Fasting and meal tracking together
Track fasting windows and food in the same app so meal timing, fast progress, and eating goals stay connected instead of living in separate tools.
Atomic Fast
Atomic Fast is an intermittent fasting and mindful eating app for iOS and Android that combines meal logging, fasting tracking, and Apple Health-based insights. It helps users see how meals, fasts, and health signals affect one another in a single workflow.
Overview
Atomic Fast is an intermittent fasting and mindful eating app that combines fasting tracking, meal logging, and health-data analysis in one system. The homepage positions it as a single place to monitor what you eat, how you fast, and how those behaviors affect each other.
The app emphasizes AI-assisted meal logging, with support for photos, typed descriptions, barcode scans, nutrition labels, gallery uploads, and saved meals. It also presents fasting education and metabolic phase guidance, then layers in Apple Health-based signals such as sleep, heart rate, activity, and HRV to generate correlations and timing advice.
The product is available on iOS and Android, with download links for the App Store and Google Play. The pricing page currently returns a 404 in the collected source content, so no pricing or plan structure is available from the site material reviewed here.
Features
Multi-method AI meal logging
Log meals in under 10 seconds using photos, typed descriptions, barcode scans, nutrition label scans, gallery uploads, or saved meals.
Nutrition tracking and meal insights
See calorie, macro, water, and nutrient tracking alongside meal-specific AI analysis for each log.
Meal-to-fast impact analysis
View how a meal affects your fast, including digestion completion, time back to fat burning, and fasting timeline updates when you log during a fast.
Health-data analysis
Use Apple Health data such as sleep, heart rate, activity, HRV, daylight exposure, and respiratory rate to generate fasting insights and correlations.
Adaptive smart nudges
Receive phase-based and diet-aware nudges, including hydration tips, metabolic phase milestones, and timing suggestions based on what you ate.
Use cases
Managing fasting windows
People who fast regularly can track fast duration, see fasting phase milestones, and log meals from the fasting view so the timeline updates automatically when they break a fast.
Logging meals quickly
Users who want faster food logging can capture a plate with a photo, type a short description, or scan a barcode instead of searching through a database entry by entry.
Reviewing health correlations
People trying to understand the relationship between diet and recovery can review sleep, heart rate, HRV, activity, and daylight exposure alongside fasting behavior.
Testing meal timing choices
Anyone experimenting with meal timing can compare how eating earlier or later changes digestion, fat-burning timing, and other fasting outcomes.
Following adaptive prompts
Users who prefer guided behavior changes can act on adaptive nudges such as hydration tips, timing suggestions, and metabolic phase alerts based on their own data.
