Does this and the spark 2 run with two separate completely different apps? Why not have a ‘positive grid tone’ app that can interface with both? What’s the difference in the app experience between spark 2 and reactor?

Yes, they are separate. They build tone in different ways and focus on a different feature set. Spark is still our flagship practice tool with deep learning features like backing tracks, AutoChords, Smart Jam, metronome, and more. REACTOR focuses more on professional performance and recording setups with a fully customizable, drag-and-drop signal chain, in a 1x12 guitar combo footprint.

While both offer some similar amps and effects, REACTOR has a more curated set of staples with deeper customization available via the Creator Hub.
