The Binary Game vs Subnet Driller

Convert 8-bit binary to decimal like a pro. Perfect for network engineers mastering subnets, IPs, and bitwise ops. Dive into The Binary Game, the brain trainer designed for network engineers, IT pros, and anyone hooked on binary-decimal conversions. Challenge yourself with lightning-fast 8-bit binary challenges—input the decimal equivalent and watch your skills grow. Key Features: 10-Question Rounds Each round delivers 10 random 8-bit binary numbers (00000000 to 11111111). Enter the decimal value (0-255) via quick-tap numpad or keyboard. Visualize your progress with graphs showing accuracy trends, fastest rounds, streak counters, and improvement over time. Practice the exact 8-bit conversions used in subnet masks, VLANs, port numbers, and hex-to-binary workflows. No fluff—just pure, practical training to level up your networking game. Endless Replayability Unlimited rounds with procedural generation. Play in short bursts during commutes or deep sessions to build muscle memory. Dark mode, haptics, and satisfying feedback make it irresistible. Whether you're prepping for CCNA, debugging networks, or just love the thrill of binary, The Binary Game turns practice into power. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

An offline subnetting quiz for CCNA, Network+, and other certification candidates. Questions are randomly generated, answers are deterministic, and every calculation is hand-verified. It drills the "magic number" / block-size method I memorized before my own exams: built for speed and repetition. Features: - Built-in block-size ("magic number") reference, one tap away - Five question types: network address, broadcast, first and last usable host, usable host count - Multiple choice or written answers - or a mix of both - SESSION and TOTAL counters, plus a per-type accuracy breakdown - Optional daily practice reminder - Fully offline - no accounts, ads, tracking, or subscriptions - Shamelessly vibe coded using Fable 5; the subnet math lives in its own package and is hand-verified for accuracy About me: I'm a working network engineer and active CCNA, living in Arizona, USA. Questions, feedback, or bug reports? I read and reply to every email personally.
