How it works
An 8/8 metronome counts the eighth note, eight to a bar. Wikipedia's article on additive rhythm describes 3+3+2 over 8 as three beats: three notes, three, then two.

Start
Tap the pad, or press Space. The raised clicks fall on one, four and seven, with one the highest. Tap the pad once more and it stops.
Change the tempo
Tap the number under the pad and enter an eighth-note tempo, or nudge it with minus and plus. The new speed takes hold on the next click.
Questions and answers
How do you set 8/8 time on a metronome?
Count eighth notes. Eight clicks fill the bar and the number is their tempo, so for a score marked in quarter notes type twice its figure. This is a metronome with 8/8 already marked three, three and two; nothing more needs setting.
What is the difference between 8/8 and 4/4?
The stress, not the length: each bar holds eight eighth notes. In the additive rhythm article 4/4 has four beats of two eighth notes each, and 3+3+2 over 8 has three beats of unequal length. The 4/4 page clicks quarter notes instead.
Is 8/8 always counted 3+3+2?
No. Wikipedia's Time signature article also prints 3+2+3 over 8, and reports that the opening movement of Ravel's Piano Trio is in 8/8 split that way, after Basque dance rhythms. For that music this pad's third raised click arrives one note late.
Where does 3+3+2 turn up in music?
Wikipedia records two: its article on additive rhythm quotes a writer who hears a jazzy 3+3+2 in the coda of Stravinsky's Octet, and its list of works in unusual time signatures has the last of Bartók's Six Dances in Bulgarian Rhythm in 3+3+2 over 8.
Why can't I hear the metronome?
Start with the phone, not the page: is its ring switch on silent, its volume at zero, or a pair of Bluetooth headphones holding the sound? Eight dots light in turn whatever the answer, larger on one, four and seven.
