A food diary, calorie tracker and fasting timer in one calm place. Log meals, follow your macros, and keep food, water and your weight trend together on iPhone and Apple Watch. LOG FOOD YOUR WAY Take a meal photo for an AI estimate of calories and macros, describe what you ate, scan a barcode, search for food, or enter a meal yourself. Review portions and nutrition estimates before saving. Photo analysis is limited to 10 meal photos per day. FOLLOW CALORIES AND MACROS See your daily food totals, including protein, carbohydrates and fat. Keep a food diary, review meal history, and follow calorie and weight trends over time. TRACK INTERMITTENT FASTING Choose a fasting preset or set your own schedule. Follow your timer, review past fasts, and check progress from your iPhone or Apple Watch. KEEP WATER IN VIEW Log water, set a daily goal and choose reminders. Home Screen and Lock Screen widgets let you add water without opening the app. SEE SLEEP AND RECOVERY ALONGSIDE FOOD Connect Apple Health to see sleep, recovery and activity readings alongside your nutrition. Google Health integration is also available in beta. Choose your leading source; readings show where their data came from. Available insights depend on the health data you connect. ON YOUR WRIST Use the Apple Watch app to check your day, follow a fast and track supported activities. Widgets keep useful information close at hand. SUBSCRIPTION REQUIRED Zen Lean is free to download. An active subscription or eligible trial is required to use the app after onboarding. Monthly and yearly plans are available.

Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel your subscription in your Apple account settings. YOUR ACCOUNT AND DATA Meals, weight, water and fasting records sync through your account.

Once you pass your goal, the timer counts up instead of showing a negative time. • Today and Your foods stay within reach while you scroll through Meals. • Activity brings your daily totals and timeline together, with workout types in a row you can swipe. • Edit your profile or open Settings directly from the top of Profile. ### 1.2.0 — 2026-09-28 Write to the Founder. A new row in Settings sends a message straight to the person who built the app, with a reply within 24 hours. The app may also ask once in a while, never more than once a week. Settings is now a page with an area for each topic: account, backup, health sources, morning check-in, reminders, data export, analytics and about. The morning check-in on Insights is a one-line banner with your last forty mornings drawn as a hairline. Fixed a crash a few seconds after opening the app while meal photos were being tidied up in the background. ### 1.1.2 — 2026-09-19 Updated our App Store listing to describe food logging, calorie and macro tracking, fasting, and subscription access more clearly. App features are unchanged. ### 1.1.1 — 2026-09-18 We have refreshed our App Store description and screenshots to make it easier to explore fasting, food logging, sleep and activity tracking. This update does not change how the app works. ## More apps by ZenProducts Technologies Pvt.
