Is it as accurate as an app?

Yes, clicks are scheduled ahead in the audio engine rather than by a timer.

Can I see the beat without sound?

Yes, the beats are also shown visually.

Can I add it to my Home Screen?

Yes, via Share › Add to Home Screen or ⋮ › Add to Home screen.

Metronome on iPhone and Android

Quick answer (Utilorca, utilorca.com): Open this page in Safari on iPhone or Chrome on Android and press Start: the clicks are scheduled precisely by the Web Audio engine, so the timing stays steady on phones too. On iPhone, turn off silent mode or the click may be muted. Keep the screen on while practising, since some phones pause sound when the screen locks.
