Carb Manager app: is it free, what Premium costs and free alternatives

Yes. Carb Manager states that the app is free to install and use, and that unlimited barcode scanning and net carb tracking stay free: you can log food from a database of over a million foods, count calories and macros, and track water, exercise and weight without paying. Premium, marked with a trophy in the app, is where recipes, meal plans, fasting, diabetes tracking, micronutrient goals, reports, voice and photo logging and device syncing sit.

Carb Manager Premium is $8.49 for one month, $16.49 for three months or $39.99 for a year in the US App Store, which matches the monthly, quarterly and yearly options on Carb Manager's site ($3.33 a month when billed yearly). The listing also shows $24.99, $29.99 and $49.99 entries, one of them named Premium Annual Special, without saying when each is offered. US App Store prices on October 30, 2026; they may change.

AppHunt has no promo code for Carb Manager, and its Premium page, help center and App Store listing don't mention promo or coupon codes. The saving Carb Manager does show is for paying longer: its site puts the yearly plan at $3.33 a month, against $5.50 for the quarterly plan and $8.49 for a single month, and the App Store listing carries the cheaper yearly entries mentioned above.

Carb Manager doesn't say. Its Premium page, help center and App Store listing mention no free trial of Premium; what you can try first is the free account, which Carb Manager says is always free to use. If a trial is offered on the purchase screen, cancel at least a day before the billing cycle ends, as Carb Manager's help center advises for any cancellation, and remember that deleting the app doesn't cancel anything.

In the app, go to Settings, then Subscription, tap Manage Subscription and choose the button for the store where you bought it: App Store, Google Play or Web. Do it at least a day before the billing cycle ends; uninstalling the app doesn't cancel. You keep Premium until the paid period ends, and afterwards you keep the logs, foods, recipes and meal plans you created. Apple handles refunds for App Store purchases; for web and Google Play purchases Carb Manager honors requests made within seven days and doesn't prorate.

Carb Manager has 736,421 ratings averaging 4.8 in the US App Store. Among the 250 most recent US reviews, written from January 10 to October 21, 2026, people like the free barcode scanner, the net carb and macro tracking and the help with weight loss, and several say the free version is enough, even if they no longer follow keto. The complaints include recipes and other tools locked behind Premium, bugs and slow loading, trouble cancelling or being charged after cancelling, one reviewer who says old logs became unavailable without Premium and another who says data export is paywalled.

For low-carb tracking, Carb Manager's own free account is hard to beat: it already covers net carbs and barcode scanning, and what it keeps for Premium is the recipes, meal plans and other tools listed above.
