The short version: World Clock Pro downloads for free, but time conversion, weather and its timezone database, the features most people install it for, need a subscription: $0.99 a month or $8.99 a year through its own App Store listing. It's also sold bundled inside Setapp from $14.99/month, but that price is for Setapp's whole catalog, not this app specifically. The subscription itself is genuinely cheap; the real complaint in reviews is being surprised that "free" didn't mean free.
World Clock Pro's own App Store page leads with "free", which is technically true only for the base download. Here's what that actually gets you, and what you'll pay once you need the features the app is built around.
What's actually free
The base app downloads at no cost, and existing longtime users reportedly still get the core clock for free under a legacy arrangement. For everyone downloading it new today, though, the features the app is actually built around, time conversion, weather for each city, and ongoing timezone database updates, sit behind a subscription. Several App Store reviews call this out directly, one reads simply "Requires a subscription! Not free!!!!!!!!!" That gap between the marketing and the real gate is the thing worth knowing before you install it, not the price itself.
What the subscription actually costs
Through World Clock Pro's own App Store listing, the subscription is $0.99 a month or $8.99 a year at the base tier (higher tiers exist too, up to roughly $2.99/month or $11.99/year, for additional features). That's a genuinely low price in isolation, cheaper per month than almost anything else in this category. It's also sold bundled inside Setapp, from $14.99 a month, but that figure is the price of Setapp's entire catalog of apps, not a World Clock Pro-specific number, worth keeping separate when you're comparing prices.
The real complaint isn't the price, it's the gate
Once you know the actual subscription cost, $0.99 a month is hard to call expensive on its own. The recurring theme in reviews isn't the amount, it's discovering that "free" only covers a shell around the features you actually wanted. That's a genuinely different complaint to "this costs too much", and it's worth being clear about which one you're weighing before you download it expecting a fully free utility.
How this compares to the rest of the category
Clocker is free. Dato is an $18 one-time purchase with no subscription. Atlas is $4.99 one-time. A subscription, however cheap per month, is still the exception in this specific category, most direct peers are either free or sold once. Some reviews also report daylight-saving accuracy issues, worth testing around an actual clock-change date if precise conversion matters to you.
What a subscription actually costs over time
At $8.99 a year, World Clock Pro comes to roughly $26.97 over three years, or around $35.64 over three years if you pay the $0.99 monthly rate instead of committing annually. That's genuinely inexpensive as subscriptions go, but it's still more than Dato's $18 one-time or Atlas's $4.99 one-time, and obviously more than free Clocker. None of these numbers should be the reason you pick one app over another, but it's worth having the real figures rather than assuming the cheapest-looking monthly price is automatically the cheapest option over time.
| App | Pricing model | Cost after 3 years |
|---|---|---|
| World Clock Pro | Free download + $0.99/mo or $8.99/yr | ~$27-36 |
| Clocker | Free | $0 |
| Dato | $18 one-time | $18 |
| Atlas | $4.99 one-time | $4.99 |
Before installing any app marketed as free, check specifically whether the feature that made you want it (here, actual time conversion) is in the free tier or gated behind a subscription. A five-minute check on the App Store listing avoids downloading something that turns out to be a demo shell.
Where Atlas fits
Atlas covers the same core job, seeing time zones and scheduling across them, as a single $4.99 purchase with every feature included from the first launch, no subscription, no gated tier, and nothing to reconsider later.
