Terms · updated 28 September 2026
CoreFuel is published by Fittest tech ltd. and distributed through the App Store.
Use of CoreFuel is governed by Apple’s standard End User Licence Agreement, which applies to every app distributed through the App Store unless a custom agreement replaces it.
Every new account begins with 14 free days. That trial is run by CoreFuel, not by Apple, so no card is required and nothing is charged during it.
After the trial, CoreFuel Plus is an auto-renewing monthly subscription, charged to your Apple ID at confirmation of purchase and at the price shown in your own App Store. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in your Apple ID subscription settings; deleting your CoreFuel account does not cancel it.
CoreFuel estimates the nutritional content of food and summarises readings from your phone. It is not a medical device and does not provide medical advice, diagnosis or treatment. Speak to a qualified professional before making decisions about your health.
