English prepositions are small words, but they are easy to mix up. Even when you know the rules, a real sentence can still make you hesitate: in, on, or at? To or for? Preposition Pro helps you build natural intuition through short, personalized practice—without memorizing endless rules. After a quick assessment, the app adapts to your answers, identifies your weak spots, and intelligently revisits what you still need to practice. WHY IT WORKS • Short, focused practice with natural-sounding sentences • Personalized questions based on your answers • Smart repetition for difficult prepositions • Instant feedback after every answer • Six categories: time, place, movement, manner, purpose, and abstract usage • Recurring mistake detection and focused practice • Built-in vocabulary support while you learn • Daily goals, mastery levels, and detailed progress tracking • An interface available in eight languages • Works offline, with no account required SHORT, EFFECTIVE LEARNING Choose the missing preposition in each sentence and find out immediately whether your answer is correct. Practice for a few minutes each day or complete longer sessions whenever you have more time. START FOR FREE The Time category and up to 10 practice questions per day are available for free. An optional one-time purchase unlocks every category, unlimited practice, detailed statistics, and adjustable session length. No subscription. No ads.
