Lathe Calculator is an efficiency tool designed specifically for CNC turning. Its core goal is to help you calculate parameters faster, generate programs quicker, and reduce errors. Key Features 1. Thread Calculation: Supports metric, imperial, and unified threads, with automatic output of key dimensions and reference G76 programs. 2. Taper Calculation: Covers common scenarios including large/small diameters, taper angles, and Morse tapers. 3. Tolerance & Fit: Quickly check hole/shaft tolerances and determine clearance or interference fits. 4. Arc Tangency Points: Assists with arc transitions and precise cutting point positioning. 5. Macro Programming Assistant: Includes common profiles and machining templates. 6. Additional Utilities: Chamfering, surface speed conversion, weight and material density calculations, and more. Efficiency Features 1. Save and reuse parameters with one tap to reduce repetitive input. 2. Built-in program library for storing and managing commonly used code. 3. Clear and structured results for quick on-site verification and adjustment. Suitable for machinists, CNC programmers, mechanical engineers, and learners in daily use.
Algorithm Heroes

Turn algorithms into weapons. Turn sorting into ultimate moves. Algorithm Heroes is a Roguelike tower-climbing game that blends algorithm learning with card-battle combat. Here, Bubble Sort becomes "Bubble Slash," Quick Sort becomes "Quick Partition," and Binary Search becomes "Binary Arrow" — every algorithm is a battle card, and every swap, comparison, and partition deals real damage to monsters. No memorization required. Understand algorithms naturally through battle. CORE GAMEPLAY: 100-Floor Algorithm Tower 5 chapters, each focused on a core algorithm, with escalating difficulty: · Chapter 1 [Bubble Wilds] — Bubble Sort (FREE) · Chapter 2 [Insertion Forest] — Insertion Sort (FREE) · Chapter 3 [Selection Valley] — Selection Sort · Chapter 4 [Quick Peak] — Quick Sort · Chapter 5 [Merge Sanctum] — Merge Sort A unique Boss guards every 20 floors: Chaos Slime shuffles your battlefield array, Pivot Demon can only be torn apart by divide-and-conquer algorithms, and Merge Dragon wields multiple enrage mechanics... You need to truly understand algorithms to exploit their weaknesses. 8 ALGORITHM CARDS — INFINITE STRATEGY · Sort: Bubble Slash, Insertion Pierce, Selection Strike, Quick Partition, Merge Fusion · Search: Binary Arrow (critical hit), Linear Scan, Hash Locate (ignores armor) Each card can be upgraded to Level 3. Chain same-type cards to trigger Combo multipliers up to 2x damage. Cards have synergy effects — sort first, then search for doubled damage! ROGUELIKE ELEMENTS — EVERY RUN IS DIFFERENT · Normal battles / Elite monsters / Boss fights · Shop: Buy new cards, upgrades, pets · Treasure rooms: Random artifacts · Rest rooms: Recover HP · Random events: Unexpected encounters 6 artifacts with passive bonuses: CPU Booster, Recursion Chip, Stack Overflow, Hash Table... Make every build unique. 6 algorithm pets assist in battle: Bubble Dragon auto-swaps inversions, Binary Fox locks onto target positions, DFS Wolf applies hunt markers... Collect pets and build your ultimate team. 3 ALGORITHM MINI-GAMES — LEARN WHILE YOU PLAY Beyond the tower, enjoy 3 casual algorithm mini-games: · Match — Clear the board with linear search, hash lookup, bubble swap, and sort compress · Snake — Eat numbers in ascending order using binary radar and BFS hints · Blocks — Drop number blocks, sort rows, and trigger clears Each mini-game features unique algorithm mechanics that build your algorithmic thinking naturally. DAILY CHALLENGES & ACHIEVEMENTS · Daily Challenge: Fixed seed, compete with friends · 12 Achievements: From "First Purification" to "Algorithm Hero" · 6 Ranks: Rookie Coder → Algorithm Apprentice → Algorithmist → Architect → Algorithm Master → Algorithm Hero · Shareable stats cards: Show off your tower-climbing record WHO IS IT FOR? · Students: Preparing for CS exams or coding interviews — learn algorithms the fun way · Programmers: Review sorting and searching algorithms while enjoying roguelike deckbuilding · Coding beginners: Zero foundation needed — understand algorithmic thinking through play · Teachers: Demonstrate algorithm execution step-by-step in class THEMES & PERSONALIZATION Multiple programmer color themes: Dracula, Monokai, GitHub Dark, Solarized, One Dark... Pick your favorite code style and take it to the battlefield. FREE TO TRY — PAY WHAT YOU WANT · Chapters 1-2 (40 floors) are completely FREE — includes Bubble Sort and Insertion Sort · Pro unlocks all 100 floors + all algorithms + all themes + pet pack · Or buy chapters, theme packs, or pet packs individually --- From Rookie Coder to Algorithm Hero — your journey starts here. Download Algorithm Heroes and make algorithms your weapon.

Verdict
Lathe Calculator and Algorithm Heroes 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
Both are free to download. Lathe Calculator sells 1 one-off in-app purchase and Algorithm Heroes sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Lathe Calculator ships an update weekly, Algorithm Heroes every 4 days. The most recent releases landed on October 18, 2026 and October 5, 2026 respectively.
