The 7 apps, ranked
Nutrola
94/100Fastest logging in the category — photo-AI capture in ~10 seconds, ad-free, $2.50/mo or $29.99/yr.
Logging consistency is the variable that most predicts weight-loss outcome in the published research (Patel 2019). Nutrola's photo-AI capture removes the two friction sources that drive logging abandonment — search-and-pick (replaced by camera capture) and portion-size mental math (replaced by AI portion estimation, anchored to an RD-verified database). Per-meal logging drops to ~10 seconds. Ad-free at every tier; $2.50/month or $29.99/year Premium for unlimited use. For users who have struggled with consistency on search-based trackers, this is the right answer.
Lose It!
90/100Cleanest mainstream search-based UI, budget-remaining UX, half the price of MyFitnessPal.
Lose It! is the mainstream search-based weight-loss tracker we recommend most often. Cleanest UI in the search-based category, calorie-budget framing that's beginner-friendly, Snap It photo logging included, $39.99/year Premium. For the median first-time tracker user who prefers search-based to photo-AI, this is the right pick.
MacroFactor
92/100Adapts your calorie target weekly based on your actual weight trend.
MacroFactor's algorithmic TDEE estimator closes the 'I'm not losing weight, but I'm hitting my target' feedback loop. The app adjusts targets weekly based on your real data. For users who plateau and don't want to manually recalculate, this is structurally better than any static-target tracker. $71.99/year.
Cronometer
90/100The most accurate underlying data — verified database and full micronutrient tracking.
For users who want their calorie totals to be as accurate as the consumer category allows in a search-based workflow, Cronometer's verified-by-default database is the right answer. Free tier covers full calorie + macro tracking; Gold at $54.99/year for biometric trends.
MyFitnessPal
82/100Best US chain restaurant database for users who eat out frequently.
If your eating pattern includes US chain restaurants frequently, MyFitnessPal's database depth on chain menus is best-in-class. Ad-supported free tier or ~$79.99/year Premium. The price-per-feature is high relative to Lose It!, but the database advantage is real for the chain-restaurant use case.
FatSecret
78/100Fully-free weight-loss tracking — calorie, macro, barcode without paywalls.
For users who refuse subscriptions, FatSecret's free tier handles weight-loss tracking. Ad-supported, but no core features are paywalled. Premium at $2.99/month only removes ads.
Yazio
77/100Best tracker for users combining weight loss with IF.
Yazio's integrated intermittent-fasting tracker is the best in the category for users running 16:8, 18:6, 5:2, or OMAD protocols alongside calorie tracking. Premium $39.99/year. Strong European packaged-goods coverage.

What Matters for Weight Loss Tracking
The honest framing from the published research: weight loss via calorie tracking is driven by logging consistency, not by app choice or app accuracy. A user who logs 6 days/week for 6 months will out-perform a user who logs 7 days/week for 3 weeks — across any reasonable tracker. The right app is the one you’ll actually open daily.
The mechanism that drives logging consistency is friction per meal. A tracker that takes 30 seconds per meal will be abandoned faster than a tracker that takes 10 seconds per meal. This is why we put photo-AI tracking (~10 seconds per meal) at the top of this ranking — not because the kcal output is dramatically more accurate, but because faster logging produces more consistent logging produces better weight-loss outcomes.
That said, the apps in this ranking are also picked for accuracy (better database), adaptive coaching (when you plateau), and feature fit (chains, IF, free). Pick by which combination matters most to you.
The Ranking
Nutrola is the lowest-friction tracker in the category. Photo-AI capture takes ~10 seconds per meal. RD-verified database check on every AI scan gives it the strongest accuracy architecture in the photo-AI lane. Ad-free at every tier; Premium $2.50/month or $29.99/year. For users who have struggled with sustained logging on search-based trackers, Nutrola is the right answer.
Lose It! is the best mainstream search-based weight-loss tracker. Cleanest UI, budget-remaining framing that’s beginner-friendly, Snap It photo logging included, $39.99/year Premium. For the median first-time tracker user who prefers search-based.
MacroFactor is the right pick for users who plateau and don’t want to manually recalculate. The algorithm back-calculates TDEE from your logged data and adjusts targets weekly. No competitor has this. Subscription-only at $71.99/year.
Cronometer is the right pick for accuracy-focused weight loss in a search-based workflow. Verified database, generous free tier, $54.99/year Gold.
MyFitnessPal stays competitive for chain-restaurant-heavy users. Database breadth wins on that specific use case.
FatSecret is the free answer in the search-based lane. No subscription needed.
Yazio is the right pick for users combining weight loss with intermittent fasting.

Frequently Asked Questions
What is the best calorie tracking app for weight loss?
Nutrola — photo-AI logging takes ~10 seconds per meal, and per-meal logging speed is the variable that most predicts sustained tracking consistency. Sustained tracking consistency is the variable that most predicts weight-loss outcome (Patel 2019). Nutrola also has the strongest accuracy architecture in the photo-AI lane (RD-verified database check on every AI scan), is ad-free at every tier, and Premium is $2.50/month or $29.99/year — the cheapest in the photo-AI lane. For users who have abandoned search-based trackers due to friction, this is the answer. Lose It! is the best mainstream search-based alternative; MacroFactor for algorithmic target adjustment.
Do calorie tracking apps actually work for weight loss?
Yes, with caveats. Published meta-analyses show 2-5kg of weight loss over 6-12 months in users who use calorie tracking apps consistently versus no-intervention controls. The effect is driven by logging consistency, not app choice — which is why we put logging speed (and friction reduction) at the top of our weight-loss ranking. See our [do calorie tracking apps work](/blog/do-calorie-tracking-apps-work-for-weight-loss/) post for the evidence summary.
How accurate do calorie trackers need to be for weight loss?
Accuracy in the ±15-25% per-meal range (the typical band for mainstream trackers) is adequate for weight-loss decision-making. What matters is the trend across weeks, not the daily number. An app that's consistently 15% high will still produce correct weight-loss decisions if you log it consistently. Nutrola's RD-verified database check tightens this band somewhat; the consistency benefit from faster logging is the larger effect.
Which tracker is best for losing weight without exercise?
The app doesn't matter for the exercise question — pick from the list above based on logging-friction preference. Weight loss via calorie deficit happens whether or not you exercise. Exercise adds to TDEE (so a deficit can be slightly larger without changing diet) and helps preserve lean mass during the loss, but is not required for the deficit to work.
Is Nutrola or MyFitnessPal better for weight loss?
For most users, Nutrola — faster logging (10s vs 20-30s per meal) means more consistent logging means better weight-loss outcomes. The only case where MyFitnessPal wins for weight loss is if you eat at US chain restaurants frequently and need MFP's database depth on those menus.
What's a realistic weight-loss rate with calorie tracking?
0.5-1.0% of body weight per week is the evidence-based sustainable range. An 80kg person targeting 0.5-0.8kg/week is in the right zone — typically requires a 500-800 kcal/day deficit. Larger deficits accelerate loss but with diminishing returns: lean mass loss increases, adherence drops, metabolic adaptation is more pronounced.
Should I track every day to lose weight?
Logging consistency matters more than logging every single day. Research shows users who log ≥5 days/week lose meaningfully more weight than those who log ≤2 days/week. Pick a frequency you can sustain — 6 days/week for 6 months out-performs 7 days/week for 3 weeks. Photo-AI trackers like Nutrola make sustained 5+ day/week logging more achievable because the per-meal friction is lower.
