Starting data collection from a mobile device connected to a LabQuest 2 or LabQuest 3, via a Data Sharing app such as Graphical Analysis or Graphical Analysis Pro, will automatically store existing data and collect additional data in a new data set. This avoids unintentionally overwriting the original data.

In contrast, when data collection is started from the LabQuest, new data will overwrite an existing data set, unless you take explicit action to store the current run before starting data collection.
