This comparison comes from the Joules team, so read it knowing who wrote it. Here is the honest split. MyFitnessPal is the incumbent with the largest food database in the category, more than 20 million claimed entries, plus years of integrations; if database depth is your priority, it wins and this page will not pretend otherwise. Its weak points are price and friction: Premium costs $19.99 a month or $79.99 a year as of mid-2026, the free tier carries ads, and barcode scanning left the free plan in October 2022. Joules is the challenger, and it is built for one thing, logging speed. Photograph the plate, confirm the AI's read in a tap, and the log is done in about a second, with a daily health score, macro rings, an intermittent fasting timer, habit streaks, and Apple Health and Google Fit sync, no ads. The table below puts the differences side by side.
Side by side
| Feature | MyFitnessPal | Joules |
|---|---|---|
| Photo logging | Meal scan, in Premium | Core feature, with a confirm step |
| Food database | 20M+ claimed entries — the leader | Smaller; MyFitnessPal wins here |
| Daily health score | No single daily score | Yes, one number with reasons |
| Macros | Custom targets in Premium | Macro rings in the daily view |
| Habits and fasting | Fasting tracking in Premium | Habit streaks and a fasting timer built in |
| Health sync | Apple Health, Google Fit, wearables | Apple Health and Google Fit |
| Ads | Yes on the free tier | None |
| Best known for | A decade-plus of data and integrations | Fast logging and one clear daily picture |
Where MyFitnessPal is better
The database, first and clearly. More than 20 million claimed entries means restaurant meals, regional brands, and obscure packaged foods usually already exist, and no rival, Joules included, matches that today. MyFitnessPal has also run since 2005: the integrations with fitness devices are broad, the recipe and community content is deep, and the product has been stress-tested by an enormous user base. If you eat out constantly, scan a lot of unusual products, or want the app with the longest paper trail, MyFitnessPal is the safer pick, and Premium at $79.99 a year is the version actually worth having.
Where Joules is different
Joules starts from the observation that most tracking failures are logging failures. Each meal costs 30 to 60 seconds of searching and portion-guessing in a traditional tracker, and that tax is why streaks die in week three. In Joules you photograph the plate, the AI drafts the entry, and you confirm or correct it in a tap. That confirm step is deliberate: photo AI is an estimator, not a scale, and pretending otherwise produces bad data. Around the log, Joules keeps the whole picture in one place, a daily health score with reasons, macro rings, habit streaks, an intermittent fasting timer, and Apple Health and Google Fit sync, with no ads at any tier. The free calculators on this site are the part you can use without the app at all.
Which one should you pick?
MyFitnessPal is better if…
- Database coverage decides it for you: restaurants, brands, international foods.
- You already pay for Premium and the streak is working. Do not break momentum.
- You want years of reviews and device integrations before trusting an app.
Joules is better if…
- Logging time is why every previous tracker failed you.
- You want habits, fasting, weight, and food in one view instead of four apps.
- Ads in a health app bother you.
- You would rather judge an app on how it feels day to day than on how long it has been around.
The honest bottom line
MyFitnessPal earned its position, and for database-first users it is still the right answer. Joules is not trying to out-database a 20-year incumbent. It is trying to make the daily log cost a second instead of a minute, and to show one score instead of ten charts. If that is the problem you have, the download page has the details, and you can run it next to your current tracker for a couple of weeks. Before either app, set your target: the free TDEE calculator and macro calculator give both apps the same starting numbers. For the wider field, see the best calorie tracking apps roundup.
