Opzio uses a combination of generalistic trackers and application specific trackers.
Some apps let you install addons/plugins, others don't and for the latter we need an OS installable tracker.
You can use as many you want to! In fact, the more trackers you use, the better Opzio is able to understand what you're working on and create a more accurate profile. Feel free to use only those that make sense to you and your organization.
