Running your own account

Updated on 2026-10-16

Your hi.fitness account is yours to run end-to-end - you don't need a trainer.

When you first register you'll be asked to complete a short intake survey before the rest of the app opens. See Completing your intake survey.

In the mobile app

Open More → Settings to change your details on your phone:

  • Profile - your name, phone number and postal address, plus your gender, date of birth and height, which your calorie targets are worked out from.
  • Language - your account language, so the emails we send you switch with the app. It also decides the language of everything the app writes for you, such as the foods it reads back from a spoken meal.
  • Units - metric (kg, cm) or imperial (lb, in). This is an account setting, so it applies on every phone you sign in on.
  • Privacy - the Share usage data switch, which lets us collect information about how you use the app, so we can see what works well and what to improve. It never includes what you type or your photos, and your choice applies on every phone you sign in on. See Sharing usage data.

Your email address is shown there, but it can't be changed at the moment.

Changes that haven't synced

Everything you log in the app (a workout, a meal, your weight or a habit) is saved on your phone first and sent to your account as soon as it can be. With no signal, or if hi.fitness is briefly unavailable, nothing is lost: the app keeps your changes, even if you close it or restart your phone, and sends them when it can reach us again.

If a change still hasn't reached your account after a few hours, or couldn't be saved, Settings shows Unsynced changes at the top, with how many there are. Tap it and choose Try again, or Send to support to share a file with what's waiting, so we can help.

Signing out deletes changes that haven't synced yet. If there are any, the app warns you first - choose Sign out anyway only if you're happy to lose them.
