ok Spanish

With nearly 7,000 Spanish words, ok Spanish is a quick and efficient Spanish vocabulary builder, reference dictionary and a word-a-day app all rolled into one amazing app.
The ok Spanish app provides completely free access to the most common Spanish words and is designed for anyone looking for a reliable resource to steadily increase and grow their Spanish vocabulary on their own and at their own pace.
The ok Spanish app, by default, introduces the user to a new word every day. In order to grow one's vocabulary, the app works by keeping track of the words the users were exposed to (thereafter 'ok'ed) and testing them via quizzes using spaced repetition system (SRS) which has been scientifically proven to optimize memorization and retention of learnt vocabulary.
Additionally, the ok Spanish app also functions as a simple and straight forward reference English dictionary app that comes with a default inbuilt search function.
