Kan Şekerim

A blood glucose diary for iOS that keeps every reading on the phone. Log a measurement in three taps, see where you stand, and hand your doctor a clean PDF instead of a notebook.

Nothing leaves the phone

Readings live in local storage only — no account, no backend, no analytics. The app works fully offline, which also means there is no database of health records to breach.

Six languages, one binary

Turkish, English, German, Spanish, Portuguese and Arabic, including a right-to-left layout. Language and unit (mg/dL or mmol/L) are detected from the device and stay overridable.

Built for the doctor's visit

One tap turns the log into a dashboard PDF or a CSV file. Print colours are a separate palette from the screen theme, because the on-screen mint tones drop to 2.3:1 contrast on paper.

Fasting and post-meal, never mixed

The two reading types have different clinical thresholds, so the chart separates them by shape as well as colour — readable even when printed in black and white.

A health app that collects no health data

  • Glucose readings are written to the device's local storage and nowhere else — there is no server to send them to.
  • On iOS the app asks before touching the advertising identifier. Decline and the ads simply stop being personalised; nothing in the app is withheld.
  • EU and UK users get Google's consent screen before any ad loads, and can change that choice later from the app's settings.
  • Exports are user-initiated: the PDF or CSV goes wherever you send it, and only then.

The app is a logging tool — it does not diagnose or give medical advice, and the reference ranges it shows are general ones rather than the personal targets a doctor sets. Full details are in the privacy policy.
