About KetoLens: Keto Carb Counter
Photograph your meal. KetoLens estimates the net carbs and tells you if it will keep you in ketosis - an AI keto tracker and carb counter built for low-carb eating, not generic dieting. No weighing, no barcode hunting.
Free forever: three photo-logged meals a day, no card required. New accounts start with 14 days unlimited.
Built for keto dieters, by keto dieters. No generic calorie counting. Every screen answers the one question that matters: "Will this food keep me in ketosis?"
THE KETOSIS BATTERY
A 0-100 indicator showing how likely you are to be in ketosis based on what you've eaten today. No more guessing whether that meal knocked you out of ketosis - you see where you stand at a glance.
HIDDEN CARB DETECTION
KetoLens flags the sneaky carbs hiding in sauces, dressings, breading, glazes, and root vegetables - the ones that quietly kick you out of ketosis without you noticing. Most carb counters ignore them. We make them the headline.
A KETO CARB COUNTER THAT ACTUALLY COUNTS
Take a photo and AI identifies the food and estimates net carbs, fat, protein, and calories - as honest ranges, never fake precision. It's a net carb counter, macro tracker, and calorie counter in one, tuned for the ketogenic diet instead of generic dieting.
HOW IT WORKS
1. Take a photo of your meal
2. AI estimates net carbs, fat, protein, and calories
3. Your Ketosis Battery updates instantly
4. Keep logging, and Insight cards surface the patterns worth knowing
INSIGHTS FROM DAY ONE
The first few days, KetoLens calibrates to you. Keep logging meals, add a ketone reading when you have one, and Insight cards start surfacing what you'd otherwise miss: the lunch that quietly tanks your Battery, the breakfast that sets up a good day, the day of the week things tend to slip. Useful, not naggy.
FASTER EVERY DAY
Foods you eat often get faster. Scan a label once and it lives in your Pantry; star a meal and it's in Favourites - re-logging tomorrow's coffee takes two taps, not another AI call. Doing keto with a partner or family? Connect and share pantries so every label they scan saves you the scan.
WHY KETOLENS IS DIFFERENT
- Macro ranges, not made-up single values: "8-12g net carbs" is what a photo can honestly tell you.
- Gets smarter: the AI learns from your corrections over time.
- Trust-first: every estimate ships with a confidence level (high / medium / low).
MADE FOR LOW-CARB AND LCHF
Whether you're doing strict keto, LCHF, or just cutting carbs for weight loss, KetoLens keeps net carbs front and centre so you can stay in ketosis and hit your goals.
ALSO IN THE BOX
- Manual food entry for when a photo isn't an option
- Daily net carb, fat, protein, and calorie totals
- Timeline diary of every meal
- Manual ketone entry to calibrate your personal ketosis threshold
PRIVACY
Your photos and meals are yours. We don't sell your data and we don't share it for advertising. Account creation needs an email; everything else is optional.
THE IMPORTANT BIT
KetoLens is not a medical device and doesn't provide medical advice. Estimates are approximations. The Ketosis Battery shows likelihood, not a clinical blood-ketone measurement. Talk to a doctor before starting any restrictive diet.
