A multi-protocol VPN and proxy client for your own servers. Import subscriptions, control traffic with routing rules, and connect from your Home Screen. IMPORT ONCE, KEEP SERVERS TOGETHER Add a server by scanning its QR code, pasting a link, or entering the details yourself. Import subscriptions to manage multiple nodes in one place. Check server latency before choosing a connection. CHOOSE WHAT GOES THROUGH YOUR PROXY Use Global mode for proxy routing, or Rule mode to choose which traffic connects directly and which uses your proxy. Edit your own rules or import a rule list from a URL. CONNECT FROM YOUR HOME SCREEN See the active server and connection status in the widget, then use its switch to connect or disconnect. On iOS 18 and later, add Spectre VPN to Control Center for another quick way to control your connection. USE THE PROTOCOL YOUR SERVER NEEDS - Shadowsocks and Trojan - VMess and VLESS - Hysteria2 and TUIC - SOCKS and HTTP For advanced setups, use a complete custom sing-box JSON configuration. The app interface supports 14 languages. BRING YOUR OWN SERVER Spectre does not include VPN servers or sell VPN service subscriptions. A compatible server configuration or subscription link is required.

About

Cognitive Physics

This app transforms your device into a truth-seeking instrument by training a personal AI to research alongside you. It guides you to ask better questions, verify claims, and build a permanent knowledge base from your imported materials. Designed for serious workflows, it focuses on observable learning processes rather than just providing answers.

Highlights
  • Train your own AI from scratch
  • Research like a scientist
  • Ask questions with citations
  • Build a permanent knowledge base
  • Multi-agent intelligence
  • Automatic paper generation

Cognitive Physics began as a single, hard-edged question: How do mind and matter belong to the same set of laws? That question led to years of work in Cognitive Physics—and eventually to something tangible. Something you can carry. Something you can use every day. This app runs on Systemic Narrative Integration (SNI), a research technology inspired by how the great minds of physics search for structure inside uncertainty. SNI treats learning as a disciplined process. It measures coherence, tracks uncertainty, and when something is incomplete, it refuses cleanly instead of pretending. The goal is not to sound intelligent—it’s to behave honestly. Cognitive Physics turns your device into a truth-seeking instrument, not a chat toy. Inside the app lives a real AI system designed to grow with you. You don’t just use an assistant—you train your own AI from scratch to research alongside you. It learns from the material you import, adapts based on what you approve or reject, and improves through structured feedback. Rather than dumping answers, it behaves like a teacher—guiding you to ask better questions, build valid requests, verify claims, and develop the habits that lead to real understanding. This is a personal research lab where intelligence isn’t a costume—it’s a process you can observe, shape, and refine. A place where mind and matter meet as measurable structure. A place where your AI doesn’t just talk—it learns the way a serious system should: carefully, transparently, and with you in the loop. What You Can Do with Cognitive Physics Train Your Own AI • Build a personal AI from scratch using your own PDFs, notes, links, and research • Learn through approval/rejection—not blind consumption • Structured feedback improves behavior over time • No forced answers, no hallucinated confidence Research Like a Scientist • Live web, RSS, and paper discovery • Duplicate prevention and source tracking • Date, time, year, and origin preserved for every finding • Automatic evaluation using coherence and entropy signals Ask Questions with Citations • Ask questions directly against your own library • Answers are grounded in retrieved sources • Clickable citations open the exact passage used • If evidence is missing, the app tells you—honestly Build a Permanent Knowledge Base • Import and manage PDFs • Automatic text extraction and semantic search • Quality-based organization (high, medium, low, trash) • Everything stored locally and permanently Multi-Agent Intelligence • Specialized agents for planning, coding, reviewing, testing, and optimizing • Agents coordinate tasks and self-correct • Offline learning from success and failure patterns • Designed for serious workflows, not roleplay Automatic Paper Generation • LaTeX papers generated from accumulated research • Offline diagram and figure creation • Reproducible outputs tied to your source library • Built for real academic and technical use Measure Learning, Not Just Output • Coherence and entropy tracked for every interaction • Structural vs semantic uncertainty separated • Refusal is treated as signal, not failure • Stability and dispersion trends visualized over time Offline-First, Instrument-Grade Design • On-device embeddings and local inference • Works without internet once your library exists • No cloud dependency required • Built with safety, performance, and transparency in mind Cognitive Physics is not about replacing your thinking. It’s about giving you a system that teaches you how to think better, alongside an AI that learns the same way you do.

Verdict

The call

The clearest difference is rating: Cognitive Physics at 5.0 against Spectre VPN's 3.9. Spectre VPN's advantage is ratings volume (251 vs 2) and update cadence (every 2 weeks vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
