App Comparison

Lifesum vs MyFitnessPal

Fuel Nutrition Team • March 16, 2026

Lifesum and MyFitnessPal take different approaches to the same market. MyFitnessPal is the incumbent — the largest food database in nutrition tracking, the app everyone's heard of. Lifesum is the challenger — pivoting to AI-powered logging to leapfrog database dependency. Both have trade-offs that affect daily use.

Food Logging

MyFitnessPal's 14-million-entry database is unmatched in coverage. Whatever you eat, you'll probably find it. The catch: barcode scanning — the most practical way to use that database — is locked behind a $19.99/month Premium subscription. And the data is crowd-sourced, so accuracy varies entry to entry.

Lifesum's AI text logging skips the database entirely — describe your food and get estimates. It's faster when it works, but accuracy is questioned, corrections were removed in the AI update, and meal structure was replaced with a flat list that mis-assigns foods.

Monetization

MyFitnessPal's monetization is aggressive: intrusive ads including graphic food imagery in the log feed, and a $19.99/month Premium tier that paywalls barcode scanning. The free tier feels designed to annoy you into upgrading.

Lifesum's monetization is lighter. Ads are minimal, and Premium at $9.99/month — half MFP's price — unlocks diet plans, recipes, and full features without the same upsell intensity.

Beyond Tracking

Lifesum offers diet plans, recipes, and a Life Score system behind its subscription — lifestyle features MyFitnessPal doesn't match. MyFitnessPal has community features and a larger ecosystem of integrations, but no structured diet plans or lifestyle scoring.

Stability

MyFitnessPal is the more stable daily tool. Despite its monetization issues, core tracking works consistently.

Lifesum's AI pivot introduced instability: the tracker breaks after updates, behavior reverts without explanation, and paid users report being unable to add foods.

Verdict

If you need the largest food database and don't mind aggressive monetization, MyFitnessPal's coverage is unmatched. If you want AI-powered logging with diet plans at a lower price and can tolerate the instability, Lifesum offers a more forward-looking (if less reliable) approach. Neither offers coaching or adaptive goals.
