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.

Real example
Fage Total 0% Plain Greek Yogurt (per 100g)
Manufacturer’s label
3.0g
Independent database
4.1g
Relative gap
~37%
Same yogurt, same 100g — a ~37% gap between the manufacturer’s own label and one independent database. That’s the kind of drift a provenance line is supposed to catch.
It tells you the truth — without the theater.
It states the number and the trend. No verdicts, no cheerleading, no red alarms — an instrument doesn’t have opinions about your day, it just shows you where you stand.
This week
State, not scorekeeping.
Ketosis is a multi-day state, not a daily pass or fail. You see your 7-day trajectory, so a single day over is just one point on a line — never a failure. Over your goal shows amber, never red: it’s information, not an alarm.
No streaks to chase
An instrument doesn’t gamify. A day you didn’t log isn’t a broken streak — it’s just tomorrow.
No badges, no leaderboard
Nothing to win, no one to beat. The only number that matters is yours.
No guilt-trip notifications
It reports conditions, not judgments — and never nags 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 curve — coming with PremiumPremium
Planned for Premium: reading the glucose data you already share with Apple Health and laying your logged meals over it — side by side, time-aligned. Shown, never scored, graded, or interpreted.
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 — natural-language (typed) logging, search, your history — is free forever, and nothing that is free today ever moves behind the paywall. Premium is a separate, optional layer, launching with the app, for people who want deeper trend windows, a full micronutrient and biometric view alongside their net carbs, and a doctor-ready PDF export; 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. See exactly where our numbers come from →
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 is planned to lay your meals over glucose data you already share with Apple Health, and to chart lab results, symptoms, and medication timing in a metabolic logbook — both launching together with the app, not available today. The design principle carries through either way: the app only logs and displays, it will never score a meal against your glucose, never flag a value as high or low on its own (any target range shown is one you entered from your doctor), and never generate 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.
