Track, understand, and share your glucose — quick logging, Apple Health sync, smart insights, and beautiful reports.
GlucoLens helps you understand your glucose, not just record it.
LOG IN SECONDS
Quick manual entry with meal context (fasting, pre/post-meal, bedtime), tags, and notes. Smart suggestions pick the likely meal context for you.
SEE THE FULL PICTURE
Interactive charts with your target range, time-in-range breakdowns, daily averages, and trend arrows. Works beautifully with CGM-scale data imported from Apple Health.
APPLE HEALTH & CGM
Two-way HealthKit sync: import readings from CGMs and other apps, write manual entries back, with automatic duplicate protection.
UNDERSTAND YOUR PATTERNS
On-device Smart Insights surface patterns from your own data — best time of day, meal impact, weekend vs weekday — always labeled as informational, never medical advice.
A1C & GMI ESTIMATES
Research-based estimates from your last 90 days of readings, clearly marked as estimates and gated until enough data is available.
EVERYWHERE YOU LOOK
Home screen and lock screen widgets (latest reading, sparkline trend, time in range), iCloud sync across your devices, and full support for English, Spanish, and Portuguese.
YOUR DATA, YOURS
Readings live in your private iCloud database. Export everything as CSV or a polished PDF report for your care team. Delete your account and data at any time.
GLUCOLENS PRO
Upgrade for unlimited history, advanced statistics, and professional exports.
