From what I've seen, the teams that are actually on the fireline mostly use paper ICS 214s and radio. The structured digital stuff lives at the ICP/EOC level. So the gap is really between field collection and the management system — if you can get a compact record off a phone with no connectivity requirement, that bridges it without asking anyone to change their workflow.

I think the practical win is SALUTE-style reports that auto-populate grid and DTG, exportable as plain text. No one wants another app to learn at 0200 on a fire.
