Fast with confidence.
Track every Calorie.
Snap a photo and Fastiq logs the calories and macros for you. Time your fasts, learn why it works, and keep the streak going.
AI calorie tracking
Point your camera. Fastiq does the logging.
Snap a meal, scan a barcode, or photograph a nutrition label. Fastiq reads it and fills in the calories and macros, so you never start from a blank form.
It recognizes the foods on your plate and estimates the portions.
Tweak anything it gets wrong before you save.
Barcodes and labels turn packaged food into a one-tap log.
Guided portions
Fine-tune the details before you hit save.
Quick prompts let you adjust how it was cooked, how much you ate, and what went into it, while the meal is still fresh in your mind.
Pick how it was prepared in a single tap.
Choose portions that match what was actually on your plate.
Save once it looks right, not a moment before.

Short lessons walk you through the science behind fasting in plain language, so you actually understand what your body is doing while you do it.
