8 Strong Cronometer Alternatives for 2025: Nutrition Trackers Compared

Alternatives at a Glance

*Price reflects new Premium+ tier as of April 2025.

How We Tested

• Data fidelity: We compared logged values for salmon, almonds and broccoli against USDA SR Legacy to gauge database accuracy.
• Workflow speed: Time‑to‑log was measured for a three‑item lunch using barcode, search or photo AI.
• Meal‑plan generation: Where applicable, we generated a seven‑day plan and checked macro compliance, prep minutes and grocery export quality.
• Cross‑domain integration: Wearable imports (weight, HRV, CGM) and export pathways (CSV, Apple Health) were verified.
• Pricing transparency: We flagged impossible‑to‑cancel trials and hidden upsells.

1. Centenary Day — Best for All‑In‑One Automation

Centenary Day isn’t just a tracker; it’s your health operating system. A five‑minute quiz builds a personalised Weekly Routine—sleep, workouts, meditation—then pipes that timeline into a linear‑programming Nutrition Planner. The solver balances calories, macros and fibre while minimising prep minutes across the household. Protein Shake blocks auto‑appear if your day falls short on protein, and shopping lists group perishables vs. shelf‑stable items.

Micronutrient coverage stands at 45 key nutrients—less than Cronometer’s 82 but enough for most users, including iron, magnesium, potassium and omega‑3. Guideline stars score behaviours like “Omega‑3 ≥1 g/d” or “Added sugar <25 g,” turning grey to orange to green as streaks form.

Pros

• Automatic meal plans integrated with workouts and sleep blocks.
• Household scaling and Instacart export (road‑map Q4 2025).
• Guideline feedback beyond nutrition (Zone‑2 cardio, fasting window, digital curfew).
• Transparent pricing: free tier usable; Pro $9/mo.

Cons

• Micronutrient panel not as deep as Cronometer.
• No public food database editing—recipes vetted centrally.

2. MyFitnessPal — Largest Crowd‑Sourced Database

With 13 million foods, MFP remains unbeaten for obscure global snacks. Barcode scanning is fast, Meal Scan uses AI to parse plate photos, and integration with Strava, Garmin and Apple Health means your exercise net calories adjust automatically. But feature drift has fractured tiers: Barcode Scan and Net‑Carbs now hide behind Premium+, and ads saturate the free version.

Nutrient tracking tops out at 25 vitamins and minerals—fine for macros, weak for micronutrient enthusiasts. There’s no automated meal planning, so you’ll spend time assembling menus or juggle extra services like Eat This Much.

Pros

• Massive food database—excellent for international travellers.
• Voice‑logging and photo AI (Premium).
• Vibrant community forums and recipe posts.

Cons

• Premium+ hits $19.99/mo; ads if you don’t pay.
• Nutrient depth limited.
• No grocery or meal‑plan automation.

3. MacroFactor — Dynamic Calorie Engine for Athletes

MacroFactor’s USP is its coaching algorithm. Weekly weight entries and diary adherence feed a Bayesian model estimating true maintenance calories. Targets shift up or down automatically to keep you on track, whether you’re cutting, recomping or bulking. Strength athletes appreciate recipe weight‑tracking (adjust ingredient weights post‑cook) and a power‑user food database with macro overrides.

Side note: MacroFactor’s founders—Greg Nuckols and Eric Helms—publish peer‑reviewed research, so algorithm transparency beats many rivals.

Pros

• Adaptive macro targets—perfect for metabolism shifts.
• Evidence‑based blog and podcast integration.
• CSV export and Apple Shortcuts for automation.

Cons

• No free tier; 7‑day trial only.
• No meal‑plan generator or grocery workflow.
• Micronutrient panel limited.

4. MyNetDiary Premium — Diabetic‑Friendly Insights

MyNetDiary shines for blood‑sugar management. CGM sync with Dexcom and Abbott Libre overlays meal‑time glycemic impact charts. Carb counts flag net carbs, and there’s a robust prescription meds log including insulin bolus factors. The database claims 1.4 million verified foods—verified meaning staff check label accuracy, cutting duplicates common in MFP.

A Fast & Easy meal planner suggests breakfasts, lunches and dinners matching your macro goals; tap one to add to diary and auto‑create a shopping list (US retailers only for now).

Pros

• Top‑notch diabetes tools and CGM overlays.
• Verified food entries reduce barcode frustration.
• Meal suggestions with grocery list.

Cons

• Interface less slick than YAZIO or Lifesum.
• Some features (CGM sync) cost extra.

5. Nutritionix Track — Fast Logging for US Chains

Ever eat Subway, Chipotle or Chick‑fil‑A? Nutritionix has first‑party data feeds from 800+ US chains, ensuring macro accuracy. The Track app focuses on speed: tap a restaurant, customize toppings, log. A voice chatbot (Track Bot) lets you text meals via iMessage—powerful when your hands are sauce‑covered.

Micros are sparse (17 nutrients), but for US travellers who snack at chains, accuracy beats depth.

Pros

• Lightning‑fast chain‑restaurant logging.
• Voice and SMS logging.
• Cheap premium ($4.99/mo).

Cons

• No meal planning.
• US‑centric database.
• Limited micros.

6. YAZIO PRO — Budget Tracking with Fasting Coach

German‑born YAZIO keeps prices low: $39.99/year often discounted to $23 on holiday sales. PRO unlocks an intermittent‑fasting timer, seasonal recipe packs, and weekly meal‑plan suggestions with grocery lists you can export to PDF. The interface is colourful, with streak flames and avatar levels for gamification.

Micronutrients hit 30 vitamins/minerals—solid middle ground. Quick‑add macros are handy during buffets where barcode scan fails.

Pros

• Cheapest annual cost among ad‑free trackers.
• Built‑in fasting and water coach.
• Offline logging for data‑roaming globetrotters.

Cons

• Smaller community support in English.
• Exercise sync limited (no Garmin).

7. MyMacros+ — One‑Time Purchase for Bodybuilders

A $2.99 one‑time fee (iOS) buys unlimited macro logging. Designed by a pro bodybuilder, the app emphasises grams of protein, carbs and fat per meal and daily total. A Workout+ subscription adds lifting logs and rest‑timer integration with Apple Watch for $1.99/mo—still cheaper than most.

Micronutrients are nearly absent; recipe builder lacks sharing, and barcode database skews US. But if you just need fast macro hits without recurring fees, MyMacros+ is unbeatable.

Pros

• One‑time cost.
• Blazing‑fast macro logging.
• Custom macro goals per meal—great for pre/post‑workout nutrition.

Cons

• Limited food quality control.
• No micros or meal‑plan automation.

8. NutraCheck — Best for UK Accuracy

UK barcodes often fail in US‑centric apps. NutraCheck solves this with a dedicated UK label‑scanning team, updating 3000 new items weekly. Premium at £4.49/mo removes ads, unlocks water and five‑a‑day fruit/veg badges, and adds a weekly meal planner with exportable shopping list for Tesco, Sainsbury’s, Ocado.

Pros

• Top UK database accuracy.
• Fruit/veg and saturated‑fat gauges.
• Integrated weekly planner.

Cons

• Only available in UK app stores.
• Limited wearable integrations (Apple/Google only).

Takeaway

Cronometer excels at micronutrient depth, but 2025’s health stack demands more: automated meal plans, adaptive macros, grocery exports, wearable and CGM insights. Whether you need holistic life automation (Centenary Day), coach‑level adaptive targets (MacroFactor), or UK‑specific barcode precision (NutraCheck), there’s a tracker tailored to your exact needs. Test a couple of free tiers, examine your biggest friction point—and commit to the one that makes logging effortless rather than another chore.
