For the last couple months, I observed Today extensions of some of iOS apps I daily use to see when those widgets are useful and how to justify developing one. It might be the mistake made by most of the news apps to update multiple times per hour: users can miss the key content, but the extension keep being refreshed in the background, the user experience is not improved. It’s interesting that I couldn’t find many retailer apps using widgets to attract users back in their app, it could be a softer way than notifications to update users, like Amazon with status order or Selfridges with just-in products.
