SleepLearn

Build a stronger vocabulary routine with SleepLearn. SleepLearn helps you study and reinforce foreign-language vocabulary with two simple session types: active learning for focused practice, and calming bedtime review for a quieter routine before rest. Choose a language, pick your level, set a session size, and review target-language words with optional English translations, audio, repetition, and progress tracking. Use active learn sessions when you want direct vocabulary practice. Use bedtime review sessions when you want a softer, low-distraction way to revisit words at night. Favorites, known words, exposure history, and morning recall help you focus on the words that matter instead of treating every session like a one-off list. SleepLearn is designed around a simple idea: study intentionally, review calmly, and build consistency over time. Bedtime audio can support your routine, but it is not a replacement for active learning or regular practice. Features: * Active learn sessions for focused vocabulary practice * Calming bedtime review sessions with target-language audio * Optional English translation audio * Adjustable repetitions, playback speed, and pauses * Reinforcement through exposure history, favorites, and known words * Sleep timer with gradual volume fade * Ambient sound options for a softer session * Optional experimental low-volume sleep frequency layer * Morning recall practice for bedtime review words * Local progress, streaks, and session history * Support for Spanish, French, German, Italian, Portuguese, Russian, Japanese, and Korean * Offline-friendly vocabulary and prepared audio resources SleepLearn does not promise instant fluency, learning without effort, better sleep, or any health outcome. It is a reinforced vocabulary companion for learners who want active study, calmer review, and a consistent routine.
