An AI that reads your patterns.
Ask CarbLens sees your meals, your doses, and your curves. It learns everything about your blood sugar, which can be very helpful!
It will never tell you how many units to take. Ever. It exists so you walk into your next endo appointment with better questions.
Illustrative exchange. That last line is real. It’s required on every answer that reads your numbers.
Diabetes is less lonely with your crew!
See when your friends log meals, see their scores, and be there for them with their TIR! The fastest way to grow is together, with support. Friends and group chats help make the game fun.

FAQs
What does CarbLens do?
Turns every meal into a score. Snap it, log your dose, and three hours later you know exactly how it went. No more guessing, no more spreadsheets, no more wondering why you were 240 at 4pm.
Will it actually improve my numbers?
It shows you the pattern you keep missing. Angel's time in range went up 28–30% in three days. Ian went from 73% to 92%. Your results are yours, but the next right move stops being a mystery.
What's a play?
Your daily mission. The app finds the hours that get you and hands you one goal: keep 3–6pm in range, +500 XP. Beat it and you watch your own number move.
What does the AI do?
Reads your food from a photo. Reads your patterns over weeks: the meals, times, and doses that send you high or low. Then it tells you, in plain words, the things you'd never notice on your own.
Is it actually fun?
Every good meal is a win you collect. XP, levels, streaks, bosses, leaderboards. Managing diabetes finally has a scoreboard, and for once you're the one winning.
Can I play with friends?
Battle on time in range, climb the leaderboard, share your live glucose, and hang in the feed with people who actually get it. Nobody sees anything you don't choose to share.
Which CGMs work?
Dexcom and FreeStyle Libre. No CGM yet? Scans, the journal, the AI, and friends all still work.
Does it tell me how much insulin to take?
No. It shows what you ate, what you dosed, and what happened. Dosing stays between you and your care team.
What does it cost?
Free to download, premium inside, and the yearly plan starts with a 3-day free trial.
How do I cancel or delete my account?
Cancel from iPhone Settings → Apple ID → Subscriptions. Delete your account from the app's Settings and your data is removed from our servers.
Is this carblens.com, carblens.app or carblens.org?
No. This is CarbLens AI, the iPhone app by Viral Builders that pairs your meals with your real CGM curve. Other products share the name; see our comparison.

Stop guessing.
Snap a meal, watch the curve, rack up wins with your crew.
