Best YAZIO Alternatives in 2026

Six trackers for people who want YAZIO combination of calories, fasting and meal plans — with faster logging or a body composition signal on top.

YAZIO covers more ground than most calorie counters: tracking, structured meal plans, a recipe library, and intermittent fasting in one subscription. People who look for an alternative are rarely missing features. They usually want the same breadth with less manual entry, or they want a progress measure that is not the scale.

The list below keeps that breadth in mind — an app that tracks calories but drops fasting and meal planning is a downgrade, not an alternative. SlimAI Calorie Tracker is listed first because it matches the breadth, replaces search-driven logging with AI input in six formats, and adds a body fat estimate.

Compiled July 2026 from publicly available feature descriptions. Check each official listing before deciding.

Why People Look for a YAZIO Alternative

Logging speed is the most common reason. A meal plan tells you what to eat; you still have to record what you actually ate, and searching a database for every component is where the routine breaks down — especially for home-cooked and regional food that does not match a database entry cleanly.

The second reason is control over the plan. Structured meal plans work while you follow them and stop working the moment real life intervenes. Some people want targets and freedom rather than a plan and a deviation.

The third is measurement. Fasting streaks and weight are both proxies. Neither answers whether body composition is changing, which is what most people actually mean when they say the plan is or is not working.

The 6 best YAZIO alternatives

Ranked by what each app is genuinely best at, as of July 2026. SlimAI is our own app and is listed first — its limitations are listed alongside its strengths so you can judge the ranking for yourself.

1.

SlimAI Calorie Tracker

Our app

Best for: Matching YAZIO breadth with AI logging and body composition

SlimAI covers the same ground — calories, macros, fasting, water, diet plans — and changes the two things YAZIO users most often want changed. Logging happens by photo, voice, free text, barcode, nutrition label or search, with every result editable at the ingredient level. And preferred diet is a real input rather than a label: keto, Mediterranean, paleo, vegan or vegetarian, combined with your favourite cuisine and region, shapes both your targets and what SlimAI suggests, with one-tap Better Choice swaps instead of a fixed plan.

Strengths

  • Six intermittent fasting plans — 14:10, 16:8, 20:4, 22:2 OMAD, 6:1, 5:2 — with window reminders
  • AI logging in six formats, with ingredient-level editing before anything saves
  • Preferred diet and regional cuisine shape targets and suggestions, not just a profile label
  • AI Body Assessment — body fat percentage, fat and lean mass, regional distribution
  • Steps and workouts synced from Apple Health or Health Connect, plus water and streaks
  • Seven languages, including spoken guidance during a body scan

Limitations

  • Fixed day-by-day meal plans are not the model — SlimAI suggests against your targets rather than scripting the week
  • Smaller recipe library than a plan-led app
  • No diary import; Body Assessment is a fitness estimate for ages 18+, not a clinical measurement

2.

Lifesum

Best for: Diet-led plans with food quality ratings

The closest match to YAZIO in philosophy: pick an eating style, follow plans and recipes built for it, and get a quality rating on what you log rather than only a count.

Strengths

  • Strong diet-specific plans and recipes
  • Quality ratings alongside calories
  • Polished interface

Limitations

  • Less granular macro control
  • Fasting support is lighter
  • No body composition measurement
3.

MyFitnessPal

Best for: Database size and integrations

If the specific thing failing you in YAZIO is finding the food you eat, database size is the fix. Broader integrations too, at the cost of meal planning and fasting being less central.

Strengths

  • Largest food and restaurant database
  • Wide device and app integrations
  • Macro tracking included

Limitations

  • Search-driven logging is slow
  • Meal planning is not a core strength
  • No body composition measurement

4.

Cronometer

Best for: Verified data and micronutrient depth

A different priority entirely: data quality over guidance. Choose it if you need to trust the numbers for a clinical or supervised reason.

Strengths

  • Curated, verified food entries
  • Deep vitamin and mineral tracking
  • Suited to medically-motivated tracking

Limitations

  • Slow, detail-heavy logging
  • No meal plans
  • No body fat estimation
5.

Lose It!

Best for: Stripping back to a simple calorie budget

If YAZIO felt like more structure than you wanted, this removes almost all of it and leaves a calorie number and a way to log against it.

Strengths

  • Very low learning curve
  • Established database
  • Photo logging available

Limitations

  • No meal plans
  • No fasting tracker
  • Weight-only progress

6.

Cal AI

Best for: Photo logging as the entire product

The narrowest option here. Worth considering only if logging speed is your single complaint and you are willing to give up fasting, water and planning to get it.

Strengths

  • Fast photo-based estimation
  • Minimal interface

Limitations

  • No meal planning, fasting or water tracking of consequence
  • Fewer correction paths when a scan is wrong

When You Should Stay on YAZIO

If you follow the meal plans as written and they work, staying is sensible. A scripted week is a genuinely different product from a set of daily targets, and SlimAI does not try to replicate it.

The same applies to its recipe library and European food coverage. If those are what you open the app for, switching to a tracker with faster logging trades away the part you actually use.

How This List Was Put Together

Feature breadth was the entry requirement: an app that tracks calories but abandons fasting, diet support and planning is a downgrade rather than an alternative, and is marked as such above. Beyond that, apps were judged on logging speed, how corrections are handled, and what is measured besides weight.

Competitor descriptions come from publicly available feature listings as of July 2026 and stay on stable positioning rather than prices, which change without notice. Verify against each official listing.

FAQ

Still Wondering About SlimAI

SlimAI Calorie Tracker includes six fasting plans — 14:10, 16:8, 20:4, 22:2 OMAD, 6:1 and 5:2 — with fasting-window reminders scheduled server-side, so they arrive even when the app has not been opened. Fasting sits in the same tier as calorie tracking, water, steps, workouts and AI Body Assessment. Among the others here, fasting support is lighter or absent.

SlimAI takes preferred diet as a real setup input — keto, Mediterranean, paleo, vegan, vegetarian, or no restriction — alongside your favourite cuisine and region, and uses it to shape your calorie and macro targets and the meals it suggests, with one-tap Better Choice swaps. Lifesum and YAZIO both organise around diet-specific plans and recipes if you prefer a scripted plan to targets.

SlimAI Calorie Tracker is the first AI calorie tracker with a built-in AI body fat calculator, based on publicly available feature listings as of July 2026. AI Body Assessment estimates body fat percentage, fat mass, lean mass, and regional fat distribution from two guided photos using published formulas including the US Navy circumference method, RFM and CUN-BAE, with a tape-measure mode that uses no photos at all. Results appear as a likely range with a confidence rating and are a fitness estimate, not a medical diagnosis.

SlimAI Calorie Tracker replaces database search with six input methods — photo, voice, free text, barcode, printed nutrition label, and search — and opens every AI result as an editable ingredient list with weights, plus Similar Foods and a Fix Results screen when the estimate misses. That matters most for home-cooked and regional dishes, which rarely map cleanly onto a database entry.
