Zolt: TDEE & Macro Coach

Zolt is an adaptive body coach to help you lose fat, build muscle, and maintain healthy habits.

Zolt helps you reach your goal body with intelligent, personalized coaching. Whether you're cutting, bulking, or maintaining, Zolt adapts to your body every day using your own data and not just static formulas. We use an adaptive TDEE algorithm (also known as dynamic TDEE or dynamic expenditure) to help make sure you always are on track to reach your weight goals.

Start with your goal. Zolt handles the rest: tracking, adapting, and coaching you toward it.

Adaptive TDEE & Macros That Evolve With Your Body

- Zolt estimates maintenance calories from your logged calorie intake and body-weight trends, then uses that estimate to adjust targets for your goal. Apple Watch calories do not drive the learned TDEE estimate or its updates. You can use adaptive TDEE without a Watch.

- Your macro goals also adjust based on your progress, protein preferences, and dietary focus. Everything is personalized, yet effortless.

Personalized Calorie Goals for Every Phase
- Zolt supports your current phase — cutting, bulking, or maintaining — and evolves with you over time. Weekly and daily check-ins help you stay consistent while your nutrition plan flexes as your weight, training, and goals shift.

- Zolt doesn't just set targets, it guides you through every plateau, push, or reset.

Smart Food Logging with Barcode, AI, and Recipes
- Log meals with speed using AI-powered food search, barcode scanning, and custom recipe creation. Track full macros and micros, not just calories, and set flexible RDA goals based on your preferences.

- Zolt turns food tracking into a seamless, personalized experience that supports your goal — not one more chore to manage.

Activity Goals That Adjust to Your Energy & Training Load

- No one-size-fits-all goals here. Zolt creates daily movement targets that respond to your actual recovery, energy, and recent workouts. Whether it’s a normal day, a recovery day, or a performance push, your goals adapt accordingly.

- Cardio load metrics like TSB, ATL, and CTL help guide intensity over time. You train smarter, not harder.

Recovery and Sleep Insights from Apple Watch Data

- Zolt pulls from your Apple Watch to deliver real recovery insights — not just pretty graphs. Your sleep, HRV, resting heart rate, and SpO₂ are translated into recovery scores and readiness ratings.

- You’ll get actionable tips to improve sleep quality and reduce stress, and a habit journal to help identify what’s boosting or breaking your recovery.

Health Journeys and Habit Goals That Align With Your Big Picture

- Zolt lets you go beyond weight to build your ideal lifestyle. Group goals into “Journeys” like longevity, performance, or energy and track habits like steps, cardio, sleep, hydration, and more.

Zolt is more than a health tracker. It's a body coach that evolves with you.


Smarter guidance. Clearer goals. Better results.
