1

Set a goal you can actually reach

Pick a goal weight and a pace, and Rackfuel shows the finish line move as you choose: lose faster, arrive sooner, but it warns you when a pace is too aggressive to hold, and it refuses targets below a safe floor outright.

  • A goal weight, a pace, and an honest arrival estimate
  • Progress lives at the top of its own tab: how far you have come, how far is left
  • Unsafe targets are refused, not just discouraged

Get stronger, and see it

Log sets with last time's numbers beside every one, and your personal bests sit on Progress where you can watch them climb. Getting stronger stops being a feeling and becomes a number with your name on it.

  • Last time's weight and reps beside every set
  • A rest timer under the set that earned it, and on your lock screen with the next set spelled out
  • Personal bests per lift, plus charts and records for every exercise
  • Forgot your phone? Edit any past workout: date, time, sets, all of it
  • Over 800 exercises, plus any you create

Stay on it

Every day you log anything, the streak grows and the day's ring closes. Earn a badge and the app stops to hand it to you. A missed day is absence, not failure, and nothing ever rewards eating less.

  • A streak you can see from the home screen
  • Day rings: green when the day went to plan, gold when it went a little over, red only when it went far
  • Twenty-six badges, each earned by showing up

Trust the number you are chasing

Most apps guess your calorie target once and never check it. Rackfuel compares what you log with how your weight actually moves, and within a couple of weeks your target comes from your own body, not a formula. When your logging is too patchy to trust, it says so.

  • Your measured burn, not a textbook estimate
  • Every number shows its working
  • Log food by barcode, label, photo, search or typing it in

The rest of it

The parts you only notice when they are missing

A tracker earns its place in the small moments: the meal you eat every Tuesday, the photo you take once a month, the session your phone slept through.

Meals you keep

Save a plate you eat often and log it again in one tap, filed under the meal it belongs to.

An eating window

Daily intermittent fasting, counted honestly. Your targets do not change; a fast decides when you eat, not how much.

Progress photos

Taken with a weigh-in and kept on your device, with any two side by side when you want to see the difference.

The tape as well as the scale

Chest, waist, hips, arms and thighs, to the tenth, because the scale is not the only thing that moves.

Reminders you set

One per meal, at the times you actually eat, capped at one a day each. Silence is always an option.

A workout that survives

Close the app mid-session, or lose it to a crash, and the workout is still there when you come back, rest timer included.

Milestones

The trophy room

Consistency, strength, training and progress, each with its own badges. Locked ones show what is coming, and the weight milestones only count for people with weight to lose.

The honest comparison

One app instead of two

Cal AI scans food well but does not log training. Strong logs training well but never asks what you ate. Rackfuel does both, and connects them, which is the only way a calorie target can learn from your training.

FAQ

Fair questions

When can I download it?

Rackfuel is in the final stretch of development and heading to the App Store soon. This page will carry the download link the day it is live.

Which devices does it support?

iPhone, running iOS 26 or later. An Apple Watch companion is planned after launch. There are no plans for Android.

Do I need an account?

No. Your data lives on your device and the app works fully offline apart from photo meal estimates, which need a connection.

How accurate is the photo scanning?

It is an estimate, and Rackfuel is honest about that. Every photo estimate is labelled with its confidence, you can correct it in one tap, and a barcode or label scan is always more accurate when you have the packet.

What happens to my meal photos?

They are sent securely for estimation, processed, and discarded. They are not stored, not used to train models, and never linked to your identity.

Why is the burn engine a paid feature?

The engine is what turns logging into answers, and its photo pipeline costs real money to run. The free tier is genuinely useful forever; Pro pays for the parts that cost us per use, at a price that undercuts the apps that do half of this.

Does the rest timer work with the phone in my pocket?

Yes. The timer lives on your lock screen for the whole workout, with a Skip button and the next set written out, and the bell rings even with the phone on silent. Pick from five sounds, each with a matching haptic, or turn the sound off entirely.

Is this suitable for everyone?

Rackfuel is a tracking tool, not medical advice, and it is built to be on your side. It refuses calorie targets below a safe floor and will not aim at an underweight goal. A day slightly over target shows in gold, not red; red is kept for genuinely far over. The streak forgives one missed day a week, because life happens. The quotes never guilt, reminders cap at one per day at a time you chose, and a photo estimate is never written to Apple Health until you confirm it. If you have a history of disordered eating, please speak to a professional before using any calorie tracker.
