for everyone who quit LeetCode on day 6
You do the coding.
We handle the motivation.
DSAMotivator sits on top of LeetCode and turns daily practice into a streak you refuse to break — with freezes for bad days, a pattern map that fills in as you solve, and worked solutions you can watch run one step at a time.

Watch the algorithm run
Most write-ups hand you finished code and leave you to work backwards. An algorithm clicks the moment you see why a step is safe to take — so ours animate it, one move at a time, with the reason underneath.
Searching for 24. If it exists at all, it's somewhere in this range.
That's not an illustration someone drew. It's a recording of our Binary Search implementation actually executing — which is why it can never quietly disagree with the code it explains.
Built on behavioral science, not willpower
Four mechanisms, backed by four decades of published research — then battle-tested on hundreds of millions of people by the apps you already can't stop opening. We just pointed the same machinery at your DSA prep. No dark patterns — you'd see through them anyway.
Streaks that hurt to lose
Loss aversion is roughly twice as strong as the pull of reward. A streak turns your consistency into property — and freezes (earned every 7 days) insure it against one bad day.
Proven at scale: Duolingo calls streaks their single most effective retention mechanic.
XP with surprise bonuses
Every solve pays 10–75 XP with a random 1–1.5× multiplier. Variable-ratio rewards produce the most persistent behavior ever measured in a lab.
The schedule Skinner documented in 1957 — and every feed you doomscroll runs on.
A map that begs to be finished
20 DSA patterns as a skill tree that lights up as you solve. Incomplete structures occupy the mind until they're closed.
The Zeigarnik effect (1927) — and why your GitHub graph's grey squares bother you.
Your plan, not our nagging
On day 1 you write one sentence: “after dinner, 9pm, 1 problem.” Our only reminder is that sentence, sent back to you at the moment you chose.
Implementation intentions: medium-to-large effect across 94 studies (d ≈ 0.65).
You will forget the problem you solved today
Not might — will. Recognising a solution is far weaker knowledge than reconstructing one, and a problem you nailed in March is gone by June. Sheets can't fix that, because a list has no idea when you last saw anything.
So every problem you solve becomes a card that comes back — and the schedule above is the one this app actually runs, read straight from the code. Each review is earned by genuinely re-solving the problem on LeetCode, not by ticking a box, which is why solving your favourite problem twice in a week can't inflate the ladder.
The decline is Ebbinghaus's exponential curve (1885), not a measurement of our users. The review days are ours.
Three steps. Two minutes.
Connect LeetCode
Username only — we read public stats and import your history. Your existing progress lights up the map on day 1.
Commit to a tiny plan
“After dinner, 9pm, 1 problem.” Small enough to survive your worst day. That's the point.
Solve on LeetCode, as usual
We detect accepted submissions automatically. Streak extends, XP lands, map fills. You just keep showing up.
A sheet is a list. This is a schedule.
Every sheet tells you whatto solve. Neither tells you what to solve today, or what you've started forgetting.
A plan that reacts to reality
Give us your interview date and an honest daily pace. We spread the work across the weeks you actually have — and recompress it when life happens. If the date genuinely doesn't fit, we say so and tell you the pace that would, instead of handing you a plan that quietly drops half the syllabus.
Revision timed to when you'd forget
Problems come back on an expanding schedule — 1, 3, 7, 21, 60 days — and drop back down if you leave one too long. Nothing to tick off: re-solve it on LeetCode and we notice. A problem you solved in March is gone by June unless something brings it back.
Nobody gets hired on DSA alone
You clear the algorithms round and then someone asks you to normalize a schema or write a window function. Same problem as DSA — you learned it once, months ago — so it runs on the same schedule.
Core CS
DBMS, operating systems, networks and OOP — 311 questions across 4 subjects, written to survive the follow-up rather than to define the term.

Bring your own sheet. Or your own course.
Following NeetCode 150? Striver's SDE Sheet? Blind 75? A paid course you're halfway through? A random Notion doc your senior sent you? Doesn't matter. Every accepted LeetCode submission extends your streak, earns XP, and fills your Pattern Map — no matter where the problem came from.
We're not trying to replace the course you bought. Courses fail for one reason, and it isn't content — it's that you stopped opening them in week three. This is the layer that gets you back tomorrow.

“Let's grind this together” dies on day four
You and a friend pick a sheet. You both mean it. Then neither of you can see whether the other actually solved anything, so you both quietly stop — and neither of you is embarrassed, because nobody noticed. That was never a discipline problem. Nobody was watching.

Seven days each, in each person's own timezone.
Up to eight people. One row each.
- Nobody can bluff.Every square is an accepted LeetCode submission we read ourselves. There is no “yeah I did some yesterday” here.
- It's not a leaderboard. No ranking, no points table, no XP contest. Whoever still owes today floats to the top, because the gap is the useful information — not the podium.
- You can poke someone. Once a day, at most, however many of you press it. Enough to be a nudge, not enough to be a group chat you mute.
- And nothing else crosses over. Not your email, not your LeetCode handle, not which problems you solved. Leave, and you vanish from their screen the same second.

Fair questions
Do you need my LeetCode password?+
Never. You give us your username, we read your public stats, and you prove ownership by pasting a one-time code into your profile summary. That's the whole handshake.
What counts as keeping my streak?+
One accepted LeetCode submission per day, in your timezone. That's deliberately tiny — the worst day of your week still fits one Easy problem.
What if I miss a day?+
You earn a streak freeze for every 7-day run (you can hold 2). A missed day consumes a freeze automatically instead of killing the streak. One bad Tuesday shouldn't erase a month.
Is there a free trial?+
No, and that's deliberate. Paying at all — however little — is itself a commitment device: a plan you've put money behind gets followed, and free plans get abandoned in week two. Since that only works if it's fair, every plan carries a full refund within 7 days, no questions asked. It's a trial where the money is real enough to matter and you still can't lose.
Do you actually explain the problems, or just track them?+
Both. Every solution we've written comes with a visualization of the algorithm running step by step — and that animation is a recording of the code on the page actually executing, so it can never drift out of sync with the solution it illustrates. The write-ups are free and public; what you pay for is the system that decides which one you should be reading today.
Why would I pay for motivation?+
You're not paying for motivation, you're paying for consistency infrastructure: streak accounting that's timezone-correct, freezes, reminders built from your own plan, and a map of what you've actually mastered. The DSA itself stays free on LeetCode.
Can I do this with friends?+
Yes — that's a squad. Up to eight of you, one row each, showing whether you solved today and how your last seven days went. It's read from LeetCode, so nobody can claim a day they didn't do. It isn't a leaderboard and it isn't a chat: whoever still owes today sits at the top, and that's the whole feature. Your friends see a name you choose and nothing else — not your email, not your LeetCode username, not which problems you solved.
Can I cancel?+
Anytime, in two clicks. Your XP and Pattern Map history stay yours — if you come back, you don't restart from zero.
₹19$5$3is the cheapest commitment device you'll ever buy.
Free plans get abandoned in week two — you already know this, because you've done it. Put a real number behind the plan and by day 30 you'll have a streak you refuse to break. Full refund within 7 days if we're wrong.
