Satellite Tracker / Radar vs Delta

Turn your phone into the ultimate AR Sky Guide. Identify lights in the night sky instantly. Whether tracking the International Space Station (ISS), watching a Starlink train, or identifying Constellations, Satellite Tracker provides professional-grade data with a stunning interface. NEW: AR STARGAZING MODE Stop guessing where to look. We've expanded our Augmented Reality view to include the stars! Identify Stars & Constellations: Align your phone to see constellation lines and star names drawn over the real sky. Satellite AR: Spot the ISS, Hubble, and thousands of satellites with precise zenith alignment. Unified View: See how satellites move through the constellations in real-time. NEW: AUGMENTED REALITY (AR) MODE Stop guessing where to look. Activate the AR Sky View and point your camera at the sky. The app overlays the exact position of satellites, the ISS, and celestial objects directly on your screen. Align the zenith arrow and spot objects in seconds. CORE FEATURES: Live Sky Radar & 3D Globe Visualize Earth and its orbiters like never before. Switch between a 2D Radar Scope for polar plotting or a stunning 3D Interactive Globe to see satellite trajectories relative to the Earth's day/night line. ISS & Starlink Tracker Get precise Pass Predictions. We calculate flyovers specifically for your location using the latest SGP4 propagation data. ISS Spotter: Know exactly when the Space Station will rise and set. Starlink Trains: Track the famous "string of pearls" satellite constellations. Notify Me: Set alerts for the next 2 hours or next 6 hours so you never miss a visible pass. Massive Database (NORAD/TLE) Access a catalog of over 12,000+ objects. From active weather satellites to space junk and classified bodies. Search: Find objects by Common Name or NORAD ID. Classify: Color-coded filters for LEO, MEO, GEO, and HEO orbits. Live Telemetry: View real-time altitude, velocity, range, and doppler shift. Power User Tools Offline Mode: Heading to a dark-sky preserve? Predictions work without internet access. Device Optimization: Adjustable "Satellite Limit" to ensure smooth performance on any device. Download Satellite Tracker today and join the community of sky-watchers. Never ask "What was that light?" again.

You read about AI every morning. Newsletters, threads, release notes. By Friday, almost none of it is left. The habit is not the problem. The format is. Reading something once is the least effective way to learn anything, and an entire content economy sits on top of it. Delta is the other half. Thousands of short lessons on what actually changed, each ending in a question you have to answer. Being asked is what makes it stick; reading never did. Ninety seconds, usable in a queue. WHAT A CARD LOOKS LIKE Two or three paragraphs, then a question. Not a quiz question. Predict the output. Spot the bug in the IAM policy. Pick the cheaper option and say why. Name the tradeoff the benchmark table is hiding. Then the explanation, which is the part that matters, written by someone who has shipped the thing rather than read about it. Every card links to the source it was written from. We never reproduce it. NINE TOPICS Foundations and modeling. Attention variants, scaling laws, fine-tuning, evaluation methodology, reading a benchmark table honestly. Generative AI. Reasoning models, context handling, structured output, sampling. Agentic AI. Tool use, MCP, planning, memory, and the failure modes only agents have: loops, runaway cost, silent partial failure. AI engineering and inference. KV cache, quantization, batching, routing, what a token actually costs you in production. Data and retrieval. RAG and how it fails, chunking, reranking, drift. AI security. Prompt injection direct and indirect, exfiltration through tools, MCP supply chain, sandboxing, least privilege, the OWASP LLM Top 10. Responsible AI and governance. Bias measurement, interpretability that survives an audit, the EU AI Act by risk tier, NIST AI RMF, ISO 42001, model documentation and audit trails. Always framed as what you have to build, never as policy commentary. Enterprise AI architecture. Landing zones, multi-tenancy, identity for agents acting for users, build versus buy. AI operations and reliability. Monitoring nondeterministic systems, evaluation in production, regression testing prompts, incident response when the model is the incident. This is for AI Engineers. Almost nobody develops anything for the engineer who has to get an agent through a security review, satisfy an auditor, and keep it inside an SLA. IT REMEMBERS WHAT YOU FORGOT A scheduler runs underneath, tracking what you got right, what you got wrong, and how long you took. A correct answer that took twelve seconds is not the same as one that took two. You never see any of it. There is no review queue, no due count, no deck to clear. Cards you are about to forget simply reappear in the feed, indistinguishable from new ones. BUILT FOR PEOPLE WHO ALREADY KNOW THINGS Delta assumes you know what a transformer is. It will not explain backpropagation. It is for practitioners with a few years of shipping behind them who want to know what changed this month and why it matters, not what a neural network is. NO ADS, EVER The entire premise is that this is the calm alternative to a feed that monetises your attention. There is no advertising identifier anywhere in the app and there never will be. Nothing about you is sold or shared. FREE AND PAID A free set in every topic, so you can see the whole range before deciding. The subscription opens the rest: thousands of cards across all nine topics, new material as the field moves, and a scheduler that brings back what you got wrong before you forget it. Delta Pro is $4.99 per month or $49.99 per year. Payment is charged to your Apple ID. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the period ends, and you can manage or cancel in your Apple ID settings at any time.
