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’s adaptive TDEE algorithm recalculates your daily calorie needs based on real-time changes in your weight, workouts, metabolism, and recovery. No more guesswork, just adaptive calorie targets that shift as your body does. - 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.

Not. Work. Data appears and disappears at random, things take forever to load (if they load at all). I completely sympathize with the fact that it’s just one developer doing everything here and that kept me using this app for longer than I would have otherwise, but after a week of infinite refresh/retry/reload, I’m just too frustrated by this app to keep going. **Developer response:** Hi! I'm really sorry to hear about all the issues you've been having. The latest updates resolve most of these issues and there's an announcement going out soon to explain what happened. I hope you come back and give Zolt a chance again, there's a lot of great stuff coming up! ### 3/5 — Ugggh *2026-07-16* I want to love this app. It has everything I want in a fitness/meal tracking app. The problem it only works for me about 25% of the time. It freezes or gets hung up adding items and then I have to force close it. I have a goal to track my meals every day and it’s already a struggle for me because I find it incredibly boring. When I try to use this app and it takes me about 5 minutes before I can get the correct things to load I’m not going to do it. I’m pretty disappointed. Especially since I paid for a year subscription. **Developer response:** Hi! I'm really sorry to hear about all the issues you've been having. The latest updates resolve most of these issues and there's an announcement going out soon to explain what happened. I hope you come back and give Zolt a chance again, there's a lot of great stuff coming up! ### 3/5 — Stopped working *2026-06-11* I really loved this app but now for more than a week all of the features I use do not work AHA level, heart rate zones, cardio load, and adjusted maintenance calories all stoped working. They all get stuck in a state of loading and will sometimes flash until a second until the whole app freezes. Making it useless. **Developer response:** Hi there! I'm sorry you ran into syncing issues! Most of these issues should be fixed in recent updates. ### 5/5 — Data nerd’s dream come true *2026-05-04* Simply put, this app tracks so many variables and creates near real time analyses on how those variables impact things like your TDEE, sleep, recovery, energy levels, etc. Easily worth the money. I haven’t used the in app AI for food tracking yet, but I use a separate AI to help me meal plan and track all my intake, then provide me end of day totals in nutritional label format which I use Zolt’s nutrition label scanning feature to input it as one meal at the end of the day. UI is not always intuitive but workable. Instructions are sparse and it can be buggy sometimes but the developer is *extremely* responsive and seems genuinely enthusiastic about integrating fixes and adding more features. ### 1/5 — Great concept poor execution *2026-03-30, version 2.4.1* The app is buggy beyond belief, it doesn’t import macros stored in Apple health all the time and when it does it’s not accurate. ### 3/5 — The idea is good, but the execution is very buggy and chaotic *2026-02-18, version 2.3.9* Overwhelming UI/UX, excessive information, and most importantly, clunky and buggy ### 5/5 — Intelligent app *2026-01-28* I’ve always been frustrated by apps that give me a static number and expect it to work forever. As someone who values data and real-time progress, I need a tool that’s as adaptive as my metabolism. The app is sleek, smart, and finally gives me the precision I’ve been looking for ### 1/5 — Inaccurate Data *2026-01-24* Other review about inaccurate TDEE is correct, the calorie goals/burned doesn’t line up with the maintenance/weight loss goals. App stops working every few days if you’re lucky, stops working multiple times a day usually, sometimes FOR multiple days **Developer response:** Hey! Sorry you ran into issues with Zolt. We’re always working hard on making the better. If you’re up for it, send me an email at hi@zolthealth.com and I’m happy to help sort this out for you. ### 5/5 — Best fitness tracker *2026-01-07, version 2.3.1* I have used a bunch of trackers and this is the best by far ### 5/5 — Finally found my perfect nutrition tracking app! *2025-12-06* After years of frustrating experiences with MyFitnessPal's cluttered interface and Cal AI's limited features, I switched to Zolt and couldn't be happier. The difference is night and day. What sets Zolt apart is its intuitive design that actually makes tracking enjoyable rather than a chore. The barcode scanner works flawlessly every time, the food database is comprehensive without being overwhelming, and the macro tracking gives me exactly the breakdown I need without burying it under unnecessary metrics. The meal planning feature is a game-changer - something I always felt was missing from other apps. Plus, the insights are genuinely helpful without being preachy or making me feel guilty about my choices. The app loads quickly, syncs seamlessly across devices, and doesn't bombard me with upgrade prompts every five seconds like MFP does. For anyone tired of bloated nutrition apps that prioritize ads over user experience, Zolt is the breath of fresh air you've been waiting for. Worth every penny of the subscription. ## Frequently asked questions about Zolt ### What does Zolt do?
