Desktop and Android monitors solve the same event problem with different constraints. Choosing wrong usually means battery death, a blocked port, or a machine that cannot sit in a bag.
Long sessions, multiple rooms, large charts, and webhook fan-out all prefer a plugged-in Windows machine. Keyboard shortcuts and a second monitor reduce misclicks during gifts.
A phone in a pocket can follow a single room while you are away from the desk. Foreground services and notification channels matter more than chart density. If the OS kills the process, you have no archive.
Hotspot plus 24/7 capture plus screen-on is a thermal problem. Use a charger, disable unused radios, and test a four-hour run before you trust the device on a real show.
Phone alerts should be reserved for thresholds you will actually act on. Desktop can show more toast noise because it is not in your pocket during dinner.
Use the same room list, the same gift thresholds, and the same archive naming on both platforms. Tool switching should not require a new mental model every night.
