Carb tracking got complicated. It didn’t have to.
Cluttered, noisy apps
Feeds, streaks, badges, challenges — everything except a fast way to log what you actually ate.
Endless upsell nags
Every tap interrupted by a paywall prompt. Logging a meal shouldn’t feel like dodging a sales pitch.
Wrong food data
Crowd-sourced entries that don’t match the label. One bad number and the whole log stops being trustworthy.
Twenty seconds, start to finish.
Say it
“Two eggs and a slice of cheddar.” Type it or say it — whatever’s faster.
Verified
Matched against the USDA database. Real lab numbers, never a guess.
Logged
Net carbs added to today’s ring. Twenty seconds, start to finish.
“The AI reads your meal — it never invents the numbers. The database does the math.”
| TwentyGrams | Most other trackers |
|---|---|
| The AI only reads what you said you ate. | Guesses nutrition from a photo or a crowd-sourced entry. |
| The database does the math, every time. | Numbers vary depending on who submitted the entry. |
| One number: net carbs. Always visible, always the point. | A dozen metrics competing for your attention. |
| Free logging, forever. | Core features gated behind a subscription. |
The tracker that doesn’t make you feel bad.
No shame for an off day, no red numbers, no noise competing with the one thing you came here to track.
Amber, never red.
Going over your goal shows as amber with a plain label — “23g · 3 over” — never a warning. Tomorrow is a fresh ring.
No streaks to break
A day you didn’t log isn’t a broken streak. It’s just tomorrow.
No badges, no leaderboard
No one is watching your numbers but you.
No guilt-trip notifications
The app never shames you into opening it.
Watching your blood sugar too?
Net carbs matter just as much for blood-sugar awareness as they do for keto. Premium adds a metabolic layer built on the same principle as the rest of the app: it logs and shows — it never interprets.
Your meals on your glucose curvePremium
TwentyGrams reads glucose data you already share with Apple Health and lays your logged meals over it — side by side, time-aligned. It shows the picture; it never scores, grades, or interprets it.
A metabolic logbookPremium
Lab results, your own doctor’s target ranges, a symptom journal, medication timing — logged and charted next to your meals. The app never generates a number you didn’t enter.
A doctor-friendly exportPremium
Your logged history as a clean PDF summary you can bring to your next appointment — built for the conversation, not to replace it.
TwentyGrams is a food-logging tool, not a medical device — it doesn’t diagnose or interpret readings.

Frequently asked
What are net carbs?
Net carbs are total carbohydrates minus fiber (and, for some methods, sugar alcohols). Fiber isn’t digested the same way as other carbs, so subtracting it gives a closer estimate of the carbs that actually affect you. TwentyGrams always computes this from the database — never from a guess.
Is TwentyGrams really free?
Yes. The full logging loop — voice and text logging, search, barcode scanning, your history — is free forever, and nothing that is free today ever moves behind the paywall. Premium is a separate, optional layer for people who want the glucose overlay, the metabolic logbook, daily coaching, or trend charts; it doesn’t gate anything in the core app.
How accurate is the food database?
Whole foods (eggs, meat, vegetables, dairy) are matched against USDA lab-analyzed data. Packaged and branded foods come from Open Food Facts, a large crowd-verified database. The AI only extracts what you said you ate — it never invents a nutrition number.
Does TwentyGrams work offline?
Yes. The food database lives on your device, so search and logging work without a connection. Nothing about the core logging loop depends on a server.
Can I use TwentyGrams if I’m managing blood sugar, not just keto?
Many people tracking net carbs for blood-sugar awareness find the same fast logging useful. TwentyGrams is a food-logging tool, not a medical device — it doesn’t diagnose, interpret readings, or replace guidance from your doctor.
Does TwentyGrams interpret my glucose or lab results?
No — and that’s deliberate. Premium can lay your meals over glucose data you already share with Apple Health, and the metabolic logbook charts lab results, symptoms, and medication timing. But the app only logs and displays: it never scores a meal against your glucose, never flags a value as high or low on its own (any target range shown is one you entered from your doctor), and never generates a number you didn’t enter.
When is Premium coming?
Premium launches together with the app — the glucose overlay, metabolic logbook, trends, Audit My Day coaching, fasting insights, and the doctor export all ship as one launch. There’s no purchase path on this page and no pre-orders. Join the waitlist and we’ll let you know when it ships.
