Corpus vs MyFitnessPal
Short answer: MyFitnessPal is a calorie and nutrition tracker with one of the largest food databases around. Corpus is built for people who lift: it logs strength training in detail next to your nutrition, sleep and recovery, tracks nutrients like amino acids and omega-3s, and shows how your eating affects your training. Pick MyFitnessPal for calorie counting; pick Corpus if food is one part of your training.
| Feature | Corpus | MyFitnessPal |
|---|---|---|
| Food and macros | Barcode scanning, macros per meal and per day, supplements, caffeine and water | Very large food database, barcode scanning, meal and macro tracking |
| Micronutrients | 21 minerals and vitamins (each marked measured or estimated), fatty acids down to EPA and DHA, and every essential amino acid | Selected vitamins and minerals alongside calories and macros |
| Protein quality | Leucine per meal and every essential amino acid against a reference pattern, protein scaled to your bodyweight | Protein in grams against your macro goal |
| Energy for training | Energy availability: the energy left for your body after training, with published thresholds | A daily calorie goal, with exercise calories added back |
| Strength training | Sets, reps, weight and RPE, with RIR per set in Advanced mode, machine settings remembered per exercise and multi-pin machines logged pin by pin | Basic: log exercises with sets and reps, without progression tracking |
| Sleep and recovery | Sleep stages, overnight HRV, resting heart rate and a daily readiness score, synced from your wearable or logged by hand | Not the focus of the app |
| Insights | Tests how your own sleep, food and habits relate to your training and recovery, with corrections for multiple comparisons | Nutrition reports and progress towards your calorie and macro goals |
