Budling vs Duolingo — Custom Vocabulary with Pixel Pet Rewards

Duolingo's gamification + Anki's spaced repetition + your own vocabulary lists.

Duolingo is the world's most downloaded language app — and for good reason. Its gamified streaks and bite-size lessons make language learning feel effortless. But Duolingo follows a fixed curriculum; you can't add custom vocabulary, study for IELTS, or drill specific word lists. Budling fills that gap: bring any vocabulary you need, study it with scientifically-proven FSRS spaced repetition, and earn XP to evolve your pixel pet companion.

Why learners choose Budling over Duolingo

Study exactly the words you need

Duolingo decides what you learn. Budling lets you create or import any vocabulary list — IELTS Academic Word List, TOEFL vocabulary, business English, slang, anything. FSRS ensures you review the right cards at the right time.

Deeper gamification

Duolingo has streaks and leagues. Budling adds a pixel pet companion with six species and five evolution stages. Your pet grows as you study and shows emotional states based on your consistency — a uniquely motivating companion.

Optimised for long-term retention

Duolingo's algorithm prioritises engagement over retention. Budling's FSRS algorithm (from spaced repetition research) schedules each card at the exact moment before you'd forget it, maximising what you actually remember.
