## How it works

A 50-minute countdown starts at 50:00, counts down second by second on the browser clock, rings at zero, then counts up until dismissed so the overrun length stays visible.

## Worked example

A freelancer sets a 50-minute timer at 14:00 for client work on one project. It rings at 14:50, she takes a 10-minute walk, and starts the next block at 15:00 — three such blocks with short breaks cover a full afternoon.

## Assumptions

- The countdown relies on the browser clock; closed tabs stop it and background tabs may throttle the ring.
- The post-ring count-up is a reference display only — the timer does not log or store session history.
- No push notifications or server-side alarms are used; the ring is only as reliable as the open, audible tab.

## Common questions

### What is a 50-minute timer used for?

The most common uses are deep-work blocks (50/10 rhythm), therapy-style sessions, lessons and consults that need transition time before the next hour, and exam-section practice under realistic timing.

### How does the 50-minute timer work?

It counts down from 50:00 in seconds and rings at zero. After the ring it counts up until dismissed, so you can see how long past the mark the session actually ran.

### Is 50/10 better than the 25-minute pomodoro?

Neither is better overall. 50/10 suits work that needs long uninterrupted runway; 25/5 suits fragmented days and hard-to-start tasks. DeskTime's data on productive users (about 52 minutes work, 17 break) is consistent with the longer rhythm.

### Why 50 minutes instead of a full hour?

The 10-minute margin absorbs transitions, note-taking, and overruns — the same reason therapy's '50-minute hour' exists. A full-hour block back to back with other commitments leaves no room to reset.

### Does the timer keep working if I switch tabs?

The countdown usually continues while the tab stays open, even in the background, but the ring may be delayed or missed if the browser throttles background timers. Keep the tab open and audible for reliable rings.

### Can I use it for teaching or running meetings?

Yes — a visible 50-minute countdown paces lectures and meetings and ends them with a clear signal instead of a judgment call. Plan 45 minutes of content into the block to protect the ending.

### What happens after the timer rings?

It rings, then counts up until you dismiss it. There's no auto-stop or reminder loop — it's a browser timer, not a server alarm, so keep the device audible if the ring matters.
