English practice for adults · Android
Learn English by writing the answer yourself.
Stelesy is a serious English learning app for adults who already know the basics. Translate complete thoughts, see what your answer communicates, and return to the words that need another attempt.
One attempt has a clear job
Turn a thought into an English sentence.
Every Stelesy task starts in your task language and asks for English. You type the answer before you see a reference. That puts vocabulary, grammar, word order, and meaning to work in one place instead of drilling them apart.
- 01
Translate complete thoughts, not isolated word pairs.
- 02
Construct an answer before feedback appears.
- 03
Practice English you could use in work and everyday situations.
A result you can investigate
See the task, your answer, and a reference side by side.
After you answer, Stelesy prepares a natural reference for that task and evaluates the attempt for meaning, structure, and word use. It is not looking for one prewritten sentence typed back word for word. When a difference deserves an explanation, you can open a focused Grammar chat about that specific point.
Spaced repetition, word by word
A hard word should return sooner. A solid one should make room.
Stelesy records word-level evidence from an accepted answer. New words calibrate through real use, uncertain words come back sooner, and words with stronger recall wait longer. A fixed deck does not decide what you repeat next.
Practice that has a reason to appear now
The next sentence follows your current learning state.
Stelesy selects practical English around your current difficulty, brings weak words back in useful context, and gives priority to unfamiliar words you choose to learn. There is no generic lesson order to follow.
Progress is something to inspect
Use the history to decide what needs work.
Analytics separates how deeply a word has settled into memory from how ready it is to recall now. You can also inspect rating direction, daily activity, sentence coverage, and the history behind an individual word—signals for decisions, not decorative rewards.
Built for a particular kind of learner
For adults who already have basic English and want to use it better.
Stelesy is for deliberate practice: professionals and students who can understand some English but want to write and speak with more control. It is not a first English course for absolute beginners, and it does not try to turn serious practice into a game.
