MyFitnessPal is a full nutrition app: calories, macros, micronutrients, barcode scanning, and one of the largest food databases available. GramsIn tracks exactly one metric — protein — by text message, with no app to open. If you want to track everything you eat, use MyFitnessPal. If protein is the only number you care about and app-based logging has never stuck for you, GramsIn is faster: most users log a meal in under 10 seconds by replying to a text.

Only if protein is what you track. GramsIn deliberately does not track calories, carbs, fat, or micronutrients. Many users switch from MyFitnessPal because they were only using it for protein anyway; if you use the rest, keep MyFitnessPal.
They are comparable on annual plans (around $80/year), and MyFitnessPal Premium is roughly twice the price month-to-month. MyFitnessPal also has a free ad-supported tier, which GramsIn does not — GramsIn offers a 14-day free trial instead.
There is nothing to open, search, or scan. You reply to a text like "grilled chicken and rice" and GramsIn’s AI estimates the protein and updates your daily total. Logging happens in the messaging app you already use all day.
