Wikipedia
Since many folks probably just use Safari to access Wikipedia, you may not have even realized that there’s a dedicated app for the online knowledge service, and now that dedicated app also has some pretty cool widgets to keep interesting information available at a glance,
First there’s a widget for Wikipedia’s Picture of the Day, which will show you a different photo each day that you can tap through to learn more, with the large version of the widget also offering a descriptive caption. If you’re more interested in historical facts, the On this Day widget will show you significant historical events that occurred in years past, and lastly the Top Read widget will show you the day’s trending topics on Wikipedia.
