The Pax app let's you set dosage controls so that you can always get a consistent hit each time. The new Era Pro even remembers the dosage based on which pod you're using, which is super useful for me since I have a sativa pod set to one dose and an indica pod set to two. The app also supports fine-grained temperature control in addition to surfacing information related to the pod like lab testing results.

There exist multi-cart vapes where you can load up 4 different carts (one THC, one CBD, one Terps, one Flavoring agent, as an example) and control the dispensed amount of each via phone app.
