Blood sugar & glucose tracker

AI Analysis explains your readings instantly, set medication or reading-time reminders, and share a clean PDF with your doctor. Everything stays on your phone.
Kan Şekerim is a blood glucose diary that keeps your readings where they belong: on your phone.
No account. No sign-up. No server. Your measurements are stored in your device's local storage and are never uploaded to us — which also means there is no database of your health records for anyone to breach.
LOG IN SECONDS
Pick fasting or post-meal, type the number, save. That's it. Add a short note if you want to remember what you ate or how you felt.
SEE WHERE YOU STAND
Every reading is labelled against general reference ranges, with separate thresholds for fasting and post-meal values — because 120 mg/dL does not mean the same thing before and after a meal. Seven-day averages sit right under your latest reading.
A CHART THAT DOESN'T MIX THINGS UP
Fasting and post-meal readings are drawn with different shapes, not just different colours, so the two stay distinguishable — even on a black-and-white printout. The scale stays fixed, so this week's chart can actually be compared with last week's.
BUILT FOR THE DOCTOR'S VISIT
One tap turns your log into a dashboard PDF, or exports it as a CSV spreadsheet. The file is named by date, so what lands in your doctor's inbox is Kan-Sekerim-2026-08-08.pdf, not a random string. Print colours are tuned separately from the screen theme so the report is actually readable on paper.
MG/DL OR MMOL/L
Both units are supported and switch instantly. The app picks a sensible default from your device region and you can change it any time.
SIX LANGUAGES
Turkish, English, German, Spanish, Portuguese and Arabic, with a right-to-left layout for Arabic.
WORKS OFFLINE
There is no network dependency for anything except ads. Log a reading on a plane, in a basement, anywhere.

Kan Şekerim is a logging tool. It does not diagnose, does not recommend treatment, and does not suggest medication or doses. The reference ranges it displays are general ones and are not a substitute for the personal targets your doctor sets for you. Always make decisions about your health together with your doctor.
The app is free and supported by banner ads. On iOS you are asked before the advertising identifier is used — decline and ads simply stop being personalised; no feature is withheld. In the EU and UK you choose your ad preferences before any ad loads, and can change them later in Settings.
