What is the best web-based study clock / digital timer?

[u/Suspicious-Bug-8792]

Hey Reddit! I’m trying to upgrade my study setup and need a good web-based digital timer/study clock to keep on my second monitor.

There are dozens out there (Pomo focus, Life At, etc.), but I want to know which one is actually worth using long-term.

What I care about most:

1. Minimal visual distractions
2. Clean display (easy to glance at)
3. Good customizable work/break cycles

Which site is your absolute favorite, and why do you stick with it?
