kerntrack: Calories & GLP-1
Calorie counter, macro tracker
Only for iPhone
Free · In‑App Purchases
iPhone
Free: calories, macros, the barcode scanner, your own meals and drinks in ml. In the COACH tier you also log injections, side effects and protein.
kerntrack is a calorie counter and food diary for everyday life in Germany: log calories and macros, scan barcodes, track your weight. The COACH tier adds a GLP-1 companion and an intermittent fasting timer.
Important: kerntrack is not a medical device. It does not diagnose, treat, cure or prevent any disease, and it is not a substitute for advice from your doctor or dietitian. Calorie and nutrition figures are estimates. Talk to a healthcare professional before changing how you eat, particularly if you are pregnant or breastfeeding, live with diabetes, have a history of disordered eating, or take prescription medication.

GLP-1 COMPANION (COACH tier)
Record every injection with its dose and site, and see the last site you used at a glance. Note side effects day by day on a simple 0 to 5 scale, tag the foods you tolerated well and the ones you did not, and keep an eye on your protein. Set a reminder for injection day, with neutral lock screen text if you prefer.
kerntrack reminds and documents. It makes no treatment decisions and does not replace medical advice.

YOUR DATA
Your nutrition and health data lives on your iPhone, not on our servers and not in your iCloud backup. What leaves your iPhone, you send yourself: the encrypted backup, a report for your doctor, or a meal photo for recognition. Photo recognition uses an external service, and the app asks your permission first. An account is optional and only needed to subscribe.
Back everything up yourself as a password-encrypted file that only you can open, and restore it on a new phone. We never see that file, and we cannot recover it or your password if you lose them.
Open Food Facts search, barcode lookup, photo recognition and Oura sync need a connection. Your own foods, saved meals, water tracking and the German reference foods work without one.
SUBSCRIPTIONS AND PRICES
kerntrack is free. PRO and COACH are subscriptions, monthly or yearly. If your Apple Account has never had a kerntrack subscription, the first month is free. After that you pay the price the app shows before you buy, through your Apple Account. A subscription renews automatically unless you cancel it at least 24 hours before the end of the current period. You can cancel at any time in your Apple Account settings under Subscriptions. Calorie and macro tracking and the barcode scanner stay free.
