Log your meals. Track your glucose. Build healthy habits

Build a personal history of meals, nutrition estimates, and glucose readings. Start with a photo, manually add readings you already have, and look back over time as your records grow.

  • Photo-first meal journal
  • Manually add existing readings
  • Look back across days

More than one meal. A history you can return to

A photo gets you started. Keeping meals, nutrition estimates, and existing readings together makes your journal useful when you come back days or weeks later.

Typical food logging

  • Searching for ingredients slows you down in the moment.
  • Food logs and glucose readings live in separate places.
  • Too much effort means people soon stop tracking.

With GluNudge

  • Start with a meal photo instead of a search.
  • Get estimated foods, calories, and macro grams in moments.
  • Build a meal-and-glucose history you can revisit over time.

Everyday meal management, one record at a time

Keep meals, nutrition estimates, and recorded readings together. Revisit different days to see your own history, without connecting a glucose device.

  • Manually add an existing reading

    Enter a glucose reading you already have and the time it was taken. GluNudge suggests a meal to link it to, which you can change anytime.

  • Look back at saved records

    When readings are available around a meal, see them on a chart with the meal time marked. This is a view of saved records, not a live feed.

  • Apple Health is optional

    With your permission, GluNudge can also read existing glucose entries from Apple Health as an additional source.

  • Look back over time

    Browse saved meals and readings across days, weeks, and months. Gaps remain gaps: days without entries stay empty.

Recorded readings, not predictions. GluNudge does not measure, estimate, or predict glucose.

Start with one meal and a reading you already have. No device connection or Apple Health access required.

  1. 01

    Snap a meal

    Take or choose a meal photo. AI estimates the visible foods, calories, and macro grams. These are estimates, not measurements.

  2. 02

    Manually add a reading

    Enter a glucose reading you already have, along with the time it was taken. You don’t need a new measurement to try the app.

  3. 03

    Look back across days

    Return to saved meal photos, nutrition estimates, and readings from different days. Missing entries stay missing.

Simple logging, clear limits

Your meal history stays on your device unless you turn on iCloud sync. Photos leave your device only when you ask for AI analysis or a Meal Recap, and every nutrition result is an estimate.

Private by default

Meals and readings stay on your device, or in your private iCloud account if you turn on sync. Photos you send for analysis are stored only temporarily.

Lifestyle awareness

GluNudge helps you understand everyday meals. It does not provide diagnosis, treatment, or medical guidance.

Recorded readings, not predictions

GluNudge shows readings you enter manually, with optional access to existing Apple Health entries. It does not measure, estimate, or predict glucose.

Is GluNudge free?

GluNudge is free to download, and so is meal and glucose logging. GluNudge Plus is an optional subscription that adds longer-range glucose reports and AI meal analysis for every new meal. Prices and any trial offers are shown in the App Store before you subscribe, and you can cancel anytime.

How accurate are the meal estimates?

The estimates are best-effort, based on what is visible in the meal photo and reasonable assumptions about ingredients and portions.

Does GluNudge measure or predict glucose?

No. GluNudge organizes the glucose readings you record alongside your meals. It does not measure, estimate, or predict glucose.

Where do my glucose readings come from?

You manually enter readings you already have, along with the time they were taken. With your permission, GluNudge can also read existing entries from Apple Health as an optional source. You can change which meal a reading is linked to.

Does GluNudge connect to a CGM?

No. GluNudge does not connect to CGM devices or automatically sync sensor data. No real-time glucose monitoring is provided. Optional access to existing Apple Health entries is not a CGM integration. You can use the app by photographing meals and manually entering readings you already have.

Is my meal data private?

Your meal history and readings stay on your device by default. If you turn on iCloud sync, they are stored in your private iCloud account. Meal photos are sent to GluNudge only when you request AI analysis or a Meal Recap, and are stored temporarily under our retention policy.
