Build momentum you can keep.
Zerith turns your goals, schedule, fitness history, and optional health data into a practical 12-week program. Each day starts with one clear next move—not another dashboard to decode.
WHEN LIFE HAPPENS, THE PLAN ADAPTS
Missed a workout? Your week is not broken. Move it, shorten it, do the smallest useful version now, or rest intentionally. Zerith helps you recover momentum without shame or all-or-nothing streaks.
YOUR PERSONAL 12-WEEK PROGRAM
• A weekly training and nutrition plan shaped around your goals
• One prioritized action for today
• Workout details with gym and home options
• Weekly check-ins that adapt the next plan with your approval
• Clear progress toward the outcomes that matter to you
A COACHING TEAM IN YOUR POCKET
Max helps with training, scheduling, and follow-through. Mei explains nutrition and health patterns in practical language. Ask questions, adjust your plan, and understand why each recommendation matters.
APPLE HEALTH, MADE ACTIONABLE
With your permission, Zerith can read steps, weight, workouts, and heart-rate data from Apple Health. Your progress updates automatically while your detailed health history remains on your device.
PRACTICAL NUTRITION
Log a meal with a photo or short description, see an editable protein and fiber estimate, and get meal ideas that fit today’s plan and what you have on hand.
LAB TRENDS WITHOUT THE ALARM
Import a report or add results manually. Zerith presents trends calmly, distinguishes non-fasting results, and connects measurements to the habits your program is building.
PRIVATE BY DESIGN
No account is required. Zerith stores your profile and detailed history on your iPhone. Coaching requests use an anonymous installation identity, are encrypted in transit, and are never used for advertising.
SEVEN DAYS FREE, THEN $5.99 A MONTH
Your first 7 days are free. After the free trial, membership is $5.99 per month, charged to your Apple Account and renewing automatically each month until you cancel. Cancel at least 24 hours before the free trial ends to avoid being charged; manage or cancel any time in your Apple Account settings. No ads. Your history remains available to view, export, or delete either way.
Zerith provides general health and fitness guidance, not diagnosis or treatment. Estimates may be inaccurate. Consult a qualified healthcare professional before making medical decisions or starting a new exercise or nutrition program.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
**What’s New (1.5):**
• Max and Mei now notice more, and say so. Good news gets a message: weight trending down, an inch off your waist, Fuel weeks kept, a lab marker back in range, and your Zone 2 target going up.
• When things slip, the coach reaches out kindly: a welcome back after a quiet stretch, a note when a week runs under your usual, and a clean slate when this week can't be kept. Never guilt, always one small next step.
• Max adjusts to what you tell him. Sessions that keep feeling hard or easy, a day that keeps getting squeezed, or workouts you keep shortening each get one suggestion for next week. Say "Try it" or "Not now".
• If your weight is trending up and losing weight is your goal, Mei suggests one simple swap for a meal you eat often.
• Tap "Not now" often and the coaches back off. Turning down Reaching out does the same.
• A forgotten workout you confirm now earns its full Zone 2 minutes.
• Plans keep generating after you leave the app, and a dropped connection no longer loses a finished plan.
• Bug fixes and reliability improvements.
