The classic calorie app asks you to search a database, pick one of twenty entries for "chicken curry", then guess the grams. AI trackers flip that around: you photograph, say or type the meal and the app estimates it. That's a big deal for consistency, because the best tracker is the one you'll still be using in a month.

Prices below are approximate list prices at the time of writing (November 2026). Apps change prices often and vary by country, so check the app before you subscribe.

What to look for

  • How you log. Photo, voice, typed text or barcode. Photos are quick for a single plate; text and voice handle mixed meals, home cooking and "half of what my friend ordered" better.
  • Your food. Does it understand what you actually eat, in the portions you actually eat it? Coverage of non-US cuisines varies a lot.
  • Editing. AI estimates are a starting point. You should be able to fix a portion or an ingredient in a tap.
  • Price and free tier. Some apps have generous free plans; others are subscription-only after a trial.

The main options

MyFitnessPal

The biggest food database and the longest track record, with barcode scanning and a large community. AI meal scanning and other conveniences sit behind Premium, which lists at about $19.99/month or $79.99/year in the US. Database entries are user-submitted, so quality is mixed, especially for home-cooked and regional dishes.

Cal AI

A photo-first app: point your camera at your plate and it estimates the meal. Very quick for single, recognisable dishes. Reported pricing is around $29.99-39.99/year, with monthly plans higher. Photos struggle with things a camera can't see, like oil, butter, or what's inside a wrap.

Lose It!

A long-running tracker with a friendly design, barcode scanning and photo logging. Premium is reported at roughly $40-80/year depending on offers. Good for people who like a structured daily budget and streaks.

MacroFactor

Built around an adaptive algorithm that adjusts your targets from your real weight trend, popular with people serious about macros. Around $71.99/year with a free trial and no permanent free tier.

Cronometer

Best in class for micronutrients (vitamins and minerals) with carefully curated data. Gold is reported at roughly $50-60/year. More detail than most people need, but excellent if you want it.

DietTracker

Built around describing your meal in plain language, by voice or text, in your own words: "two slices of pepperoni pizza and a Coke", "full English with an extra sausage", or "do roti aur dal". It estimates calories and macros for the portion you describe, understands food from many kitchens (it was built first for Indian food, which most apps handle badly), and asks a follow-up when a portion is unclear. Photo and barcode logging are part of Pro. Logging by voice and text is free, and Pro is $4.99/month or $29.99/year (₹99/month or ₹799/year in India), with a 30-day free trial.

Which one should you pick?

  • You eat lots of packaged food: a big barcode database (MyFitnessPal, Lose It!) helps.
  • You mostly eat simple, single plates: photo-first apps are fast.
  • You care about vitamins and minerals: Cronometer.
  • You want adaptive macro coaching: MacroFactor.
  • You cook at home, eat mixed or regional dishes, or just hate searching databases: describing the meal is quicker and usually more accurate than a photo, because you can mention the oil, the portion and what's inside.

Whatever you choose, accuracy comes from logging every day, roughly right, rather than perfectly on good days only. If you're working out a target first, read how many calories you should eat to lose weight, or try DietTracker free.
