Fuel8

Your account

Your diary on the web, when you say so.

The updated setup starts with Sign in with Apple. Your record-sync choice stays separate. Choose sync when you want your records somewhere you can read them in a browser, share them with a coach, or remove them through your account controls.

Screens show Fuel8 4.2 with sample records, currently in TestFlight ahead of App Store review.

Settings, with the row Account, Sync & Coaching: sign in, sync and coaching, above the daily targets.

Three steps, and two of them are switches.

  1. 01

    Sign in

    The updated setup starts with Sign in with Apple. In earlier versions, open Settings, then Account, Sync & Coaching. You can hide your Apple email and edit optional contact details afterwards.

  2. 02

    Turn on sync

    The switch is called Send my records to my account. It is off until you flip it, and signing in on its own sends nothing.

  3. 03

    Read it here

    Sign in on this site with the same Apple Account and open Progress, Diary or Workouts. The numbers are the app's numbers.

Weekly progress: 1,940 kcal a day across five logged days, water averages and a dash where no sleep has been recorded.

What the website shows you.

Your diary, Progress and workouts use the same recorded values shown to a connected coach. You can also read the raw documents, and the button that removes them.

Progress

A week or month of nutrition, sleep, water and completed workouts, with available shared Health activity. Weight uses the same seven-day weighted average as the app; longer charts label their own date ranges.

Diary

Any day, by meal. Every item with grams, calories and macros, how it was logged and whether it was estimated. Water, sleep, weight and the day's workouts beside it.

Workouts

Every session: each exercise, its sets, reps and weight, the volume lifted, and cardio with distance.

Your data on the server

Every diary document the app sent, listed by name with its size and date. Open a document to inspect it, or use the account controls to remove saved data. Progress photos have their own library and deletion controls.

What sync sends, and what it never does.

Diary sync sends records to your Fuel8 account at www.getfuel8.com for you and authorised coaches to review. Progress-photo uploads have separate controls. Your records are not sold or used for advertising or model training.

Sent while sync is on

  • Your food and water diary, by day
  • Hours slept, from the morning check-in
  • Weigh-ins
  • Targets and profile
  • Saved plates
  • Workout routines and completed sessions

Not included in diary sync

  • Photo files: progress photos use a separate, explicit upload
  • Keys saved by earlier app versions
  • Steps and active energy, unless you turn on that second switch
  • New diary documents while diary sync is off

Progress photos are a separate library. Add a photo, review its date, pose and crop, then choose Only me or named coach recipients before saving. Leaving diary sync off does not prevent an explicit photo upload.

Turning it off

Flip the switch and the app stops sending. What is already on the server stays until you remove it, on the account page, one document at a time or all at once.

Deleting the account

In the app or on the site. It removes the account, every synced record and every coaching link, and tells Apple to stop listing Fuel8 under your Apple Account. Your phone is untouched.

Sharing it with a coach.

A coach gives you a code. Enter it under Connect with a coach in the app, or in the Coaching box on your web account. They can then see your Progress, Diary and Workouts until you press Stop sharing. Their name is listed there for as long as they have access.

A coach can send a workout to your app’s inbox. You add it or dismiss it, and receiving one does not turn sync on. What a coach sees, in full.

The switch is in the app.
