LogicSystem puts a true AI agent in your hands—not just a chatbot, but a capable digital worker that plans, executes, and delivers, all inside a fully isolated, privacy-first ecosystem. YOUR OWN AGENTIC AI Create a personal AI agent and give it real work. Logic System agents don't stop at answers—they take action: • Browse the live web and research topics in depth • Write, run, and debug code in a real execution environment • Create documents, reports, and files you can actually use • Break big jobs into steps and work through them autonomously • Delegate long-running tasks to background sub-agents and check back when they're done PERSISTENT MEMORY & PROACTIVE WORK Your agent remembers your projects, preferences, and past conversations across sessions—no re-explaining yourself every time. Schedule recurring tasks, set reminders, and let it keep working while you're away. Results are waiting when you get back. DEDICATED, ISOLATED COMPUTE Every agent runs in its own isolated environment. Your queries, code, and files never touch third-party servers, are never used to train models, and are never shared with anyone. No data mining, no external exposure, no exceptions. NO HIDDEN CONTROL We control and manage powerful open-weight models ourselves—including advanced reasoning models that think through hard problems step by step. You're never subject to the data-mining practices of large tech corporations or governments. ALL-IN-ONE CAPABILITY Drafting policy, debugging code, researching markets, generating images, brainstorming your next product—your agent is a researcher, coder, analyst, and advisor in one platform. MINIMAL SETUP Start working in minutes. No servers to configure, no complex deployments—just instant, reliable AI agents. Logic System is engineered for professionals who demand both cutting-edge agentic capability and uncompromising data security. Download now and put your first AI agent to work.

Verdict

The call

The clearest difference is in-app purchases: LogicSystem at none against dB Meter's 1. LogicSystem also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). dB Meter's advantage is update cadence (every 4 days vs every 2 weeks). On price and ads there is nothing between them.
