Finally, flexibility is here. As a participant in a clinical trial, you may be asked to complete electronic diaries, questionnaires or feedback surveys during the study. For studies using the Zelta™ platform (a Merative-owned product), this app will make it easy. It syncs with the Zelta™ platform to allow you to enter data in either location, depending on where you are. This app requires an account with Zelta™ provided by your healthcare provider. This app does not eliminate webpage access, just provides an alternate connection for iPhone users. Data collected via this app is recorded in the same location as data collected via the webpage. Product Notes: • Once logged in, an agenda page shows you the available diaries for the current day • Push notifications enables the system to send reminders when you have diaries available
