Dulce

Features — CGM companion for iPhone & Apple Watch

Focused. Well crafted.

Dulce doesn't try to replace your endo or your CGM. What it does, it does well.

Connect your CGM in under a minute

Sign in with your CGM account and Dulce keeps your glucose up to date in the background — on your phone, your watch and your Lock Screen.

  • Works with scan-based and continuous CGM accounts
  • Automatic minute-by-minute updates
  • Credentials encrypted on your device
  • Dexcom and Nightscout are on the roadmap

Your logbook, in seconds

Logging what you eat, inject or do should be instant. That's why Dulce is designed for quick entries — no tabs, no endless forms.

  • Carbs, insulin (bolus and basal), exercise, notes
  • Quick timestamps: now, 15 min ago, 1 h ago, custom
  • Filterable history: today, last 7, 14 or 30 days

Understand your patterns

Trends matter more than any single reading. Dulce shows you the full picture across 7, 14, 30 or 90 days — including what happens in the morning, afternoon and night.

  • Time in range (TIR) against your personal goal
  • GMI (estimated A1C)
  • Time-of-day analysis
  • Overlay curves to compare days

Share only what you choose

Invite your partner, your mother or your endocrinologist. They can see your glucose in real time, get alerts, or both — you decide. You can revoke access anytime.

  • Invite by link — no accounts to create
  • Followers see your glucose live and get alerts
  • They can send you a nudge; you reply "I'm OK" with one tap
  • Revoke access anytime

Your glucose on your wrist

Dulce ships with an Apple Watch app and complications that show your latest reading without pulling out your phone. If data is stale, you'll see it clearly — never a misleading number.

  • Native Apple Watch app
  • Watch face complications
  • Safe mode when data hasn't refreshed in over 15 min

Privacy by default

Dulce is designed to process your data on your device whenever possible. CGM credentials are stored in the system's secure keychain. We don't sell your data — full stop.

  • Credentials encrypted with Keychain (iOS) / Keystore (Android)
  • Health data stored locally by default
  • No ads, no third-party tracking
  • GDPR-compliant
