finished the rest of your form. See here for links to XLSForm, Open Data Kit, how to create questions for scoring, ranking, P-codes and cascading lists)
If you need your form in multiple languages, follow instructionshere
Don’t forget to preview your form before saving and exiting to check for any spelling errors, errors in added logic, etc.
