Vivara vs SYSTEM JJ

Vivara - the only tracker where your nutrition and your training actually talk to each other. Most apps give you a flat daily calorie number. But your body doesn't work on a fixed budget, a long walk, a heavy leg day, or a quiet rest day all change what you need. Vivara is built around one core idea: your macros should move with you. - Dynamic Goals - our signature engine This is what makes Vivara different. Our Dynamic Goals algorithm continuously connects three things most apps treat separately: • Your baseline - calculated from real exercise science (Mifflin–St Jeor BMR, weight trend, goal rate) • Your movement - steps, active calories, and workouts pulled live from Apple Health • Your goal - cut, maintain, bulk, or perform Every day, Vivara compares what you actually did against your rolling 14-day baseline and gently adjusts your calorie and macro targets - dampened and capped, so a single big day never tips you into "earned calorie" binging or under-fueling. Open the Today screen and you'll see exactly why your number changed: base kcal, activity adjustment, goal adjustment, all laid out. It's not magic. It's an algorithm built on published exercise physiology, the closest thing to a coach watching your week unfold in real time. - Workout calories you can actually trust Vivara uses MET-based estimates for cardio and strength, cross-checked with heart rate via the Keytel formula, conservative on purpose. No inflated numbers, just honest data feeding your daily targets. - The Today dashboard A single screen for your macros, calories, workouts, steps, weight progress, and a daily score (0–100) that tells you how you're really doing, at a glance. - Logging that gets out of your way • Snap a meal photo for a quick macro estimate • Build a personal food library for one-tap logging • Create custom recipes with full nutrition breakdowns • Plan your week ahead with the meal planner • Scan barcodes for packaged foods - Workouts, built around you Browse hundreds of exercises, log strength sessions set-by-set with rest timers, track cardio with live heart rate, follow your session on your iPhone lock screen and Apple Watch with Live Activities. Completed workouts sync back to Apple Health automatically. - Friends, feed, and friendly challenges Add friends, share meals and workouts on the activity feed, react and comment, and join step, protein, and workout challenges. Accountability that actually keeps you going. - Streaks, badges, and seasons Weekly badges, lifetime milestones, and 12-week seasons make the long game fun.

Vivara is built by just three people - one developer, one designer, and one branding & marketing lead. After many months of work and a long closed beta with users we love, we're finally opening Vivara to the world. This is day one, not the finish line. We have a long roadmap and the app will keep getting better. If something feels off, missing, or just almost right, tell us. Real feedback is how Vivara gets shaped. If you enjoy the app and want to support us, going Premium is the single biggest thing you can do. It directly funds the small team behind Vivara, keeps us motivated to keep shipping, and unlocks a bigger weekly limit on our AI-powered features.
