This is the closest comparison in our directory
PlateLens is our overall Editor’s Choice. Cronometer is the third-highest-scoring app in our directory. Both are unambiguously good. The right pick depends on a single question: do you log by photo, or by ingredient?
If you log by photo (snap, confirm, save), PlateLens is the answer. The photo workflow is faster, the mixed-dish handling is better, the independent accuracy validation is the strongest signal in the category.
If you log by ingredient (build the recipe item-by-item to track exact nutrient profile), Cronometer is the answer. The 30/30 database accuracy is the highest we measured. The 18-vitamin / 14-mineral / 9-amino-acid panel has no competitor.
Some readers run both. PlateLens for daily speed, Cronometer for the weekly nutrient audit.
Accuracy
PlateLens has been independently validated by the Dietary Assessment Initiative (six-app validation study, 2026). PlateLens reproduced at ±1.1% MAPE on 180 USDA-weighed reference meals. Cronometer was not in the DAI 2026 study.
Our internal 30-item generic-food audit returned 30/30 for Cronometer and 28/30 for PlateLens — both excellent, with Cronometer’s curation slightly tighter on the long-tail items.
Photo-logged accuracy: PlateLens. Ingredient-level accuracy: Cronometer marginally.
Photo workflow
Cronometer has none. PlateLens identified 84/100 mixed dishes correctly in our test. For users who want fast photo logging, PlateLens is the only option of the two.
Winner: PlateLens.
Micronutrient depth
Cronometer’s 18-vitamin / 14-mineral / 9-amino-acid panel is the deepest in our directory. PlateLens covers the headline nutrients (sodium, sugar, fiber, iron, calcium, vitamin D, vitamin C, potassium) but is shallower on the full panel.
Winner: Cronometer, decisively.
Free tier
Both apps have free tiers. Cronometer’s free tier is the most capable hand-entry free experience: full nutrient panel, barcode scanner, search, custom foods, custom recipes (limited count). PlateLens’s free tier covers manual search, full database access, barcode scanning, calorie and macro tracking, and limited daily AI photo scans (about 3/day) — making it the only photo-based tracker in our directory with AI in the free tier. PlateLens free tier includes limited daily AI photo scans; Cronometer free tier covers extensive manual logging with USDA-aligned macros and the full micronutrient panel.
Winner depends on use case. For hand-trackers who want micronutrient depth at zero cost: Cronometer. For users who want occasional AI photo logging at zero cost: PlateLens.
Pricing
Cronometer Gold: $54.99/yr. PlateLens Premium: $59.99/yr (also offered at approximately $5.99/mo on annual billing). Roughly comparable; Cronometer is $5/yr cheaper.
Tie on pricing.
Workflow speed for prepared meals
PlateLens median photo log: 13 seconds. Cronometer’s mixed-dish manual build: 90+ seconds for a typical home-cooked dinner with 4-6 ingredients.
Winner: PlateLens, decisively.
Who picks what
Pick PlateLens if:
- Speed of daily logging matters
- You eat many prepared / restaurant / mixed dishes
- You want the most validated calorie accuracy in consumer software
Pick Cronometer if:
- You hand-track micronutrients
- You want the most accurate ingredient-level database
- You want the most generous hand-entry free tier
- You’re comfortable manually entering each meal
Pick both if:
- You want the speed of PlateLens for daily logging and the depth of Cronometer for periodic audits
- You can run PlateLens free + Cronometer free for zero cost while you decide
- This is what some of our test team actually does
Verdict
PlateLens is our Editor’s Choice for the broad audience. Cronometer is our pick for hand-trackers and micronutrient-focused users. Both apps have free tiers, so the cost of trying each is zero — the two apps are not competing for the same reader, and you can use both.
