OnLeitner es tu compañero de estudio basado en el método Leitner, un sistema de repetición espaciada científicamente probado que te ayuda a memorizar cualquier materia de forma eficiente. CÓMO FUNCIONA Crea cajas temáticas y añade flashcards con pregunta y respuesta. El sistema Leitner organiza tus tarjetas en 5 niveles: cuando aciertas, la tarjeta sube de nivel y se repasa con menos frecuencia. Cuando fallas, vuelve al nivel 0. Así tu cerebro dedica más tiempo a lo que más te cuesta. PARA QUIÉN ES • Estudiantes de cualquier edad y nivel: ESO, Bachillerato, Universidad • Opositores que necesitan memorizar temarios extensos • Cualquier persona que quiera aprender vocabulario, conceptos o datos de forma efectiva TRUCO: USA LA IA PARA CREAR TUS CAJAS ¿Tienes apuntes en PDF y no quieres crear las flashcards una a una? Exporta una caja de ejemplo en formato JSON desde la app, pásale ese JSON junto con tu PDF a tu IA favorita (ChatGPT, Claude, Gemini...) y pídele que genere las flashcards en el mismo formato. Luego importa el archivo resultante en OnLeitner y tendrás todas tus tarjetas listas para estudiar en segundos. CARACTERÍSTICAS • Método Leitner con 5 niveles de repetición espaciada • Modo estudio guiado nivel a nivel • Modo estudio aleatorio para repasos rápidos • Cajas personalizables con colores • Exportación e importación de cajas en JSON • Exportación de cajas a PDF • Interfaz moderna y nativa en iOS • Disponible en español e inglés VERSIÓN GRATUITA Prueba OnLeitner gratis con hasta 3 cajas y 5 tarjetas por caja. Desbloquea la versión Premium con una única compra para disfrutar de cajas y tarjetas ilimitadas, además de las funciones de exportación e importación.
