Laso: Own Your Health. Every Bit of It. Stop collecting data. Start using it. You’ve likely been wearing a smartwatch for years. You have thousands of heart rate samples, sleep stages, and step counts sitting in a cloud somewhere. But what has it actually changed? Most health apps are built to keep you scrolling, not to keep you healthy. They give you "participation trophies" for basic movement but leave you with zero clarity on how you actually feel. Laso fixes this. We unify data from your Apple Watch, Garmin, Oura, or Fitbit into a single, high-performance dashboard. We don’t build features to keep you in the app; we build tools to get you back to your life with total physiological clarity. WHAT LASO DOES FOR YOU 1. Identify the "Why": Why was your recovery low? Why is your heart rate trending up? Laso’s on-device AI connects the dots between your sleep, activity, and vitals to find the patterns you’re missing. 2. Performance, Not Just Fitness: Whether you’re training for a marathon or just navigating a high-stress work week, Laso gives you the "Ready to Push" or "Need to Rest" signal based on your actual data, not a generic goal. 3. Real-Time Biofeedback: Use Live Activities to turn a moment of high stress into a moment of calm. Watch your vitals respond in real-time as you engage in guided breathwork designed to recalibrate your nervous system. 4. Your Health at a Glance: With beautifully designed Home and Lock Screen widgets, your most important metrics are always visible. No need to dig through five menus just to see your recovery score. 5. Siri Shortcuts: Use your voice to log health events or check your status hands-free. Laso integrates deeply into your daily workflow. THE PRIVACY MANIFESTO 1. In an era where health data is a commodity, Laso is a fortress. We believe your medical history is yours alone. 2. Your Phone is the Server: All analysis happens locally via on-device machine learning. 3. Zero-Knowledge System: We don’t see your data, we don’t store it, and we definitely don’t sell it. 4. No Ads. No Tracking: No data brokers, no third-party scripts, and no "anonymous" sharing. WHO IS THIS FOR? 1. Laso is for the proactive. It’s for the person who is tired of "average" and wants to understand their unique physiological baseline. It’s for those who demand high-fidelity insights without sacrificing a shred of privacy. 2. Stop guessing. Start knowing. Download Laso today and turn your data into momentum. Explore the mission at https://www.lasohealth.fit Why this version works: 1. Direct Critique: It calls out the "participation trophy" culture of fitness apps, which resonates with serious users. 2. Feature Integration: It mentions Live Activities, Widgets, and Siri Shortcuts—these are "premium" features that make the app feel like a high-end tool. 3. Technical Authority: Explaining that "Your Phone is the Server" is a powerful way to describe on-device processing to a tech-savvy audience. 4. Space Utilisation: This sits at around 2,200 characters total, giving you a meaty, impressive description that feels substantial but remains very easy to scan.

Your dream physique is built on muscle failure. We turn your Apple Watch into an automatic workout tracker. It starts your sets, counts your reps, names the exercise and measures how close each set came to muscle failure. No buttons, no phone, no logging between sets. FULLY AUTOMATIC ◆ Starts sets: Riven sees when a set starts and when it ends. Nothing to start or stop. ◆ Counts reps: every rep is counted from your wrist as you do it. ◆ Names exercises: 100+ exercises supported, and the most common lifts are recognized on their own, including bench press, squat, curls, rows, pulldowns and lateral raises. ◆ Measures muscle failure: the moment you rack the weight, your set gets a score from 0 to 100 for how close you came to muscle failure. ◆ Scores every muscle: see which muscle groups reached muscle failure in each workout. ◆ Syncs with Apple Health: sets, reps, exercises and scores are saved on their own. SHARE YOUR WORKOUTS ◆ Post to the feed: share any workout, with the muscles you took to muscle failure, and get kudos and comments from other lifters. ◆ Weekly league: see where your average muscle failure score ranks against lifters worldwide, and join challenges. ◆ Your choice: make your profile private any time, and report or block anyone. WHAT IS MUSCLE FAILURE? It's the rep you can't finish. Muscle grows when you train close to it, but most lifters stop a few reps short and never know it. Riven tells you after every set, in colors you can read at a glance: Red: stopped short Orange: working Yellow: near muscle failure Green: muscle failure HOW IT MEASURES MUSCLE FAILURE Your Apple Watch reads your wrist's motion 100 times a second. As a muscle tires, your reps slow down. Riven measures that slowdown, called velocity loss, which is the best-studied sign of fatigue in strength training. Heart rate is saved to your log, but it isn't part of the score. NOTHING EXTRA No camera, no barbell clip, no chest strap. Works with barbells, dumbbells, cables and machines, using the watch you already wear. REQUIREMENTS Apple Watch Series 6 or later (watchOS 10+), paired with an iPhone on iOS 17 or later. Detection, counting and scoring run on the watch. The iPhone app handles setup, history and plans. PRIVACY Motion is processed on your devices. No ads. No third-party trackers. Full policy at riven.fit/privacy. PLANS ◆ Free: 1 workout per week, forever. ◆ Unlimited: no weekly limit, monthly or yearly. Prices are shown in the app for your region.
