Memrise and Anki are solid alternatives that a lot of people find less repetitive than Duolingo - Memrise uses video clips of real native speakers which makes it feel more practical, while Anki lets you create custom flashcard decks so you're learning vocab that actually matters to you. For something different, try pairing an app with free YouTube channels like SpanishWithPaul or consuming content you actually enjoy (Spanish podcasts, shows with subtitles, music) because passive exposure sticks way better than another round of the same gamified lessons. The key is mixing methods instead of relying on one app - boredom usually means your brain's stopped being challenged, so switching between listening, reading, and speaking keeps things fresh.
