App guidance is included with the active Complete Meals plan described in your offer. It is part of the solution: the food provides the planned portions, and the app helps you use them consistently.
Check the access instructions provided with your purchase. You do not need to buy a separate digital keto or fasting plan to understand this food routine. If you already have a separate Best.me digital purchase, its billing and access may be governed by different terms.
If you see an app charge you do not recognize, contact us with the purchase email and charge details so we can identify it before you buy anything again.
