Best overall: Lose It!

Lose It! is one of the strongest free weight loss apps for people who want fast food logging without a steep learning curve. The free version is easy to use, has a large food database, supports barcode scanning in many regions, and makes daily calorie targets simple to follow.

It made the list because it balances simplicity and usefulness better than many competitors. If your biggest challenge is staying within a calorie budget, Lose It! is a practical first pick.

Best for macro and micronutrient detail: Cronometer

Cronometer stands out if you want more than calories. Its free tier is especially good for people who care about protein, fiber, vitamins, and minerals, not just a total calorie number.

It made the cut because accurate nutrient tracking can help you make better food choices while dieting. It’s a strong option for anyone lifting weights, following a higher-protein plan, or trying to improve diet quality while losing weight.

Best for free workouts: Nike Training Club

Nike Training Club is one of the best free workout apps for fat loss support because it gives you structured training without requiring equipment. You can follow strength, mobility, and conditioning sessions at home or in the gym.

Weight loss usually works better when calorie control is paired with regular activity, and this app makes exercise feel organized instead of random. It’s a smart pick if you want guided workouts rather than just a food tracker.

Best for beginners: MyFitnessPal

MyFitnessPal remains a popular free option for beginners because the app is familiar, the interface is straightforward, and the food database is broad. It’s a good starting point if you want a simple place to log meals and watch patterns over time.

The free version is more limited than it used to be, so it’s not the best choice for power users. But for someone new to tracking, it still earns a place on a best free weight loss apps list because it lowers the friction of getting started.

Tips

• Pick one app for food and one for movement instead of trying to track everything in five places.
• Log meals before you eat when possible; the habit is usually easier than entering everything at night.
• If you lift or do bodyweight training, prioritize protein tracking and progressive workouts over chasing a low calorie number.
• Use weekly trends, not daily scale changes, to judge whether the app is helping.
• If you want better home workouts, Fitnit can help with AI-powered form analysis and automatic rep counting for exercises like push-ups, squats, pull-ups, crunches, and curls.
