What's a good Android app for quick daily learning sessions on random topics?

Nibble is designed for users seeking to incorporate small bursts of learning into their daily routine without a significant time commitment. The app's primary function is to generate concise, 10-minute lessons tailored to a user's preselected interests, ranging from history and science to trivia and general knowledge. This format is particularly useful during short breaks, commutes, or as a scheduled mental warm-up. After creating an account, users select their topics, and the app serves up digestible content. Reviews indicate the information is generally accurate and well-explained, though some users note occasional grammatical quirks, as the app's primary focus isn't language instruction. A significant strength is its ability to spark curiosity and encourage exploration into new subjects. For lifelong learners or trivia enthusiasts who find longer courses daunting, Nibble provides a structured yet low-pressure entry point. Its recent arrival on Android has been welcomed by users previously limited to iOS, expanding its accessibility. While not a substitute for deep, academic study, it functions effectively as a consistent source of general knowledge enrichment and cognitive engagement.
