The same data, in five places, talking to each other.
Every other nutrition app ignores your training. Rebel Fuel starts there. Your session sets the target. Tracking, fasting, recipes, and supplements stay locked to it. Built for endurance and hybrid athletes.
Today's session sets your fuel. Extra carbs to refill glycogen on hard days, steady on rest days. No other tracker does this.
Macro targets that flex with training, plus Snap Meal, photo your plate, get macros in 3 seconds. No database scrolling.
Eating-window tracking and daily hydration targets. The timing and fluids your macros need to land.
Your full protocol in one place. What you take, when, and why.
Macro-matched meals, suggested by training day. Save your own or use ours.
The Training module pulls your planned sessions directly from your calendar so you always know what's on deck, without digging through tabs. Your readiness score sits right next to it, so you go into every session with full context.
Training doesn't live in isolation. When your recovery is low, you see it right next to your session, so you can make an informed call rather than grinding through.
Your session, your readiness, your decision, all on one screen.
The Nutrition module gives you two things: clarity on your macro targets, and a frictionless way to log what you eat. Cal AI turns your camera into a macro scanner, point it at any meal and get calories, protein, carbs, and fat in seconds. One tap to log.
Point your camera at any meal, plate, bowl, snack, or drink. No barcodes. No food database search.
AI identifies the food and returns estimated kcal, protein, carbs, fat, plus a food quality signal based on your training phase.
One tap to log. Macros update instantly. Remaining targets recalculate so you always know where you stand.
Nutrition is where most performance systems fall flat, they either track everything obsessively or nothing at all. Rebel Fuel takes the middle path: clear targets + one-tap logging. Know your numbers, log without friction, let the Recipes module handle the rest.
Snap it. Log it. Know your numbers. No spreadsheets, no manual entry, no excuses.
Generic diet apps assume you sit still. Rebel Fuel assumes you train , and adjusts. Log a hard session and your target moves up to match the work; on a rest day it settles back. Endurance or hybrid, you fuel for the day you're in.
Generic trackers ignore your training entirely. Rebel Fuel starts there, because what you should eat today depends on what you did today.
Fuel the work in front of you, today, not on average.
Your supplement protocol is a system, specific compounds, specific timing, specific doses. Supplement Stack treats it that way instead of burying it in notes or relying on memory.
When you're consistent with your training, your recovery, and your nutrition, supplements become the edge. Supplement Stack makes sure that edge is intentional and not random.
Your stack, organized. No guesswork about what to take or when.
Rebel Fuel closes the loop between nutrition targets and actual food. The Recipes module suggests meals that match your macros for the day, accounting for your training load and what you've already eaten.
The goal isn't perfection. It's having a solid answer to "what should I eat today?" that fits your numbers, without spending 20 minutes figuring it out.
Macro-matched meals for every training day. No meal prep anxiety.
Your food reads your training. A hard session bumps tonight’s target and tilts your recipe picks toward carbs. Remaining macros at 14:00 shape what gets suggested for dinner. One loop, not two apps stitched together.
Recipe suggestions read your training-day context and remaining macros. Hard day surfaces carb-forward meals. Rest day surfaces fat-adapted defaults.
Recipe picks match your remaining macros for the day, not a generic meal plan. The Salmon + sweet potato example above is real Snap Meal logic.
Your day’s session adds fuel to your target automatically , so being “under your goal” on a big training day doesn’t mean you under-ate.
Stack consistency is tracked alongside your fuel. When you ask the Coach about your supplements, the gap is in the context.
Rebel Fuel is open to every tier. Tracking, fasting, recipes, and supplements work the same on the 7-day free trial and on Pro+. The AI features (Snap Meal, macro estimation, coach chat) come with the trial and stay unlimited on Pro+.
