Best YAZIO Alternatives in 2026

Eight trackers for people who want YAZIO combination of calories, fasting and meal plans — with faster logging, a lower price, or a body composition signal on top. Updated 3 September 2026.

Short answer

The best YAZIO alternatives are SlimAI Calorie Tracker for AI logging and a body fat estimate, Lifesum for diet-led plans, MyFitnessPal for database size, Cronometer for nutrient depth, MacroFactor for adaptive targets, and Lose It! for simplicity. Few people leave YAZIO short of features; they leave wanting the same coverage with less time spent logging.

Summarize this page with:ChatGPTClaudePerplexityGoogle AI Mode

YAZIO covers more ground than most calorie counters: tracking, structured meal plans, a 2,900-recipe library, and intermittent fasting in one subscription — and a free tier that keeps barcode scanning and the fasting timer, which most rivals paywall. People who look for an alternative are rarely missing features. They usually want the same breadth with less manual entry, a lower Pro price, or 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, and is marked as such. SlimAI Calorie Tracker is listed first because it matches the breadth, replaces search-driven logging with AI input in several formats, adds a body fat estimate, and compares your fasting, training, hydration and body-scan data against each other rather than leaving each one in its own tab.

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. YAZIO now describes itself as an AI calorie tracker, but its listing does not say which AI features are free, and the logging model it describes is still search and barcode.

The second reason is price. YAZIO Pro is sold in annual, semi-annual and quarterly terms, and its App Store listing shows several discounted variants of the same subscription, so the figure you are offered depends on the promotion served to you. Our YAZIO review quotes the current listing prices with a date and a source. Several alternatives below cost less per year, and one has no paid tier at all for the features most people use.

The third 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 fourth 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. Nothing in YAZIO estimates body fat.

Free-tier and paid-tier entries reflect each app’s own App Store listing on 3 September 2026. Prices are deliberately not quoted here — most listings show several in-app purchase prices for the same subscription and the one you see depends on the offer served; our YAZIO review carries the dated figures. SlimAI is our own app; its barcode scanner entry says "see listing" because the free-tier feature list on the store is the source of truth for what is included.

The 8 best YAZIO alternatives

Ranked by what each app is genuinely best at, as of September 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 or search, with one AI photo scan a day free with no time limit, and every result editable at the ingredient level before it saves. 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 by photo, voice, text or search, with ingredient-level editing before anything saves
  • One AI photo scan a day on the free tier, permanently — not a trial
  • Preferred diet and regional cuisine shape targets and suggestions, not just a profile label
  • Health Patterns compares your fasting days against your own non-fasting days, training against rest, and lean mass across two body scans
  • AI Coach reads the week into a trajectory, a cause and one action, with a free written report every Monday
  • AI Body Assessment — body fat percentage, fat and lean mass, regional distribution
  • Pro at $29.99 a year — under $3 a month — below YAZIO's listed annual Pro price (dated figure in our YAZIO review)

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 — and barcode scanning moved behind Premium in 2022, which YAZIO still includes free.

Strengths

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

Limitations

  • Search-driven logging is slow
  • Barcode scanner and meal scan are Premium
  • No meal planning focus, 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. Its free tier is the most capable in the category for nutrient tracking; Gold pricing, with a date and source, is in our Cronometer review.

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
Compare SlimAI with Cronometer point by point
5.

MacroFactor

Best for: Adaptive calorie targets from your own data

MacroFactor calculates your energy expenditure from your own logged intake and weight trend, then adjusts your targets each week. It is the most quantitative option here and is aimed at people who already understand macro periodisation. Nothing plan-led, nothing fasting-led — it is a targets app, and a rigorous one.

Strengths

  • Adaptive expenditure calculation from your own data
  • Weekly target adjustments without manual recalculation
  • Strong macro-first design for coached training

Limitations

  • No free tier at all
  • Assumes real familiarity with macro tracking
  • No fasting, no meal plans, no body composition
Compare SlimAI with MacroFactor point by point
6.

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
Compare SlimAI with Lose It! point by point
7.

Noom

Best for: A behaviour-change course with tracking attached

Noom sells daily psychology lessons, colour-coded food categories and human coaching, with a food diary underneath. Worth considering only if what you liked about YAZIO was being told what to do — Noom does that more, at a coaching-programme price.

Strengths

  • Structured daily curriculum
  • Human coaching available
  • Colour-coded food guidance

Limitations

  • Priced as a programme, not a tracker
  • Logging is search-driven
  • No fasting timer, no body composition measurement
Compare SlimAI with Noom point by point
8.

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. Its listing states that scanning results require a subscription, so there is no functional free tier.

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
  • Scanning results require a subscription

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, its European food coverage, and its free tier. If you count calories and fast without paying and never hit a wall, YAZIO is giving you one of the most complete free offers in the category and there is no reason to leave it.

What YAZIO Costs, and What the Alternatives Cost

YAZIO is free to download and, per its own App Store listing, keeps the calorie diary, macro analysis, barcode scanner, food ratings, water and step tracking and the fasting timer on the free tier. Pro adds custom meal plans, in-depth food analysis, Fitbit and Garmin sync, mood and symptom tracking, long-term trends and removes ads.

YAZIO Pro is sold in 12-month, semi-annual and 3-month terms. As of 3 September 2026 its App Store in-app purchase list shows several discounted variants of the same subscription beside the standard ones, which means the price you are offered depends on the promotion served to you. The dated figures, with a link to the listing, are in our YAZIO review; treat any single number — there or anywhere else — as a snapshot.

For comparison, SlimAI Pro is $29.99 a year — under $3 a month — with a permanent free tier that includes one AI photo scan a day, the fasting timer, water, workouts, adaptive calorie goals and the Monday AI Coach report. Cronometer Gold is a modest annual subscription with a strong free tier underneath it. MacroFactor has no free tier. MyFitnessPal, Lifesum, Lose It! and Cal AI each show several prices for the same subscription on their listings, which is why the table above names the tier rather than quoting one.

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, what the free tier actually includes, and what is measured besides weight.

Competitor descriptions, free-tier lists and prices come from each app’s public App Store listing as read on 3 September 2026. Prices in this category change without notice and often differ by offer; verify against the official listing on your own device.

What the research says before you switch

Independent findings, not ours

The app you switch to matters less than whether you keep logging in it, and every tracker in this category — YAZIO and SlimAI included — inherits the same database problem.

Across 90 adults tracking food in an app for eight weeks, the people who completed the study logged on 70.2% of days and lost 2.19% of body weight, against 1.54% for the sample as a whole, which logged on about half of days. Frequency of logging explained 6.8% of the variance in weight change.

Source: Payne JE, Turk MT, Kalarchian MA, Pellegrini CA (2022). Adherence to mobile-app-based dietary self-monitoring — impact on weight loss in adults. Obesity Science & Practice 8(3):279–288. doi:10.1002/osp4.566

A meta-analysis of 14 validation studies covering 12 dietary-record apps found every app underestimated energy intake against its reference method, pooled at −202 kcal/day (95% CI −319 to −85). Where the app and the reference used the same food-composition table, the gap fell to −57 kcal/day (95% CI −116 to 2), so most of the error came from the database rather than the app.

FAQ

Still Wondering About SlimAI

Is there a free YAZIO alternative?

Several, but read what "free" includes. Cronometer’s free tier is the most capable for nutrient tracking. SlimAI Calorie Tracker’s free tier includes one AI photo scan a day with no time limit, unlimited text and database logging, six fasting plans, water and workout tracking, adaptive calorie goals and a written AI Coach report every Monday. MyFitnessPal and Lose It! are free for the diary but put barcode and photo scanning behind their paid tiers. YAZIO itself keeps barcode scanning and fasting free, which is a higher bar than most.

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, Lifesum’s fasting support is lighter and the rest do not include a fasting timer.

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. None of the other apps on this list estimate body fat.

YAZIO Pro is sold annually, semi-annually and quarterly, and its App Store listing shows discounted variants of the same subscription, so the price depends on the offer you are served; our YAZIO review quotes the current figures with a date. SlimAI Pro is $29.99 a year with a permanent free tier. Cronometer Gold is an annual subscription with a strong free tier. MacroFactor has no free tier. The others show multiple prices for the same product on their listings, so check the figure on your own screen.

SlimAI Calorie Tracker replaces database search with photo, voice, free text and search input, 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. Cal AI is faster still for a single photo, at the cost of everything else on the list.
