One tracks the hours. One picks them.
Session is one of the most carefully instrumented focus timers available. It syncs a running session between Mac and iPhone, keeps full logs and analytics, mutes Slack while you work, reads your Apple Calendar and writes finished sessions back into it, and is automatable through Shortcuts and AppleScript. As a piece of Mac software it is genuinely excellent, and the ratings reflect that.
None of that answers the question DuckDoro exists for. A perfect record of your focused hours tells you what you did; it doesn’t tell you what to do. If your week is well-logged and the important thing still hasn’t been started, more instrumentation is not the missing piece — a decision is.

On paying once
Session is subscription-priced — roughly $5 a month or about $40 a year, with a real free tier underneath that plenty of people use indefinitely. There is no lifetime option, and that appears to be a question they field often: their own homepage FAQ carries the questions Why subscription? Would you consider one time fee plan?
and Other Pomodoro timers offer a free product or a one-time purchase. Why should I pay for Session?
We won’t characterise their answers — they load in-page and we can’t quote them accurately — but a company putting those questions in its own FAQ tells you the request comes up.
DuckDoro sells a $99 lifetime and intends to keep selling it. That isn’t a criticism of subscriptions; it’s just the thing we can offer that most of this category no longer does. Two other honest notes: Session’s blocking and global shortcuts are Mac-only features, and DuckDoro runs anywhere there’s a browser, including Android — which matters if your work isn’t all on one Apple machine.
Who should keep Session
- You bill clients, or you need a defensible record of focused hours.
- You live on a Mac and want the timer wired into Slack, Calendar and Shortcuts.
- Time-blindness is your issue and reviewing the log is what helps.
- You want site and app blocking during sessions — DuckDoro has none.
Honestly: keep it. DuckDoro’s analytics are deliberately thin, and thin is not what you need.
Who should try DuckDoro
- Your logs look productive and the important thing is still undone.
- You want the day capped, not measured. (Why three.)
- You work across a PC, an Android phone, or someone else’s machine.
- You’d rather pay once.
Or use both: DuckDoro to choose the three and name the frog, Session to time and log the work on your Mac. Deciding and recording are different jobs. Feel the deciding half in under a minute with First Bite — no account.
