The number that matters

net carbs      = total carbohydrate − fiber glycemic load = glycemic index × net carbs / 100

A rice cake has a glycemic index of 82 — high. But one cake carries only about 7 g of net carbs, so its glycemic load is roughly 6 — low. That gap is why load, not index, is the number worth tracking, and why doing it by hand is tedious enough that nobody keeps it up.

Features

Two Taps to Log

The add sheet opens with your most-used and most-recent foods already listed, before you type anything. Adjust servings or delete an entry in one tap; swipe to remove.

Daily Goal Gauge

A gauge shows total glycemic load against your own daily goal, graded green, orange, or red. Every food carries the same colour chip, so the good swaps are obvious at a glance.

Any Day, Not Just Today

A week strip and a date picker let you back-fill days you missed. Day totals cover net carbs, total carbs, fiber, saturated fat, and calories, with a callout for the biggest contributor.

One Searchable Library

Single foods and multi-ingredient meals live in the same list — no guessing where you saved something. Filter by food or meal and by category; sort by name, index, load, or recency.

USDA Database Built In

Around 7,400 foods with their nutrition already filled in, searchable offline. Find the food, pick the serving, done — no typing numbers off a packet, and no network. 59 common foods are pre-loaded.

Scan the Label

Point the camera at a Nutrition Facts panel and it fills in serving size, calories, total carbs, fiber, and saturated fat. The raw recognized text always stays visible so you can fix anything it got wrong. All on-device.

Index Filled In For You

Glycemic index comes from a built-in table of 166 foods with aliases, plus a category estimate when nothing matches. Every value is overridable, and the app always tells you where the number came from.

Meals That Roll Up

Build a meal from foods and say how many servings it makes. Per-serving totals update live, with the glycemic index weighted by net carbs — the way the arithmetic actually works.

Weekly & Monthly Reports

Total and daily-average load, a bar chart with your goal line, per-week summaries, best and highest day, and the share of days within goal. Days you did not log are drawn as gaps, not zeros.

Browse the Reference Table

The whole glycemic index table is searchable from Settings, category estimates included. Help explains index, load, and net carbs in plain language, and why they differ.

CSV Export & Import

Export your foods and your journal as CSV, with net carbs and load already worked out, and import them back. Your records are yours to take anywhere.

Your Settings, Your Sync

Light, dark, or automatic theme. Metric or US serving units. A daily goal with the standard ranges explained. Optional iCloud sync runs through your own private account — off by default.

Why Glycemic Load Tracker?

1

It does the part people give up on

Looking up a glycemic index and multiplying it by net carbs is exactly the friction that kills a tracking habit by day three. Two taps, and it is done.

2

Load, not just index

Index charts rank foods; carb counters count grams. Only load ties the two to the portion you actually ate.

3

Honest about estimates

Every glycemic index shows its source — a reference match, a category estimate, or your own value — so a guess never masquerades as a measurement.

4

Current data, not recycled charts

The reference values come from the 2021 international tables, the peer-reviewed systematic review of studies run to the ISO standard. Watermelon, the food every GI article calls high, was revised down from 76 to 50 in that review — charts still circulating online have the old number.

5

Honest about gaps

Un-journaled days are drawn as gaps, not zeros. A blank day is a hole in the record, not a perfect score. The reports do not flatter you.

6

Genuinely private

No account, no ads, no analytics SDK, no network calls. Health-adjacent data never leaves the device, and the privacy manifest declares zero data collected.

7

Works offline, always

Airplane mode, a basement grocery aisle, a plane — it does not care. The glycemic index lookup, the USDA database, and label scanning all run on your device.

No account. No ads. No tracking.

Your food log stays on your device. Glycemic index lookup and label scanning are entirely on-device, and iCloud sync — if you turn it on — runs through your own private account that we can never see.

Glycemic Load Tracker is free. If it helps you keep the habit, a small tip keeps it going.

Estimates, not medical advice. Published glycemic index values are averages with real measurement error, and they shift with variety, ripeness, processing, and cooking. Glycemic Load Tracker does not diagnose, treat, or dose anything. Talk to a qualified healthcare professional about decisions concerning your health.
