The free all-in-one alternative to MyFitnessPal, Cal AI & SNAQ.
Every major calorie counter charges $30–$80/year — and none of them include workouts. Carb Lens combines AI photo meal scanning, macro tracking, guided workouts and a daily health score in one app. Free forever.

One app for both sides of your health
Calorie trackers are nutrition-only. Workout apps are exercise-only. Carb Lens is the rare app that does both — so your daily score reflects what you ate AND what you moved.
AI meal scanner
Snap a plate — calories, carbs, sugar, protein in 1 second.
Guided workouts
5–15 min routines for fat burn, muscle, cardio, abs & full body.
Daily health score
One number that combines nutrition, movement and streaks.
Glycemic impact
Green / amber / red — at-a-glance blood-sugar safety.
Frequently asked
Is Carb Lens really a free alternative to MyFitnessPal?+
Yes. Carb Lens is 100% free for unlimited meal logging, workouts, dashboard, streaks and your daily health score. MyFitnessPal locks barcode scanning, meal scan, custom goals and macro breakdowns behind their Premium plan (around $19.99/month or $79.99/year). Every one of those features is free in Carb Lens.
How does Carb Lens compare to Cal AI?+
Cal AI is an AI photo calorie scanner that charges roughly $9.99/week or $29.99/month after a short trial. Carb Lens does the same one-tap photo scan — calories, carbs, sugar, protein and fat — for free, and also includes guided workouts, a glycemic-impact score and a full daily dashboard that Cal AI doesn't have.
What about SNAQ, Lose It, Noom and MyNetDiary?+
SNAQ Pro is ~$59.99/year, Lose It Premium ~$39.99/year, Noom ~$70/month, and MyNetDiary Premium ~$59.99/year. They all paywall their best features (AI scanning, custom macros, coaching, ad removal). Carb Lens gives you AI meal scanning, custom macro goals, workouts and an ad-light free tier with no subscription required.
Is Carb Lens really all-in-one (nutrition AND workouts)?+
Yes — that's the main difference. Most calorie trackers (MyFitnessPal, Cal AI, SNAQ, Lose It) are nutrition-only and want you to bring a separate workout app. Carb Lens includes a full library of guided 5–15 minute workouts (fat burn, muscle, cardio, abs, full body) plus manual workout logging — so one app covers both sides of your daily health score.
What's the catch with the free tier?+
There isn't one in the traditional sense. The free tier includes 2 AI photo scans per day (you can earn more by watching short rewarded ads or by hitting a 7-day streak), unlimited manual food logging, unlimited workouts, the dashboard, weekly trends and the health score. Pro ($ optional) unlocks unlimited AI scans, glucose-response forecasts, smart swaps, PDF reports and removes ads.
Does Carb Lens work on iPhone, Android and the web?+
Yes. Carb Lens runs in any browser at carblens.org and is available as a native iOS app. Your account, scans, streak, workouts and subscription sync across every device using the same email.
