Glucose timeline
Your full CGM history in one chart. CGM readings, manual scans, and spot checks unified with upper/lower reference bands — so you see the full picture.
Local-first · Private · AI-powered
Know your glucose. Understand your body.
GlucoSense turns your FreeStyle Libre CSV exports into deep personal insights — which foods spike you, how exercise helps, and patterns your CGM app never shows you.

Core features
Pattern discovery, not just tracking
CGM apps show you numbers. GlucoSense shows you what those numbers mean for the way you eat, move, and live.
* Requires an existing CGM device and FreeStyle Libre CSV export
Time in Range (TIR)
See TIR %, mean, median, and time above/below your target range. Understand your daily rhythm at a glance without exporting to another app.
Avg rise by food category
Rank your meal categories by average post-meal glucose spike. Pure SQL — no AI credits needed. Know whether ramen or pasta hits you harder.
Exercise impact
See the average glucose change in the 2-hour window after each activity type. Does tennis help more than running? Your data knows.
Blood pressure panel
Import your Omron readings and view SYS/DIA/Pulse over time alongside your glucose. WHO classification bands show you where you stand.
100% local, always
Your data lives in your browser (sql.js + IndexedDB). Nothing is uploaded. The Mac app version (Tauri) keeps it in a local SQLite file you own.
How it works
From CSV to insight in under a minute
01
Export from LibreLink
Open FreeStyle LibreLink on your phone, go to My Account → Reports, and download your CSV. Works with Libre 2 and Libre 3. No API key or account needed.
Also imports: Omron BP CSVs · Apple Health workouts · Manual entries
02
Import in seconds
Drop the file in GlucoSense. The importer auto-detects the format, converts units if needed, and stores everything in a local SQLite database inside your browser.
Re-imports are safe — overlapping periods are replaced, not duplicated.
03
Correlations surface instantly
No waiting. Tier-1 SQL aggregations run immediately on import: food category rankings, hourly baseline, exercise impact, BP trends. All cached for instant loading.
Zero AI calls needed — this is pure local computation.
04
Ask questions in plain English
Bring your own Claude API key and open the chat panel. GlucoSense sends pre-aggregated context — not raw data — so Claude answers fast and stays grounded in your numbers.
Responses are cached by query hash. Force-refresh any time.
