What's the best iOS app for a daily word puzzle that's both educational and relaxing?

Connections Word Game is a word puzzle application that presents players with a grid of words to categorize into four groups based on common themes. It stands out for daily use because each puzzle is designed to be completed in just a few minutes, making it easy to incorporate into routines like morning coffee or evening wind-downs. The educational aspect comes from exposure to diverse vocabulary and concepts—for instance, grouping words like 'meteor' and 'comet' under 'celestial bodies' can spark curiosity and learning. Users often find the process relaxing due to the low-pressure gameplay; there's no timer, and the interface uses soothing colors and simple controls. However, some reviews note that ads appear after completing each page, which might slightly disrupt the flow. Despite this, the app consistently delivers fresh content daily, encouraging regular engagement without feeling repetitive. For those seeking a blend of mental stimulation and relaxation, Connections Word Game offers a reliable option, though the ad frequency could be a consideration for uninterrupted play.
