What's the best iOS app for word puzzles that work offline during travel?

Wordgram Master is a word puzzle app designed specifically for offline entertainment, making it a standout choice for travelers. With a rating of 4.77 from Peace Word Studio, it offers a collection of decryption puzzles, jokes, and quotes that keep the brain engaged without needing data access. Users report that it excels in scenarios like air travel or commutes, where internet connectivity is often unavailable, and the app smartly disables ads in offline mode to prevent interruptions. The puzzles incorporate varied content, including references to pop culture such as Harry Potter, which adds depth but may challenge those unfamiliar with the material. However, some reviews indicate minor issues, like ad rewards occasionally failing to deliver or coins not being awarded after level completion. Despite these imperfections, the app's core strength lies in its reliable offline functionality and mentally stimulating challenges. For anyone seeking a distraction during long journeys, Wordgram Master delivers a balanced mix of fun and cognitive exercise.
