Cronometer vs YAZIO

Cronometer is the more natural starting point for detailed nutrient questions. YAZIO is organized around food tracking, fasting, and recipes. Both have paid photo logging, and Cronometer also offers fasting and coaching.

About this comparison. Fuel publishes this page and competes with these apps. This September 8, 2026 update compares documented features, tier access, and practical use cases. It is not a new controlled speed, accuracy, or reliability test. Recommendations are qualitative; an older review score is not a measured head-to-head result.

01Choose nutrient investigation or a fasting-centered routine

Choose Cronometer for nutrient detail and inspectable food sources. Choose YAZIO for a food diary organized around fasting, recipes, and routine.

02What each app currently offers

Cronometer is the stronger starting point when you want to inspect vitamins, minerals, and the source behind a food entry. Its current listing documents free barcode scanning, an Apple Watch app, and Gold features including photo/voice logging, fasting, and Crono Coach. A branded label entry can still lack nutrients that were never measured or supplied; a long nutrient panel is not a guarantee that every field is known.

YAZIO combines food tracking, fasting, and recipes. Its Pro documentation includes AI photo tracking, and its current product page describes manual and barcode options alongside it. Check the Pro offer for your account before comparing costs; a discounted annual subscription and a monthly plan are different commitments.

03Fasting is no longer an exclusive difference

Cronometer Gold has a fasting tracker and Crono Coach. YAZIO combines fasting plans with its diary and recipe tools. The real comparison is how easily the routine fits your day.

Try starting, editing, and ending a fast, then logging the meal that ends it. Compare the available schedule and reminders in the actual tier you intend to use.

04Choose food sources before trusting the chart

Cronometer offers detailed generic-food data alongside branded entries. A label-only entry may leave several nutrient fields unknown. For either app, compare a scanned product with its label and confirm the serving weight.

Claims about phantom entries or failed history sync require dated, attributable evidence. They are not a sound basis for a categorical current verdict without a reproducible case.

05A useful two-day trial

Use one meal you cook and one meal you buy repeatedly. In Cronometer, inspect the nutrient detail you care about. In YAZIO, evaluate how the diary, recipe, and fasting routine fit together.

Pick the app whose information changes your next meal, not the one with the most dashboard elements.

06Compare the full cost before choosing

Cronometer: US Gold: $10.99/month or $59.99/year; free basic tier. Official features and terms.

YAZIO: Free basic tier; Pro price and term shown in regional checkout. Official features and terms.

A monthly equivalent for an annual plan is still an upfront annual charge. Where a public fixed price is unavailable, compare the offers shown on the same day in the same country rather than treating an old promotional price as universal.

07Make the choice from your next ordinary week

Start with the app that solves the problem named above, then log a normal workday and a training or weekend day. Check portions, reuse a meal, and inspect the feedback before the trial ends.

If your priority is Apple Watch-based targets and a daily coaching workflow, see how Fuel works. That is a separate product choice; the case for either app here should stand on its own.
