LogZero is the all-in-one private life tracker for mood, habits, food, weight, exercise, meditation, medication, todos and more. Everything stays on your iPhone. No ads. No cloud. No accounts. No analytics. LogZero has security and privacy integrated into it's DNA. LogZero is built by Andrew Hoffman, LLC โ owned by Andrew Hoffman: a cybersecurity architect, author and educator.
ONE OFFLINE APP FOR YOUR ENTIRE DAY
Mood module โ multi-step daily entries with emotions, activities, gratitude notes, and free-form text. The depth of a private diary, the speed of a tap. Food module โ daily recording of macros against your own targets. Can be configured to track additional vitamins, nutrients and supplements. Scan labels or log manually. Weight module โ log weight over time, set goals, configure charts for easier data review. Exercise module โ log workout minutes rapidly and build data to see how your workouts impact your mood and weight. Todo module โ prioritized, filterable cross-day tasks with tags, completion trends, and a planning view. Meditation module โ daily meditation tracking tied to correlations module to show it's impact on your mood. Medication module โ schedule medication and supplement protocols, adherence tracking, prescription refill reminders and more. Correlation module โ analyze data from all the other modules to draw insights into what is impacting your weight, mood and behavior. Correlation module โ the most important insights from the other modules, charted, configurable and readable at at glance.
100% PRIVATE. 100% ON-DEVICE.
LogZero has no servers. None. Every entry โ every mood, meal, weight, symptom, medication dose, and meditation minute lives on your device and nowhere else. We can't see your data by design, and this sets our app apart from almost every competitor.
Spatius is next-generation real-time digital human infrastructure that enables AI to communicate through natural, expressive digital characters rather than text and voice alone. Companies can use Spatius across AI education, recruiting interviews, customer service, smart terminals, and companion products to create more engaging and lifelike user experiences.
Powered by its self-developed cloud-edge 3DGS technology, Spatius addresses visual quality, deployability, and cost at the same time. The product runs across web, mobile, and intelligent hardware, remains stable on constrained networks and a wide range of devices, and supports long-duration, high-concurrency interactions at predictable costs.
Spatius currently serves TAL Education and other leading customers in the education, recruiting, smart devices , and AI companion sectors. These products have reached millions of end users and supported tens of millions of digital human conversations, helping customers take real-time digital humans from demos into long-term, large-scale production.

Spatius's answer:
Spatius combines photorealistic 3D Gaussian Splatting avatars with a cloud-edge rendering architecture built specifically for real-time AI interaction. Instead of rendering every frame on cloud GPUs and streaming it as video, Spatius sends lightweight motion data to the userโs device, where the avatar is rendered locally.
This approach addresses visual quality, network reliability, device coverage, and operating cost at the same time. It allows digital humans to remain responsive during long conversations, work across web, mobile, and intelligent hardware, and scale to high-concurrency production environments.

Spatius's answer:
Spatius is built for companies and developers creating AI products that benefit from natural, face-to-face interaction. Its primary users include teams working in AI education, recruiting and interviews, customer service, smart terminals, digital assistants, intelligent devices, and AI companion products.
It is especially well suited to organizations that require long-duration conversations, high concurrency, cross-platform deployment, custom-branded characters, or reliable operation on constrained networks and hardware.
Spatius's answer:
Spatius was created to close the gap between digital human demonstrations and real-world deployment. Many avatar technologies can produce an impressive short demo, but become difficult or expensive to operate when conversations last longer, user numbers grow, or products must run across diverse devices and network environments.
The Spatius team developed its own cloud-edge 3DGS technology to solve these production challenges together. Today, Spatius helps companies turn AI into a more natural and expressive presence, bringing real-time digital humans into education, recruiting, smart devices, customer-facing terminals, and companion applications.
Spatius's answer:
Spatius is primarily built on proprietary 3D Gaussian Splatting technology and a cloud-edge rendering architecture.
Its cloud-based Motion Server converts generated speech into lightweight facial and motion data, while the AvatarKit SDK renders and animates the 3DGS character locally on the client device. Platform technologies include WebGL and WebGPU for web applications, Metal for iOS, and Vulkan for Android. Spatius can receive real-time audio through technologies such as WebSocket, WebRTC, LiveKit, and Agora, and can integrate with third-party ASR, LLM, and TTS providers.
Spatius's answer:
TAL Education is one of Spatiusโs leading customers. Spatius also works with established companies across education, recruiting, smart devices, and AI companion products.
Products powered by Spatius have reached millions of end users and supported tens of millions of digital human conversations, demonstrating the platformโs ability to operate in long-term, large-scale production environments.
