## What is LeetGrind?

LeetGrind is the focused way to master the LeetCode and NeetCode 150, the essential set of data structures and algorithm problems every software engineer should know.

FLASHCARDS & SOLUTIONS
Every problem is a flashcard. Tap to flip between the problem statement and a detailed breakdown: approach, algorithm steps, time/space complexity, and full code solutions in Python and Java.

QUIZ YOURSELF
Each card includes a built-in quiz. Answer, get instant feedback showing the correct answer, and track your accuracy over time. Mark problems as Done or flag them for Review Later.

SPACED REVIEW
Build real retention. The app tracks which problems you've solved, which ones need review, and how many attempts each took. Come back to your flagged problems and keep drilling until they stick.

STREAK TRACKING
Stay consistent. The dashboard shows your current streak, best streak, daily activity heatmap, and progress ring, all at a glance. Set a daily goal and watch yourself improve.

SMART REMINDERS
Set notifications that remind you hourly, every 2–4 hours, or at custom times you pick. Choose which days of the week, and configure your own start/end hours. Never break your streak.

ALL 150 PROBLEMS ORGANIZED
Problems are grouped by category: Arrays & Hashing, Two Pointers, Sliding Window, Stack, Binary Search, Linked List, Trees, Tries, Heap / Priority Queue, Backtracking, Graphs, Dynamic Programming, Greedy, Intervals, Math & Geometry, and Bit Manipulation.

PRIVACY FIRST
All your data stays on your device. No accounts, no tracking, no analytics. Just you and the grind.

ONE-TIME PURCHASE
Unlock everything for $1.99. No subscriptions, no recurring charges, no ads. All future updates included.
