03//How it works

From scattered tabs to one dashboard

No setup fee, no seat limit, no locked tier. Four steps and you're prepping with everything tracked.

01

Connect your profiles

Sync LeetCode, Codeforces, CodeChef, GeeksforGeeks, HackerRank and GitHub in a minute. Every stat updates itself from there.

02

Pick your sheet

Striver, Love Babbar, Blind 75, NeetCode 150 — or skip straight to company-wise or role-wise, whatever the next round needs.

03

Track it problem by problem

Every checkbox, streak and topic breakdown saves to your account and follows you across every device you open it on.

04

Walk in prepared

System design, core CS, aptitude, and HR questions — waiting for the rounds sheets don't cover.

05//Stories

Students who
cracked it with crackalgo

The company-wise sheet was the whole game. Three of the problems I revised the night before showed up almost verbatim in my loop.

Aarav Sharma

SDE Intern · Amazon

Role-wise questions meant I stopped grinding things my round would never ask. React, Node and a bit of design — exactly what came up.

Divya Menon

SDE Intern · Adobe

Coming from a non-CS background, the notes broke every fundamental down into something I could actually hold in my head.

Rahul Verma

Analyst · Accenture

The HR sheet is underrated. Sixty-odd questions sorted by type, with sample answers — I walked into the round with nothing left to improvise.

Fatima Khan

SDE 1 · Cognizant

One coding round, one technical, done. The graph and BFS/DFS set covered it end to end.

Arjun Nair

SDE Intern · Swiggy

I spent most of my prep in the SQL sheet — window functions and CTEs were exactly what they drilled me on.
