Currently Epicollect5 allows a maximum of 300 questions per a single form, and a maximum number of 5 linked (hierarchy) forms.
The form builder features a three columns layout:
Left column: the available inputs
Middle column : the inputs added to each form
Right column: the currently selected input settings
By default, each input is shown on a single screen on the mobile app. This allows space for the popup keyboard and the question at the same time. You might want to have more than one question on a page, in that case just use a group.
You can use any UTF-8 language in your forms. The full list is here.
The mobile app instead is translated in the following languages:
