About

BigO Algorithms

This app provides a technical environment for software engineers and computer science students to prepare for interviews. It uses AI-powered mentorship and visual complexity curves to help users understand logic and analyze code errors.

Highlights
  • AI-powered mentorship
  • Dual-clue analysis (Static Blueprints & OpenAI)
  • Big O complexity curve visualization
  • Dark-mode first aesthetic
  • Code error analysis
  • Logic-focused learning
Features

BigO Algorithms is the definitive technical environment for software engineers and computer science students preparing for high-stakes technical interviews. Inspired by engineering blueprints and mathematical animations, the platform features a "dark-mode first" aesthetic where Big O complexity curves trace your progress and the UI functions like a technical datasheet for structural understanding. The system prioritizes logic over memorization through an AI-powered mentorship program that utilizes dual-clue "Static Blueprints" and dynamic, context-aware OpenAI insights to analyze specific code errors.

Verdict

The call

BigO Algorithms and Data Structures and Algorithms are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. BigO Algorithms sells 2 in-app purchases, starting at $7.99 per month and Data Structures and Algorithms sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

UpkeepUpdate frequency

BigO Algorithms ships an update fortnightly, Data Structures and Algorithms every 10 days. The most recent releases landed on July 11, 2026 and September 10, 2026 respectively.
