Atomic Fast

Overview / Description

Atomic Fast is a fasting and mindful eating tracker for iOS and Android that covers the full habit loop. Log fasting windows, record meals using AI (describe or photograph what you ate and it fills in the nutritional details), track daily water intake, and get plain-language metabolic progress summaries. The AI meal logging cuts down on manual entry friction, which is where most fasting apps lose users. Daily insights surface patterns across your eating windows, hydration, and energy — without requiring a nutrition degree to interpret them. Built for people doing intermittent fasting who want more than a countdown timer but less complexity than a full diet-tracking platform.

Used For
