Weight-loss apps are a category that has changed dramatically in the last five years — partly because of better food databases and barcode scanning, partly because of the rise of GLP-1 medications that have shifted what "weight loss support" means, and partly because the apps that survived the pandemic-era boom are now meaningfully more polished than the ones that didn't. The seven below are the most useful Android-side options as of mid-2026, picked for actual day-to-day usefulness rather than marketing reach.
One thing worth establishing up front. No app loses weight for you. The mechanism by which apps help is structural: they make tracking easier, they surface patterns you wouldn't otherwise see, and they impose enough accountability that the eating-and-movement pattern actually changes. The best app for you is the one you'll actually open most days for several months. A clever feature set on an app you abandon in three weeks isn't worth a simpler app you stick with.
The list covers different jobs: full-featured calorie tracking, photo-based food logging, fasting timers, behaviour-change coaching, fitness-integrated tracking, and the lighter-touch habit-formation apps. Some adults will use one; some will combine a tracker with a fasting timer or a workout app. The right combination depends on what's been failing — if you've been tracking diligently and not losing, an accountability or coaching layer matters more; if you've never tracked, start with one full-featured tracker before adding anything else.
1. MyFitnessPal
MyFitnessPal remains the most-used calorie tracker on Android, and the food database — built over 15+ years of user contributions — is still the most comprehensive available, including a reasonable selection of Indian, Chinese, Mexican, and other non-Western foods that competing apps thin out on. Barcode scanning is fast and reliable. Restaurant chain menus are usually accurate. Macro tracking, recipe building, and meal-template saving are all in the free tier.
The downside: aggressive premium upsells over the past few years, and an ad-heavy free experience. The premium tier is now genuinely useful (deeper macro analysis, custom goals, no ads) but the price has crept up. For most users, the free tier handles the actual job — daily calorie logging — adequately. The 2024 ownership change to Francisco Partners has slowed the pace of feature changes, which is fine if you liked it as it was.
Best for: serious calorie tracking, large food database needs, anyone who has tried other apps and bounced because the database was incomplete.
2. Cronometer
Cronometer is the calorie tracker for people who care about micronutrient detail beyond just macros. Where MyFitnessPal tracks calories, protein, carbs and fat by default, Cronometer tracks 80+ nutrients including specific amino acids, vitamins, minerals, and key trace nutrients. The food database is smaller than MFP's but the entries are vetted to a higher standard (each food is sourced from a reference database, not crowdsourced).
The interface is denser and less designed-for-beginners than MFP's, which is the trade-off: more accurate, more detail, slightly higher learning curve. Particularly useful for adults with specific medical or nutritional concerns (anaemia, vitamin D deficiency, kidney conditions where potassium tracking matters, ketogenic dieting where exact macro percentages affect outcomes).
Best for: micronutrient-focused tracking, plant-based eaters wanting to verify B12 and iron, anyone whose tracking needs are more clinical than casual.
3. Lose It!
Lose It! is the cleaner-design alternative to MyFitnessPal. The interface is faster to navigate, the goal-setting flow is friendlier for beginners, and the photo-based food logging (Snap It feature) has improved meaningfully in the last two years — you can now photograph many common meals and get a reasonable estimate without manual logging. The food database is large enough to handle most common foods, though it thins out on regional and ethnic cuisines compared to MFP.
Premium adds meal planning, more detailed macro analysis, and challenge programmes that some users find genuinely useful for accountability. The free tier is reasonable for basic tracking.
Best for: beginners to tracking who find MyFitnessPal cluttered, users who prefer a calmer interface, and anyone interested in photo-based food logging.
4. Noom
Noom is a behaviour-change app dressed up as a weight-loss tracker. The actual calorie tracking is functional but not best-in-class; what Noom does differently is daily lessons, psychology-focused content, and the colour-coded food categorisation (green / yellow / red foods by calorie density) that quietly trains better intuition without strict counting. The coaching layer — human coaches in earlier versions, increasingly AI in 2026 — is the differentiator.
The product has had a turbulent few years on pricing and user reviews; the actual programme has solid behaviour-change research behind it but is meaningfully more expensive than MFP or Lose It! Premium. Worth trying the free trial if you've been tracking calories diligently for months without behaviour change sticking — that's the specific failure mode Noom addresses well.
Best for: adults whose tracking knowledge isn't the issue but whose habits haven't shifted, people who respond well to daily psychology content, and users who want more structure than a pure tracker provides.
5. Zero (intermittent fasting tracker)
If your eating pattern is built around intermittent fasting — 16:8, OMAD, or longer fasting protocols — Zero is the most established and best-designed fasting tracker on Android. The interface is simple: set your fasting window, the timer tracks it, and the app surfaces sleep, mood, and weight data alongside fasting history. Recent versions integrate with Apple Health and Google Fit reasonably well.
The premium tier adds content, longer-fast guidance, and biomarker tracking. For most users the free tier is enough — the core job (an honest fasting timer with progress tracking) is well-handled at the no-cost level. Pair with one of the calorie trackers above if you need both food logging and fasting structure.
Best for: committed intermittent fasters, anyone using a time-restricted eating window who wants visibility into adherence, and users who find calorie tracking exhausting and want a structural alternative.
6. Google Fit (plus a smartwatch)
Google Fit isn't a weight-loss app per se, but as the activity-tracking backbone — particularly when paired with a Wear OS watch or any compatible fitness band — it's the most reliable Android-native way to track steps, heart rate, sleep, and overall movement. Most other apps on this list integrate with Google Fit, so it acts as the data layer that powers tracking elsewhere.
The 2024-2026 redesign meaningfully improved the heart-rate-zone insights and the sleep summary. For weight loss specifically, the most useful Fit metric is daily step count and active minutes — both of which are strong proxies for the non-exercise activity (NEAT) that drives a significant fraction of fat loss.
Best for: activity tracking as part of a broader weight-loss approach, Android users with a Wear OS or compatible fitness band, anyone wanting their step and movement data to feed into other apps.
7. Yazio
Yazio is the European-focused alternative to MyFitnessPal — better food database for European packaged foods, cleaner interface than MFP, and a meal-plan layer that's stronger than most competitors. Particularly useful for users in the UK and EU whose local food brands are missing or wrongly categorised in the American-leaning databases of MFP and Lose It!.
The premium tier adds meal plans, recipes, and detailed nutrition tracking; the free tier handles basic calorie and macro logging. Worth a trial if you've struggled with database accuracy on MFP for UK or European supermarket products.
Best for: UK and European users, anyone whose previous tracking attempts failed because the food database was American-centric, and users who want meal plans alongside tracking.
Where this leaves you
The single most important framing: pick one and use it for at least 8 weeks before judging it. The "best app" question is much less interesting than the "what gets you to log every day" question, and that depends on your specific friction points — interface preference, food database needs, whether you want behaviour-change content alongside tracking, and whether your eating pattern is calorie-based or structural (fasting, time-restricted eating).
For most people starting from zero, MyFitnessPal or Lose It! handle 80% of the job at no cost. If you find yourself wanting more depth, Cronometer is the upgrade. If you find yourself tracking diligently but not changing behaviour, Noom is the targeted intervention. If your approach is structural rather than counting-based, Zero plus Google Fit covers the relevant data without forcing you to log every meal. Stack apps thoughtfully — one tracker, one structural tool, one activity layer — and the combined picture is usually enough.
One final note worth registering: the new pharmacological landscape (GLP-1 agonists) has changed what apps are useful for. Adults on semaglutide or tirzepatide often find appetite is no longer the primary issue — but logging still matters for adequacy of protein and micronutrients, particularly because reduced intake can underdeliver on both. Cronometer is particularly useful in that context; ask your doctor or dietitian what tracking would help.
