If you’re considering using LifeTopix with a parent, spouse, business partner, family member, etc., you can use Dropbox sync to sync everything across devices. However, if you have your own personal checklists, calendar items, etc., you currently cannot keep these items private. If the items you wish to share are not numerous (a trip here, an event there), then you can use email sharing to share those items. However, this feature is limited to not include any media or documents (photos in a trip, for example). In the future, we plan to support share/privacy settings for sharing across users. However, for now, you can use the email sharing option if you want to share a few things (shopping lists, projects, trips, events, notes). By tapping and holding the LifeTopix item that’s shown in the email message, the item is opened in the LifeTopix app.
