Insulin resistance usually arrives a decade before anyone measures it.

40%
of US adults aged 18 to 44 are insulin resistant, by HOMA-IR (NHANES 2021)
26.5%
of adults worldwide, roughly one in four people
80%
of people with insulin resistance have never been diagnosed
How it works

Five habits, tracked daily. One keeps the streak alive.

These are the levers with real evidence behind them for lowering fasting insulin. Log a single one and your streak holds, because a bad day should not wipe out a good month. Get four and Biscuit calls it a perfect day.

01
Kept it low-GI today
Skipping the fast carbs means less insulin production
02
Walked after a meal
Ten minutes pulls glucose into muscle without insulin
03
Got seven or more hours last night
Two short nights measurably raise insulin resistance
04
Stayed well hydrated
Dehydration worsens insulin sensitivity
05
Respected my eating window
An overnight break gives insulin time to fall
What is in the app

Free where it should be free.

Habit tracking, the science, and the tools that need no AI cost nothing. The features that run on AI are part of Premium.

Premium

Meal scanner

Photograph a meal or describe it. Biscuit returns a spike score out of 100, the macros, and one specific tip. Photos are analysed and discarded immediately, never stored.

Premium

Weekly meal plan

Seven days built around your numbers, your eating window, your dietary restrictions and your calorie target, with a spike score on every meal.

Free

HOMA-IR calculator

Enter fasting insulin and glucose, or your A1C, and get the number your doctor would calculate, with reference ranges in plain language.

Free

Fasting timer

A live countdown for a 16:8 or 18:6 window. Start it, and Biscuit tracks the fast and logs it against your habits.

Free

Symptom check and Learn

Seven questions drawn from clinical research give a risk picture with no blood test. The Learn tab covers the science with sources you can follow.

Premium

Weekly review

A Sunday check-in and report on whether energy, cravings, sleep and mood are actually moving, plus your lab results tracked over time.

Your data

Health data is the most personal data there is.

  • Meal photos are analysed, then discarded. Never stored.
  • Your health numbers are never sold or shared with advertisers.
  • No advertising trackers, pixels, or data brokers.

  • Data stored in Canada, encrypted in transit and at rest.
  • Anthropic does not train its models on your data.

Biscuit is not a medical device

Biscuit is a wellness and education app. It does not diagnose, treat, cure or prevent any disease. Spike scores, HOMA-IR values, metabolic age and every AI response are educational estimates, not medical advice. Talk to a qualified healthcare professional before changing your diet, exercise or medication. In an emergency, call your local emergency number.
