The weight loss app market has a subscription problem. Most popular apps offer a free tier that's so limited it's barely functional, then charge $15–25 per month for the features you actually need.
These are the weight loss apps that are genuinely free — no subscription required to access core functionality — ranked by how useful they actually are.
What "Genuinely Free" Means
For this list, we tested whether each app's free tier includes:
- ✅ Calorie tracking
- ✅ Macro tracking (protein, carbs, fat)
- ✅ Food database or barcode scanning
- ✅ Progress tracking
- ✅ Useful without paying anything
If the core functionality is locked behind a subscription, it didn't make the list.
1. NutriBalance — Best Genuinely Free Weight Loss App (Android)
Price: Free (optional premium) Platform: Android
NutriBalance gives you the full calorie and macro tracking experience for free, with no features crippled by a paywall. Everything the app is built around — calorie counting, macro tracking, barcode scanner, AI food scanner, streak system, daily missions, leagues, friends leaderboard, and the Android widget — is available without paying anything.
Free forever features:
- Calorie counter and food diary
- Macro tracking (protein, carbs, fat, fibre)
- Barcode scanner for packaged food
- AI food label scanner
- Custom calorie and macro goals
- Daily streak system
- Daily missions with chest rewards
- ~40 achievements
- Weekly league system
- Friends leaderboard
- Android home screen widget
- Water intake tracker
- Weight tracker with progress charts
- AI nutrition coach
- Available in 6 languages
Why it works for weight loss specifically: The streak and mission system solves the #1 problem with weight loss apps — people quit them within two weeks. By gamifying the logging habit, NutriBalance keeps you tracking for months instead of days. And consistent tracking is the most evidence-backed predictor of weight loss success.
Weight tracker: Log your weight daily and view your trend over time in the built-in progress charts. NutriBalance shows your 7-day rolling average alongside daily weights, which is the most accurate way to track fat loss progress through normal weight fluctuations.
2. FatSecret — Best Free Minimalist Option
Price: Free (completely) Platform: Android, iOS, Web
FatSecret is genuinely free with no paywalled core features. Calorie tracking, macro display, food diary, barcode scanner, and a basic community are all free. The interface is dated and there's no gamification, but for users who just want the basics without complexity, it works.
What's free: Everything. FatSecret's revenue model is based on ads and a premium tier that adds recipe suggestions — not behind a hard feature paywall.
Downside: No gamification means no motivation mechanics. The app is a tool, not an experience — you'll need internal motivation to keep logging.
3. Samsung Health — Free for Samsung Users
Price: Free (pre-installed) Platform: Android (Samsung devices)
Samsung Health is pre-installed on Samsung phones and includes calorie tracking, step counting, sleep tracking, and basic food logging. The food database is smaller than dedicated trackers and the interface is less streamlined — but it's zero-friction if you have a Samsung phone.
Best for: Samsung phone owners who want basic tracking integrated with their existing health data.
Apps That Claim to Be Free But Aren't
MyFitnessPal Free: Calorie tracking is free, but the barcode scanner on Android now requires premium ($19.99/month). The ad load is heavy. Increasingly restrictive.
Lose It! Free: The free tier is extremely limited — macro tracking and barcode scanning require premium ($39.99/year). Essentially unusable as a free tracker.
Noom: Marketed as a behavioural weight loss app. There is no meaningful free tier — the program costs $70/month.
WW (Weight Watchers): Point-based system. No free tier. ~$25/month.
Why Most Weight Loss Apps Cost Money Now
The app market shifted significantly from 2020 onwards. Apps that launched with generous free tiers discovered that free users don't convert to paying customers at sufficient rates — so they've progressively restricted free functionality to force upgrades.
The exceptions are apps that monetise differently:
- Ad-supported models (FatSecret)
- Freemium with genuinely useful free tiers (NutriBalance — revenue from optional premium and ads that don't impede core use)
- Pre-installed manufacturer apps (Samsung Health)
What to Look for in a Free Weight Loss App
Core functionality must be free: If calorie tracking, macro display, or food scanning require payment, the app isn't worth your time — better free alternatives exist.
Sustainability tools: Does the app help you stay consistent? Gamification (streaks, missions, leaderboards) dramatically improves long-term adherence compared to apps that are just logging tools.
Progress tracking: A weight tracker with trend visualisation is essential for tracking fat loss through daily fluctuations.
Food database quality: Can you find the foods you actually eat? A large, accurate database reduces friction.
No functional ads: Ads are acceptable if they don't interrupt core functionality. Ads that block the diary or require dismissal before logging are a dealbreaker.

Frequently Asked Questions
Is there a truly free calorie tracking app? Yes. NutriBalance (Android) and FatSecret (Android/iOS) are genuinely free with no core features behind a paywall.
What happened to the free version of MyFitnessPal? MyFitnessPal has progressively moved features behind its premium subscription. The barcode scanner on Android now requires premium. The free tier is significantly less useful than it was before 2022.
Can I lose weight with a free app? Absolutely. Weight loss depends on calorie tracking accuracy and consistency — not on which tier of app you're using. A free app used consistently every day produces better results than a premium app used sporadically.
What is the best free weight loss app for Android in 2026? NutriBalance is the best free weight loss app for Android in 2026. It combines complete calorie and macro tracking with a gamification system (streaks, missions, leagues) that significantly improves long-term tracking consistency.
