Does the SIBIONICS GS1 work with Apple Watch?

What SIBIONICS GS1’s own apps (SIBIONICS GS1 app, SiBionics Companion) do, from the maker’s documents.

No

The SIBIONICS smartwatch app runs only on Android watches. The GS1 app's iOS listing names iPhone, iPad and iPod touch, not Apple Watch. (SIBIONICS user guide, p. 6)

The GS1 is not FDA-cleared and is not sold in the US; these answers come from SIBIONICS's EU/UK English user guide, its sibionicscgm.com pages and the UK App Store.
