Cognitive Physics vs Hermex
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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.
- 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.

Hermex is a native iPhone and iPad client for your self-hosted Hermes agent. It connects directly to your Hermes host. Existing Hermes Web UI servers keep working as legacy. Open existing sessions, start conversations, and follow streamed responses, tools, and reasoning as they arrive. Queue, steer, or stop an active run. Review file edits as diffs, browse workspace files, send photos and files, and dictate messages. Switch between Bots and Sessions, manage Kanban boards and Cards, browse Tasks, Skills, Memory, and Usage, and choose models, Profiles, and reasoning settings. Move to Hermes brings a Web UI server’s chats, drafts, and notifications over to your Hermes host. Live Activities keep working runs visible on the Lock Screen and Dynamic Island. Optional notifications let you know when work finishes or needs your attention. The share extension stages content from other apps for you to review and send. Agent execution happens on your configured server, not on the iPhone. Your server owns your conversations, tools, and workspace. Recent sessions and messages may be cached locally for read-only offline viewing; clear that cache from Settings. There is no Hermex-hosted agent backend, tracking, or analytics service. Optional push notifications use an open-source, self-hostable relay. Message previews are encrypted on your Hermes host and decrypted on your iPhone; the relay handles device tokens, notification metadata, and ciphertext, never message text, server URLs, or Hermes server credentials. Push is off until enabled. Hermex has no in-app account creation or in-app purchases. You need your own reachable Hermes server. Not affiliated with Nous Research.

Verdict
The clearest difference is ratings volume: Hermex at 197 against Cognitive Physics's 2. Hermex also leads on update cadence (every 2 weeks vs monthly) and chart position (#25 vs unranked). Cognitive Physics's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.
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. Neither carries in-app purchases, so what you see is what you pay.
Cognitive Physics holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Hermex has 197 ratings behind it against 2, so its average is the more settled of the two.
Cognitive Physics ships an update monthly, Hermex every 2 weeks. The most recent releases landed on October 31, 2026 and November 1, 2026 respectively.
