Bevel transforms your biometric data into actionable health advice, generated by persistent memory AI.
This is the health app that Apple or Google should have designed. Connected watch, scale, continuous blood glucose sensor… Biometric data accumulates silently every day on our iPhones, carefully collected, rarely used. Bevel breaks this logic: the application aggregates all health data stored locally in Apple Health and subjects it to cutting-edge generative AI models, to extract truly actionable insights on a daily basis. No more inert graphs to interpret alone, a real analysis system that works for you. We used it for a month. Here’s what we take away.
Make individuals responsible for their own health
Launched in 2024 by Gray Nguyen and Aditya Agarwal, the application was designed to give individuals responsibility for their own health again. “We want to revalorize the idea that you are the person best placed to understand your own body. This is not about rejecting modern medicine, quite the contrary. But we believe that you should be in control of your health, with doctors and technology to guide you and not to make decisions for you,” explain the founders. The ambition is clear: a simple, effective application, delivering actionable and truly personalized advice.
Concretely, Bevel connects to Apple Health and continuously ingests all of your biometric data (heart rate, heart rate variability, SpO2, sleep, etc.) to submit it to a generative AI model. The result is organized around three fundamental metrics: effort, recovery and sleep. Three variables in communicating vessels, which the AI analyzes jointly rather than in silos. This is precisely where Bevel differs from everything that has existed until now: the model does not just display curves. It reasons on your data, detects correlations, and generates surgical recommendations. Tired this morning? The AI explains precisely why (example: too intense a sports session the day before). Planning a workout? It calculates your optimal performance window. Looking to maximize your recovery? The AI tells you the ideal bedtime, calculated on your own biological data.
Bevel Intelligence, the real asset
But the real asset of Bevel lies in its AI assistant, “Bevel Intelligence”. Presented in the form of a simple chatbot, it is directly connected to all of your biometric data and answers you on any sporting, medical, pharmaceutical or nutritional question, without hiding behind excessive safeguards (like ChatGPT or Gemini). You can submit your medical examination results, the contents of your meals to log your caloric and nutrient intake, or even directly connect your continuous blood glucose sensors to refine its diagnoses and recommendations.
What makes Bevel Intelligence really different is its persistent memory architecture, an operation close to OpenClaw type agents. The assistant records all of your conversations and your personal information to build an increasingly precise profile over the weeks. In practice, Bevel knows that Monday and Friday I work remotely and that these are my sports days. It reminds me of my sessions and advises me on the exact intensity to adopt by analyzing my state of fitness in real time, to avoid overtraining. Before a trip abroad, he remembered a previous conversation about this trip and took the initiative, the day before, to recommend that I reduce the volume of my session to limit residual fatigue during the trip. This is exactly what we expect from a good AI agent: that it responds not only correctly, but precisely, based on the user’s real context.
More surprising, and potentially divisive, Bevel also advised me on taking treatment. For example, melatonin to manage jet lag, taking into account my sleep data and the context of my trip. The assistant even responds when asked about choosing an analgesic for a headache. Bevel is, in a way, your personal doctor available 24 hours a day. In any case, this is how I use it on a daily basis. And so far, in a month of intensive testing, no hallucinations or notable slippages have appeared.
The future of connected health?
Bevel says it never shares your medical data with third parties, but the risk exists. Your health data, stored locally on your iPhone, is sent to the cloud to be processed by the app’s AI engine, which relies on proprietary US LLMs whose identities are not disclosed. The risk of leakage to third parties is real. But is the game worth it? At 17.99 euros per month or 59.99 euros per year with the Bevel Pro plan, the only one to integrate artificial intelligence, the application offers a personal medical assistant available day and night and trained on your own biological data. For anyone looking to seriously optimize their health and fitness on a daily basis, this is a real gain. For serious medical problems, the doctor obviously remains essential. But for daily monitoring, prevention and optimization of lifestyle habits, Bevel is today without equivalent on iOS.
Still, the application has a good chance of being partially copied by Apple during a next major update of iOS. Bevel will nevertheless probably retain its advantage in the fluidity and freedom of tone of its AI. Because it is difficult to imagine Apple authorizing, in Europe at least, its users to question an AI model on strictly medical questions. Ultimately, Bevel provides a concrete overview of health in 2030: continuous biometric monitoring, interpreted by an increasingly precise AI, which does not replace the doctor but seriously begins to resemble him.
