kwiko app is 100% free.
kwiko is available on both iOS and Android. Go to ‘Home‘ to get the links to the stores.
kwiko has many curated theme-based and level-based word lists.
kwiko uses a Spaced Repetition algorithm to plan your review sessions. Spaced Repetition is an effective vocabulary learning method that spaces out the review sessions of the words over time. The algorithm increases the time intervals between the review sessions until you memorize it.
As our algorithm calculates the best review times automatically, the app notifies you when you have words to review. You cannot start review sessions by yourself if the app hasn’t scheduled any word reviews. This way we save your time and help you learn the words in the shortest time possible. On average, you will spend 1,5 to 3 minutes of focused time on each word in total (if you combine all review sessions for a single word) until you master it.
Smart Reminders is one of the most useful features of the app. When you activate the Smart Reminds, the app sends you reminders when you a review session gets scheduled. This way you can stay on track and not miss your daily vocabulary reviews.
Our promise: we don’t send marketing notifications.
