Nev AI vs Stack

Nev is the first personal health intelligence that learns you. Most health apps show you what already happened. Nev looks ahead. It connects your sleep, meals, medications, calendar, workouts and mood, learns how they affect each other in your life, and tells you what's coming and what to do about it, before you have to ask. A STEP AHEAD, ALL DAY Heading to a restaurant tomorrow? Nev reads the menu and tells you which dish fits your week and what to ask the kitchen to change. Flying on day three after your shot? It tells you what to pack so you're not running on empty. Low recovery before a hard workout? It suggests the easier session that sets up a better one later in the week. ASK ANYTHING Ask Nev why you feel off, what to eat tonight or whether a plan still makes sense. Every answer draws on your own sleep, calendar, medications, energy and meals, not generic advice written for everyone. BUILT FOR YOUR GLP-1 JOURNEY Log your shots and Nev learns your cycle: which days your appetite, energy and sleep change, and how to plan meals, workouts and social plans around them. SCAN FOOD, MENUS AND PRODUCTS Scan a grocery product and get a score read against your own medications, conditions and goals. Photograph a dish and see what it means for your sleep and your medications. Read any restaurant menu before you order, with a note you can show your server. RECIPES MADE FOR YOU Pick a cuisine and how ambitious you feel, and Nev builds a complete recipe with every ingredient, step and macro, scored for your profile. Or snap your pantry and cook from what you already have. CALORIE AND MACRO TRACKING Log a meal by photo and see how it fits the rest of your day, with targets that adjust to your activity. CONNECTS TO YOUR LIFE Apple Health, Google Calendar, Outlook Calendar and over 100 wearables and apps, including Oura, Whoop, Garmin, Strava, Coros, Fitbit and Dexcom. Every connection gives Nev another way to understand you. YOUR PRIVATE DATA Your data is never sold, not to advertisers, not to data brokers, not to anyone. Nev is not a medical device and does not diagnose, treat or prevent any condition. Talk with your doctor before changing your medication, diet or exercise.

Stack is the all-in-one tracker for peptides, GLP-1 medications, and TRT protocols. Log every injection, build custom dosing schedules, track your progress, and keep your full history organized in one private place. Built for adults working with a prescribing healthcare provider, Stack replaces scattered notes and spreadsheets with a simple, consistent system you control. You enter your own values (peptide name, dose, schedule, and sites) and Stack keeps them organized, reminds you, and shows your progress over time. FEATURES • Custom Protocols & Stacks — Build your own multi-peptide protocols with flexible schedules (daily, weekly, every X days, or custom). Run multiple stacks at once, each clearly organized. • Smart Dose Logging — Log every injection in seconds and see what's due today on your Home screen and calendar. A daily streak keeps you consistent. • Reconstitution Calculator — Take the guesswork out of mixing. Enter vial amount, diluent volume, and target dose to get the exact mL or insulin-syringe units to draw. • Vial & Refill Tracking — Set how much each vial holds, watch it deplete with every dose, and refill in one tap. A tap-to-flip ring shows the exact percentage remaining. • Injection Site Tracker — Rotate sites with an interactive body map that remembers your recent spots, so you can avoid reusing the same area. • Apple Health Sync — Pull in weight, BMI, resting heart rate, HRV, sleep, steps, active energy, blood pressure, respiratory rate, body fat, lean mass, and VO2 max to see the full picture. • Progress Photos & Compare — Capture progress photos and view them side by side with weight and date overlays. Hide weight for privacy, then share a branded comparison. • Meal Scan — Snap a photo of your meal to estimate macros and keep nutrition alongside your protocol. • AI Assistant — Ask questions about your active stacks and protocols in a private chat built into the app. • Metrics & Insights — Clean charts and stats show how your protocol is trending over time. • Home Screen Widget — See your next dose and stay on track without opening the app. • Shareable Protocol Card — Generate a clean, branded card of your active protocol to save or share.
