Move at your own pace, on your own schedule — but with a system behind you. Core is an independent learning experience, structured around you, that you work through on the web and in the mobile app with your guide cat Koko.

Every day, that day’s episode opens in four phases, right on time. You practice, you submit, the questions you missed come back at the end of the same day — and your plan updates around how you did.
Meet the day’s new structures, words and expressions. There is no clock and no hearts to lose in this phase — you go entirely at your own pace, with nothing to fear from a mistake.
Now you produce what you met in the morning: say it into the microphone, build the sentence, fill the gap, type it from memory. The clock and the hearts are live now — what counts is correct output, not raw speed.
The fastest phase of the day. Timers shrink, questions come one after another, and there is only one question left: can you produce it fast enough, without thinking?
You put the day’s material to work in real-life scenarios — and every question you missed that day is brought back to you here, one by one. The episode is complete when this phase is.
Each of the four phases targets a different skill and uses a different kind of drill. The names below are the real exercises you meet inside the lessons.
Four realms and the 40+ lesson types inside them cover every core area of the language — all of it in short, targeted sessions that compound over time.
Everything you need to know about the Core Package.
The Core Package is for students who want to improve their English on their own schedule but would rather follow a proper system than work at random. If you do not need anyone pushing you and can hold a daily rhythm by yourself, this is the right package. Coach support and one-to-one sessions are not included in Core — if you think you need those, Guided or Mentorship is the better fit.
Every day, that day’s episode reaches you in four phases: Learn (recognition), Activate (production), Automate (speed) and Consolidate (real use plus a replay of the questions you missed). Together they complete the day and take 20-30 minutes in total. The phases open in order: the next one does not open until you finish the current one, and the next episode does not open until you finish the current one.
The four phases open at 08:00, 12:00, 16:00 and 20:00 (Türkiye time). Once a phase has opened it never closes again — if you would rather do the 20:00 phase the following morning, it is still sitting there waiting for you. So the times are not deadlines; they are a schedule that sets the rhythm of the day, and when you sit down is up to you.
No lesson is ever lost. Episodes that have already opened stay open and you carry on from where you stopped; before moving you to the next episode the system simply waits for you to finish the unfinished one. Your daily streak is protected too: every 7-day run earns you a snowflake ❄ (up to 3 in reserve) and a missed day is covered by one automatically. If your streak does break anyway, you get a 24-hour window from the moment it broke to win it back.
Core shows you the lessons opening over the next 30 days — the widest view of the three packages. That is a deliberate choice for students who build their own schedule and want to plan around trips and busy weeks in advance.
All four phases together take 20-30 minutes a day. Because the phases open separately you can do them in one sitting or spread them through the day — spreading them out is more effective for retention.
No. Core is a structured learning system built entirely around independent progress; there are no live classes. Messaging a coach and one-to-one mentor sessions are not part of Core: weekly coach messaging comes with Guided, and live one-to-one sessions come with Mentorship.
Yes — the second and fourth phase of every day include microphone drills: the answer you say out loud is graded, and pronunciation is its own lesson type in the curriculum. This is not live conversation with a person; live one-to-one conversation comes with the mentor sessions in the Mentorship package.
Fluency XRAY is an adaptive diagnostic test: it tunes question difficulty to your answers and stops as soon as your level is pinned down accurately enough — for most students that is under 20 minutes. The result is a profile across the four fluency skills, a five-skill radar and a study plan built for you. Before it is published a coach reviews the report; you are then notified by email and it stays in the "Raporlarım" tab of your profile.
Yes. Your plan is built as 28-day monthly flows. At the end of each month everything you did that month is re-scored — which lesson types you struggled with and which you completed — and the next month is built from that. Lesson types you have already worked through rotate out and fresh types from the same skill area take their place, so every month starts on all-new content. You also receive a monthly progress report.
Yes. The curriculum is built from A1 upward and your starting point is the level the Fluency XRAY test measures, so nobody is dropped in somewhere too advanced for them. When you complete a series you are promoted to the next level.
Yes, without limit. You can replay any phase you have finished as often as you like, and there is no daily lesson limit. In the weekly league your best attempt at each phase is the one that counts, so a weaker replay can never pull your points down.
No — same account, same lessons, same progress. You can start on your phone in the morning and carry on at your computer in the evening; your streak, points, medals and reports are identical in both.
You choose how many months you want at checkout (1-12 months; 5% off at 3, 15% off at 6, 40% off at 12) and the whole system is open for that period. There is no auto-renewing subscription — nothing is charged on its own when the period ends. In the transition window afterwards you keep seeing the lessons that had already opened for you.
Full access to the entire curriculum — all four realms and 40+ lesson types — with no daily lesson limit, and the widest view of what is coming. It helps you make English a natural part of everyday life through a regular, sustainable and modern system.
