About this app

Win is a vocabulary learning app that makes Review mode available for every deck in the app, all 8 built-in decks and any custom decks you create, applying the same level 0–3 filter to whatever subject you're working on.

For built-in decks like Advanced English or Phrasal Verbs, Review mode quickly surfaces the most challenging words in those collections, the ones whose definitions are subtle, easily confused, or simply take more repetitions to fully secure in memory.

For custom decks you create, perhaps for a professional certification, a language class, or personal hobby knowledge, Review mode works identically, filtering to weak-spot cards based on your actual performance history with those custom cards.

This deck-agnostic availability means Review mode is not a feature added on top of the standard experience; it's a core study option that applies everywhere in Betboom, treating all card content equally regardless of source or subject.

Whether you're drilling down on science terms you can't quite remember or revisiting Spanish words that keep slipping away, Review mode in Betboom finds your weak spots and puts them front and center without you having to identify them manually.
