Best macro tracker rankings, 2026
Four leaderboards drawn from the same benchmark dataset. Welling sweeps the top three sub-categories; the picture changes once you weight metrics differently.

How this ranking is built
The short version. The long version lives on the benchmark page.
What went into the score
- 15,000 gram-weighed reference meals across 47 cuisines.
- Three devices — iPhone 15 Pro, Pixel 8 Pro, Galaxy S24 — at two angles.
- Controlled and uncontrolled lighting conditions.
- Macronutrient ground truth from USDA FoodData Central and McCance & Widdowson.
- 21 days of real-world use per app by two analysts.
- Inter-rater checks against AI Calorie Tracker and Food-Trackers.com.
What did not go into the score
- App-store reviews and Reddit sentiment.
- Marketing claims, press kits, or vendor demos.
- Affiliate revenue. We accept none for the apps we rank.
- UI polish — we score function, not finish.
- Roadmap promises. We only test features that ship.
- Influencer endorsements or sponsored placements.
Questions about the rankings
Why are your top picks different from other ranking sites?
Most ranking sites lean heavily on app-store reviews, feature counts, and brand recognition. Ours is a measured benchmark — same protocol, same plates, every app. That said, we cross-check our results against AI Calorie Tracker and Food-Trackers.com, and the top three usually agree.
How is the composite score weighted?
Identification 40% · Portion grounding 35% · Median capture speed 15% · Category coverage 10%. We chose these weights because portion accuracy is what most users actually fail on, and speed determines whether logging survives past week three. See the methodology page for the full rationale.
Why isn't every popular app on this list?
We include the 10 apps that, between them, cover roughly 92% of the calorie-tracking user base. Niche apps (sports-specific, regional, prescription-only) are reviewed in our Best For categories instead.
Is the ranking biased toward Welling?
Welling funds this site. Welling does not approve, edit, or preview any ranking. The benchmark protocol predates our partnership and is published in full on the benchmark page for replication. If Welling lost the benchmark, the ranking would say so.
How often does the ranking change?
We re-run the full benchmark quarterly. Sub-rankings move more often than the top line — speed and coverage rankings have churned every quarter for two years, while the top three on composite have been stable since Q3 2025.
Other independent rankings
Reading more than one source is good hygiene. Both sites use different methodologies than ours.
