Written by Flo, founder of Carbsnap. Yes, I make one of the apps in this comparison — so I'll be specific about where MyFitnessPal is better, and you can judge the rest.
MyFitnessPal is the app most people try first. It has the largest food database in the world, a decade-plus head start, and name recognition everywhere. Carbsnap is a much smaller app built for one job: telling you the carbs in the food in front of you, from a photo, in seconds.
Which one you should use depends almost entirely on why you're counting carbs. Here's the honest breakdown.
The core difference: typing vs. snapping
MyFitnessPal is built around search-and-select logging. You type a food, pick the right match from the database, set the portion, and repeat for every item on your plate. Its Meal Scan feature adds photo recognition, but the workflow still centers on the database.
Carbsnap is built around photo-first estimation. You take one photo of your plate, and the AI estimates carbs, protein, fat, and calories for the whole meal — mixed dishes, home cooking, restaurant plates. A typical lookup takes about three seconds.
For a mixed home-cooked plate — say, chicken thighs, rice, and roasted vegetables — MyFitnessPal means finding three or four database entries and estimating each portion. Carbsnap means one photo.
Where MyFitnessPal is genuinely better
Being honest about the competition:
- Barcode scanning and packaged foods. MFP's barcode scanner against its enormous database is excellent. If most of your food comes with a barcode, MFP is hard to beat.
- Recipe importing. Paste a recipe URL and MFP computes per-serving nutrition. Carbsnap doesn't do this today.
- Ecosystem and integrations. MFP connects to more fitness trackers, scales, and apps than almost anything else.
- Community features. Forums, friends, streaks with social accountability — if that motivates you, MFP has it.
Where Carbsnap is better
- Speed on real plates. Three seconds versus several minutes for mixed meals. This matters most when you're estimating carbs many times a day — which is exactly what insulin users do.
- Built for diabetes carb counting. Carbsnap was created with registered dietitians who rated thousands of meal photos during development, and our accuracy methodology was presented at the 2025 American Diabetes Association Scientific Sessions. Carb counting isn't a side feature — it's the reason the app exists.
- Free where it matters. Carbsnap's carb-counting feature is free forever — no subscription, no signup, no payment method. MyFitnessPal has moved more features (including barcode scanning) behind its Premium paywall over the years.
- No surprise charges. Carbsnap has no App Store free trial that converts to a charge you forgot about. You can try full meal logging free for 7 days in the app — no payment method needed to start — and subscribe only if you choose to.

Who should pick which
Pick MyFitnessPal if: you mostly eat packaged/barcoded foods, you want recipe importing and deep integrations, or you're already invested in its ecosystem and it's working for you.
Pick Carbsnap if: you're counting carbs for diabetes or insulin dosing, you eat a lot of home-cooked or restaurant meals, you've tried manual logging before and quit because it felt like a chore, or you want the core feature free rather than metered.
Honestly? Some people use both — MFP for packaged foods, Carbsnap for everything on a plate.
Bottom line
MyFitnessPal is a general-purpose food diary with a photo feature. Carbsnap is a carb counter that happens to log. If carb counting is the job — especially for diabetes — the tool built for the job is usually the better fit.
Carbsnap is free to try on the App Store and Google Play. Snap one meal and see for yourself — no signup required.
