Stacks tracks calories, macronutrients and strength training on iPhone. Questions, problems and feedback can be sent to the email address at the bottom of this page.

Including the device model, the iOS version, and a short description of what happened and what was expected helps in providing a quick answer.

All data can be exported at any time from the app settings. The export contains meals, foods, workouts, body measurements and targets.

The account can be deleted from the app settings. Deletion permanently removes the account and all data associated with it, and cannot be undone.

Should signing in fail, the password reset option on the sign-in screen sends a reset link to the email address registered on the account. If that email does not arrive, checking the spam folder is advised before contacting the address below.
