Quick verdict
Pick MyFitnessPal if you want the biggest food database and full manual control. Pick Lifesum if you want structured diet plans like Keto or Paleo wrapped in the best-looking interface. But for most people Calally is the better choice: it adds a 24/7 AI coach with full access to your data, plus voice logging. Those two things fix the exact reasons people quit tracking.
MyFitnessPal and Lifesum solve the same problem in opposite ways. MyFitnessPal bets on scale: a massive food database built over more than a decade, with manual logging and total control. Lifesum bets on guidance and polish: structured diet plans and a beautifully designed app that walks you through your day. Both are solid. Both are also manual, and both leave you alone with the data.
That's the gap worth naming. Tracking fails for two reasons, logging is tedious and nobody tells you what your numbers mean. Calally was built to fix both. It's a calorie tracker built around a personal AI coach, with voice logging as the enabler. You describe a meal, the AI estimates the macros, you tap once. Then the coach, which sees all your data, actually helps. Here's how the three compare.

Does either app coach you?
No. Neither MyFitnessPal nor Lifesum coaches you. Both record what you eat and show you charts, but the analysis is your job. You see the numbers and have to decide what they mean and what to change. That's fine if you're experienced. For most people, it's the moment motivation runs out.
Calally takes the opposite approach. Its AI nutrition coach has full, ongoing access to your eating history. Ask why you stalled, what to eat before a workout, or how to hit your protein, and you get a real answer grounded in your own data. Neither competitor offers anything close to this. It's the single biggest reason Calally is our top pick.
MyFitnessPal vs Lifesum: database or diet plans?
This is the real fork between the two. MyFitnessPal's strength is its food database: over 10 years of entries means almost any food, brand, or restaurant item is already there. You get manual control and unmatched coverage, though the free tier now carries ads and pushes barcode, voice, and meal-scan into Premium.
Lifesum trades catalog size for structure and design. Its diet plans (Keto, Paleo, High-Protein, Vegan) give you a guided framework instead of a blank slate, and the interface is genuinely the nicest of the two. The catch is the free tier, which works more like a demo than a usable tool. Both apps still rely on manual logging.
How does logging compare?
Both MyFitnessPal and Lifesum are manual. You search, scan a barcode, or tap through menus for every item, every meal, every day. It's accurate, but it's friction, and friction is why most people quit calorie tracking within weeks. The act of logging becomes the chore that ends the habit.
Calally removes that friction. You describe the meal out loud, "two eggs, toast, and a coffee with oat milk," and the AI estimates the macros and logs it in seconds. No catalog hunting, no barcode. It's less precise than a database lookup for packaged foods, but for everyday eating it's far faster, which is what keeps people tracking long enough to see results.
Which should you choose?
Be honest with yourself about what you need. Choose MyFitnessPal if database coverage and full manual control matter most, especially for packaged and restaurant foods. Choose Lifesum if you want a structured diet plan and the most polished interface to follow it in.
For most people, though, Calally is the better choice. The coach and voice logging fix the two reasons tracking usually fails: it's tedious, and no one tells you what to do with the numbers. The free trial includes everything, so you can test the difference yourself.
