When should I use Wepi and when should I use Voozanoo?

If you are not sure whether to use Wepi or Voozanoo for your next information collection project, consider the following.

Wepi was designed to be used by non-technical people. As such, we didn't want to make it complicated with lots of functions -- therefore it will necessarily have limits. Wepi allows you to create a questionnaire and distribute it (make it available via the Internet or on smartphones or tablets as an application) to many people, or to have a handfull of people fill it in multiple times, creating many records. It is ideal for a case report form or registering people to be part of a group or any “one-shot” data collection activity. It allows you to collect information about something over one determined time period, for exemple, a disease outbreak, collecting specimens, logging auto accidents, collecting opinions or votes, or other cases of an “event”. These are acticvities where you will not need to go back to the event and add new information later.

If you need to collect information over time on an individual, an animal, a plant, or some entity subject to change over time, Wepi would not be the right tool. Often, one first wants to enter information about an entity, such as its name, date of birth, sex, or other characteristics that identify this entity, a sort of initial registration that doesn't change. Then, every day or week or other time period, one will want to collect changing status information about one of those particular entities. For example, in patient care, it might be important to save the patient's blood pressure, pulse, and weight information. This can be considered as monitoring, surveillance, or follow up over time. Thus, one can see that the values taken over time need a specific database structure which is known as a relational database. Voozanoo allows you to make this kind of information system, Wepi does not.​
