Both Byki Express and Byki Deluxe guarantee that you will learn foreign words and phrases with Perfect Recall. That means after you learn a list you’ll be able to remember 100% of the words and phrases you learned, in both English and another language. As you finish Byki lists, you’ll feel your knowledge of foreign words and phrases growing, pooling into what feels almost like a language reservoir.

Tap into that reservoir.

You can visit the My Learned Items tab in Byki to see

• How many words and phrases you’ve learned (consisting of fresh and stale items)
• How many words and phrases may have grown stale in your memory since last time you used the program
• Your progress since you started using Byki Express

We call words and phrases “items” because each bit of language you learn sits on a shelf in your memory, like an item in a store. You can imagine that, after a while, some neglected items (in the back of the store on the left) can grow dusty and stale, needing to be polished or refurbished. In other words, your memory has to be refreshed.

See what happens when you click the highlighted “Refresh 10 Most Stale Items” button in the lower-right of the My Learned Items screen: you’ll review ten words that you haven’t seen in a while. After you’re done, those words will become fresh again in your memory. The pie chart will reflect that fewer items are stale, which means you still know them very well.

My Learned Items, while it may seem academic or unnecessary, is one of the most powerful features in Byki Express. It will guarantee that whatever you learn will stay fresh in your memory, forever, even if you learned it a year ago. Imagine going to France and realizing that you’ve forgotten all the French you ever knew. Byki stops that from happening.

Byki Deluxe has not only My Learned Items, but also a slew of self-testing options that let you fairly evaluate and track your knowledge as you improve over time. Testing and My Learned Items together make an incredibly powerful language-learning tool for anybody.
