This week's coach decision
One system. Train. Fuel. Adapt.
Built in the open with real lifters · 14-day free trial
Not three apps to juggle. One coach that makes the calls.
Open the app to one screen: where your weight's heading, today's calorie and protein target, the exact session to train with loads to beat, and one clear call from your coach. No dashboard to interpret.
Every check-in, the coach reviews your training, nutrition, body weight and recovery, then gives you a verdict: keep, adjust, add, remove. Calories, sets and training days, all changed and applied in one tap, or start the next week.
Your goal, your experience, the lifts you love, the ones you'll never do again, your injuries, your schedule. Tell it once. It plans around all of it, and keeps doing so as things change.
Chat with your AI coach to set realistic goals and get a strategy built around your life.
Upload progress photos for an AI body-composition estimate and suggested next steps. Estimates only, not a medical measurement.
Get a personalized program matched to your goals, experience, and equipment.
Adaptive coaching that adjusts your plan based on how the week actually went.

Here's exactly what your coach does with a real target - from day one to the first adjustment.
You set the goal
“I want to lean bulk without putting on much fat.”
Your coach builds the plan
2,850
kcal / day
170g
protein
5
training days
+0.2kg
per week
Three weeks later
Weight is up +0.3kg total - you're gaining, but slower than the +0.6kg the plan expected by now.
Your coach makes the call
“Your gain has stalled below target. I'm adding 150 kcal/day to get you back to +0.2kg/week. Training stays as is - it's working.”
New plan, one tap to apply
3,000 kcal / day
Target rate restored
That loop runs every week you check in - across calories, volume, progression, recovery and phase.
The Fuel & Forge Intelligence Layer
Nutrition intelligence, training intelligence, memory and long-term phase management - working as a single system, not four separate features.
01
Turns your week of data into explicit decisions - not charts to interpret. Every number becomes a clear "here's what changes, and why".
02
Explains what actually happened this week - what worked, what stalled, what the coach is reacting to - before it touches your plan.
03
Calories, training volume, progression, recovery and phase - all adjusted together and cross-checked so the changes don't fight each other. You approve in one tap.
04
Remembers your preferences, your injuries, the lifts you avoid, and every decision it's made before - so guidance stays consistent instead of resetting each week.
05
Shows where you're going, not just where you've been. Your coach manages the whole arc - bulk, cut, maintenance - and tells you when a phase is done and what should come next.
Example. Your coach picks the next phase from your body-fat range, rate of progress and goal.
It isn't tracking your fitness. It's managing your physique over years - one phase at a time.
Every answer you give becomes a real, structured week of training.
Build muscle, lose fat, or get stronger - you choose the direction.
Beginner, intermediate, or advanced - the plan matches where you are.
3 days a week or 6 - your schedule sets the structure.
Every answer becomes a real program, tuned to you.
During every session
A target for every set
Before you even start a set, you see exactly what to hit - no mental math against last week's notebook.
Live, set-by-set feedback
Each set is checked against that target and your last session on this exact exercise the moment you log it.
Adapts if you swap an exercise
Sub one movement for another mid-session and your coach keeps up - targets and future programming adjust with it.
Small decisions. Smarter guidance. Real progress.
AI that turns nutrition into something simple and actionable.
Your workouts, calories, and weekly coaching in one adaptive system.

No. You answer a few questions in onboarding and the coach builds the whole plan: calories, protein, and a full training program. From then on it tells you what to do each day.
Those are logbooks. They show you numbers and leave the decisions to you. Fuel & Forge makes the decisions: it reads your week and changes your calories, volume and training itself, then asks you to approve it.
Every check-in it produces a verdict (keep, adjust, add, remove) across nutrition and training, cross-checked so the changes don't fight each other. Nothing changes until you tap apply.
Yes. Barcode scanning, meal and workout logging, manual target edits and your own routines are all there. The coach works with whatever you log.
