Polimelo — Language Learning
Polyvo
"The smart way to learn English."
Smart Review System
Right word, at the right time.
Polyvo calculates exactly when you are about to forget each word and brings it to you at that precise moment. You won't waste time repeating words you already know; the ones you struggle with will appear more frequently.
A tailored implementation of the SM-2 algorithm: using learning → review → graduated phases, each word settles into your long-term memory.
Core belief: studying at the right time with the right method is far more effective than hours of rote memorization without reviews.
Study Modes
Flashcard
Cognitive-based card flipping; deep learning with word pronunciation, Turkish/English definitions, synonyms, and contextual examples.
Cloze
Guessing blanks in a sentence based on context. Allows you to learn words through natural and realistic usage structures rather than isolated word lists.
Test
Measure your knowledge with interactive multiple-choice tests. All incorrectly answered words are automatically rescheduled by SM-2.
Deeplearn
Advanced review session. Gives you full control over card sorting, difficulty factor, and focused study sessions.
Game Center
Learn. Play. Repeat.
All 4 active games are connected to the SM-2 system. Correct or incorrect choices made in-game update your learning progress. Playing games is studying too.
PolyFlip
Matching card game. Race against time to match the meanings of words in your memory as quickly as possible.
FlapyChicken
