Choose Lose It! if you want a long-running tracker with GLP-1 medication support, apps for Android, iPad and Apple Watch, or a one-time lifetime purchase. Choose Calorix if you’re on iPhone and want a free barcode scanner and free daily AI scans, each ingredient of a photo estimate listed with its grams and a confidence badge, the app in more languages, and Toasty, a living pet who eats, drinks and celebrates with you as you log.
We make Calorix, so we’re not neutral. That’s why every claim about Lose It! on this page comes from a public source (its App Store listing, its own website, its help center or press coverage) and was checked on October 11, 2026. Prices are US App Store prices; they vary by country and can change, including through A/B tests.
Logging and AI
Lose It! sums up its logging as “Say It. Snap It. Scan It.” on its website. Its App Store listing names photo meal logging, AI voice logging (for example, saying “I had 2 eggs, toast with butter and jam”) and the barcode scanner as Premium features, backed by a food database the listing puts at more than 56 million items and recipes. The website adds that the scanner can create new foods by auto-filling them from a nutrition label.
Calorix starts from the camera. You photograph a meal and get a review card that lists each ingredient with its portion, grams, calories and a confidence badge. You can also scan a barcode or a nutrition label, describe a meal by text or voice, or use food search, recents, favorites, custom foods, the recipe builder and quick-add calories. Here’s how the Calorix scanner works.
Editing and accuracy
Lose It! was one of the four apps in a preliminary NIH study presented at NUTRITION 2026. Researchers ran photos of 102 weighed meals through the apps, and all four underestimated calories by about 250 to 345 kcal per meal on average, roughly a third, and fat by about 30 g (EurekAlert, Healio). The release noted that Lose It! and MyFitnessPal estimated higher-calorie meals more accurately than lower-calorie ones, and one of the researchers, Aaron Hengist, advised checking portions rather than taking photo results at face value. Calorix was not part of the study, and we don’t claim it would do better.
Lose It!’s help center says Snap It lists the detected foods with an estimated serving size, which you can swap for another food or edit before logging (Lose It! help). In Calorix, you edit at the ingredient level: change a portion or the grams, add or remove items, use the portion slider, or tell Fix with AI what to change by text or voice, with each change shown for your approval before it’s applied. You can add a note like “cooked in butter” and re-analyze the meal from the stored photo. There’s more in How accurate are AI calorie apps?
Targets and tracking
Lose It! builds a personalized calorie budget and schedule from your profile, and its listing mentions calorie schedules that let you plan to eat more on weekends. Premium adds advanced tracking of macros, nutrients and health metrics such as blood pressure, glucose, cholesterol, body measurements and sleep, plus intermittent fasting and meal planning. GLP-1 support lets you log your medication and view estimated GLP-1 levels alongside food, weight and activity. Lose It! also tracks water and syncs with Apple Health, Google Fit, Fitbit, Garmin and Withings.
Calorix sets daily targets for calories, protein, carbs, fat, fiber and water using the Mifflin-St Jeor equation, with the pace capped at 1% of body weight per week and calorie floors of 1,200 kcal a day for women and 1,500 for men. It suggests meal ideas that fit your remaining macros, shows a weight trend with a projected goal date and keeps progress photos. Fasting covers 12:12, 14:10, 16:8, 18:6, 20:4, OMAD and custom schedules, with a timer, reminders, a Live Activity and a widget. Apple Health works both ways: Calorix reads steps, workouts and weight, and writes calories, macros, water and body mass. Calorix doesn’t offer GLP-1 dose tracking. See the macro tracker and the fasting tracker.
Motivation: streaks, community and mascot
Lose It! offers logging streaks and celebrations of your milestones, and a community tab where you can add friends and join groups (How Lose It! works).
Calorix uses Toasty, an original ember mascot whose energy grows as you keep up your habits. Toasty never shames a food or comments on your body. Daily and weekly challenges earn coins for Toasty’s outfits, and at launch coins are earned, not sold. Streaks come with earned freezes and a sick-day pass, and neither is ever sold. Smart reminders are capped at two a day.
Platforms and languages
Lose It! has been on the App Store since November 2008. Its listing shows iPhone and iPad (iOS 18 or later), Apple Watch, Mac with Apple silicon and Apple Vision Pro, in 8 languages, and its website links to the Android app on Google Play.
Calorix 2.0 is iPhone-only and runs on iOS 17 or later. There’s no Android, iPad or Mac version, and an Apple Watch app is planned but not available yet. The app comes in 16 languages, including Italian, Dutch, Arabic, Turkish, Vietnamese, Indonesian and Traditional Chinese, none of which appear among the eight languages in the Lose It! listing.
Pricing and trial
Lose It! Basic is free. Its help center lists Premium at $79.99 a year, auto-renewing, and Lifetime as a one-time $299.99 ($229.99 for current Premium members), with no refunds on Lifetime (Lose It! help). New users can try Premium free for 7 days, and Lose It! says prices vary with promotions and “most users will receive discounted offers while using the app”, which fits the lower prices in its US App Store purchases: Premium from $9.99 to $79.99 and Lifetime at $49.99 or $59.99 (checked October 11, 2026). One more detail: new US subscriptions started in the latest app in 2026 are billed by Stripe rather than Apple, so they’re canceled in the app’s account settings and refundable within 5 weeks (Lose It! help).
Calorix is free to download and has a free version: barcode lookups, food search and manual logging with no limit, and 3 AI scans a day. Pro costs $3.99 a week, $9.99 a month or $39.99 a year after a 3-day free trial (US App Store prices on October 9, 2026; they vary by country). You manage or cancel the subscription in Apple’s Settings. Accounts are optional: Sign in with Apple or Google is only for backup and sync, and you can delete your account in the app.
