There are many timezone and world clock apps out there. However, they simply display the current time in various cities. If you wish to find out the time in Paris at 5pm local time, you would need to make mental calculations. "What is the Time" is the app that simplifies this process with just a swipe on the time ruler. Easily move time forwards or backwards and observe the city clocks update in real time. This feature facilitates planning for future meetings. You can personalize the city names with those of your loved ones, team members, or special memories. Sort the cities alphabetically or chronologically, or rearrange them manually in your desired order. The color of the city changes during the transition from day to night. No subscriptions or ads involved, just a one-time in-app purchase to access more than 3 cities.

Verdict
The clearest difference is monetization model: What Is The Time at free with in-app purchases against World Clock Pro's subscription. What Is The Time also leads on review sentiment (100% vs 77%) and update cadence (fortnightly vs every 2 months). World Clock Pro's advantage is ratings volume (1.4K vs 2) and iOS requirement (13.0 vs 17). On price, ads, in-app purchases and device support there is nothing between them.
