The 30-second verdict
Ember is a better fit if you want to log meals with a photo or a sentence without paying, and track intermittent fasting in a simple interface. Lifesum is better suited if you want to follow a specific diet (keto, Mediterranean, high-protein) with meal plans and recipes, and are happy to upgrade to Premium.
With Lifesum, photo, voice and text logging (“AI Tracking”) is a Premium feature. With Ember, AI analysis is included in the free plan, up to two analyses per day.

Two approaches to food tracking

- Photograph
- Ember estimates calories and macros from a photo on its free plan. With Lifesum, photo logging is part of AI Tracking, reserved for Premium.

- Ember accepts a free-form description such as “chicken wrap, fries, garlic sauce”. Lifesum also supports text and voice logging with Premium.
- Scan
- Ember and Lifesum both read barcodes on packaged products.
- Follow a diet
- Lifesum offers guided diets and meal plans with Premium. Ember keeps your calorie and macro goals at the center, with no set diet.
Strengths and limitations of each app
Ember
Ember focuses on meal logging. A photo or description generates an estimate of calories, protein, carbs and fat. You can correct foods, portions or preparation, then follow your day with water, steps, weight and fasting.
- Strength
- AI analysis you can use for free every day, in an interface focused on the essentials.
- Good to know
- Ember does not offer guided diets, meal plans or a recipe catalog like Lifesum.
Lifesum
Lifesum combines a food diary, guided diets, recipes and a weekly Life Score based on your habits. The free plan includes food search and barcode scanning. Premium adds AI Tracking (photo, voice, text), diets and programs, all recipes and custom macro goals.
- Strength
- Structured guidance for people who want to follow a specific diet.
- Good to know
- Photo logging and most programs require Premium, whose price varies with the offer shown.
Free plan
Ember includes up to two AI analyses per day on its free plan. Lifesum’s free plan includes food search, barcode scanning and basic tracking. AI Tracking, diets, the full recipe catalog and custom macro goals require Premium: on the US App Store, expect from $29.99 per quarter or $99.99 per year depending on the offer shown. Prices and offers may change.
Accuracy
A photo does not always reveal weight, cooking fat, sauces or every ingredient. Results from both apps should be treated as estimates and corrected when you know the portions. Seek advice from a healthcare professional for medical needs.
