About nudg | diabetes companion

nudg: Clarity, Control, and Peace of Mind. Built by a Diabetic for Diabetics Connect Dexcom or Libre directly, or link your Nightscout site — DIY or standard CGM, nudg turns your diabetes data into decisions you can act on. No complex setup. **Live Dashboard** Glucose, trend, and active insulin at a glance, with a smart forecast that accounts for your insulin and carbs — and shows you how accurate it's been. **Dose Calculators, with Guardrails** Quick Bolus, Correction, Meal, and Extended Bolus tools. Unusually large doses are capped and confirmed; stale or low readings trigger warnings before you dose. **Log Everything, Fast** Insulin, carbs, fluids, ketones, weight, exercise, and notes — one tap from the dashboard, your Apple Watch, or Siri. **Hydration, Built for Diabetes** A daily water goal that rises with time spent high, exercise, and sick days — with gentle reminders only when you're behind. **Alerts That Matter** High, low, urgent low, and rapid-change notifications, plus daily basal reminders with one-tap logging. **AI Nutrition** Describe or photograph your meal for a carb estimate in seconds — then get a suggested dose built from your ICR, ISF, current glucose, and any correction needed. **Analytics & Reports** Time in Range, estimated A1c, variability, and sensitivity trends — detailed enough for your doctor, clear enough for you. **Everywhere You Are** Apple Watch app and complications, widgets, Live Activities, Apple Health sync (glucose, insulin, carbs, water, workouts, sleep), fasting timer, supply tracking, and iCloud backup.

What’s new

Version 2.3.6 · Updated October 30, 2026

Share with a caregiver Let family or carers follow your glucose from their own iPhone. Go to Settings > Caregivers, pick someone from your contacts, and choose what they can do: • View only: they see your glucose, graphs, insulin and carbs. • View and log: they can also add carbs, insulin and notes for you. nudg sends them a link by message or email, and nudg sets itself up on their phone when they tap it. Your API secret is never shared: each caregiver gets their own access, which your Nightscout enforces, and you can change it or stop sharing at any time. Works with any Nightscout, hosted on nudg.in or your own. Caregivers can't use the bolus calculators. A fresh look • New nudg icons for Home, Treatments, Journal, Calculators, Fasting and Settings. • A small spinner next to Settings shows when nudg is syncing, then a tick when it's done. It replaces the "Data synced" banner that pushed the dashboard down. • The sync time on the glucose card is shorter and always fits on one line. If nudg can't reach your data, an orange clock shows you're seeing the last sync, not live readings. Fixes & improvements • On iPhones running iOS 26, the dashboard no longer slides up under the top bar. • iPhone Duo: on the closed screen, the glucose card no longer wraps onto extra lines, and the sync status sits in the top bar.
