Flowtime vs Third Time

How Flowtime works

Flowtime was described by Zoë Read-Bivens as a direct response to Pomodoro's fixed intervals. The principle: work without a timer until you naturally want to stop, note your start and end time, then look up your break in a table based on how long you worked.

The original break table looks roughly like this: under 25 minutes of work earns 5 minutes of break; 25–50 minutes earns 8; 50–90 minutes earns 10; over 90 minutes earns 15. The break is prescribed by the bracket your stint falls into — not a continuous calculation, but a stepped one.

The result is a method that preserves the flow-state advantage of Pomodoro alternatives (no bell, no forced interruption) while still giving you a concrete break recommendation at the end.

How Third Time works

Third Time shares Flowtime's core move — variable work, break proportional to effort — but replaces the lookup table with a continuous ratio. Every minute worked earns a fixed fraction of a minute of break. Default is one third; you can set it anywhere from one half to one sixth.

The other difference is banking. In Third Time, break time you don't spend carries forward to the next break. A short rest after a long stint doesn't waste the remainder; it waits.

The break calculation: tiered vs continuous

Flowtime's tiered approach means two stints of different lengths can earn the same break. 27 minutes and 49 minutes both fall in the 25–50 bracket and both earn 8 minutes. That's simple to apply, but it means a 27-minute stint is rewarded as generously as a 49-minute one — the ratio isn't consistent.

Third Time's continuous ratio is the same at every length. Forty-five minutes earns fifteen; ninety minutes earns thirty. There's no bracket to look up, and no jump between categories.

For most practical purposes the difference is small. But if you care about fairness in the work-to-rest relationship — especially across days with varied stint lengths — the continuous ratio is more principled.

The banking difference

This is where the methods diverge most meaningfully in practice. In Flowtime, a break that isn't fully taken is simply not taken — there's no mechanism to carry forward unused rest.

In Third Time, the break bank accumulates across every stint. A short break after a long morning session leaves the remainder available later in the afternoon. The total rest you've earned is always visible, which changes how breaks feel: they're not something you squeeze in between work blocks, they're a balance you've actually built up.

Which one to use

If you want a minimal method — just note your start and end time, take the recommended break, move on — Flowtime is easier to run. The lookup table is simple enough to memorise, and it requires no running total.

If you work in variable sessions across a long day, have stints that vary a lot in length, or want unused breaks to carry forward rather than disappear, Third Time is the more complete system. The bank gives you an honest account of what you've earned and what you've spent, across your whole day.

Both are better than Pomodoro if the fixed-interval bell has been your problem. The choice between them comes down to whether you want a simple lookup or a running balance.
