The short version: World Clock Pro downloads for free, but time conversion, weather and its timezone database sit behind a $0.99/month or $8.99/year subscription. Clocker is a genuinely free alternative with no gated tier. Dato is an $18 one-time menu-bar clock and calendar with no subscription at all. If your actual need is finding and booking a meeting across a distributed team, not just seeing the time, Atlas ($4.99 one-time) goes a step further than any of these three.
World Clock Pro's App Store page leads with "free", but the features most people install it for need a subscription. If that's not what you want, here's an honest look at the alternatives that are free or one-time from the start.
Clocker: free, no gated tier
Clocker is a free, open-source Mac menu-bar world clock with a time slider, sunrise and sunset, and per-city notes, no subscription, no in-app purchase, and no feature held back behind a paywall. If World Clock Pro's free-but-not-really model put you off, Clocker is the direct, fully-free equivalent.
Dato: a one-time menu-bar clock and calendar
Dato goes further than a pure world clock: it's a highly customisable menu-bar clock, calendar and world-time display, sold as an $18 one-time purchase with no subscription. It's a bigger, pricier tool than a dedicated clock app, but everything you pay for is included from the first launch, nothing gated behind a later subscription tier.
What none of these three do
Clocker and Dato both show you the time in several places; neither maps a whole distributed team's working hours, suggests the best meeting time, or writes anything to your calendar for you. That's true of World Clock Pro too, once you're past the display features, it's still on you to work out the fairest slot and create the event by hand.
Where Atlas goes further
Atlas pins teammates and cities on a world map, shades everyone's actual working hours so the overlap is visible at a glance, then auto-suggests the best overlapping meeting time and adds it to your calendar in one tap, in everyone's correct local time, with daylight saving handled automatically. Every feature is included in the one-time $4.99 price, nothing held back for a later subscription tier.
Clocker and Dato are both good choices if all you need is to see the time in a few places. If the real job is finding and booking a meeting for a distributed team, that's a different, narrower problem, and it's worth picking the tool built for that job specifically rather than a world clock with scheduling bolted on.

So which should you choose?
If you want a genuinely free world clock with nothing gated behind a subscription, Clocker is the direct swap for World Clock Pro. If you want a bigger menu-bar clock-and-calendar tool and don't mind paying more upfront for it, Dato covers that for a one-time $18. If your actual problem is finding and booking a meeting across a distributed team, not just seeing the time, Atlas does that specific job for a one-time $4.99.
