Stackdd PT

A personal trainer in your pocket.

Stackdd PT is a complete coaching system, powered by AI — one place that tracks your training, food, body and activity, and adapts the plan to you as you go. Not another tracker that does one thing and forgets the rest.

Most apps give you a single piece. A food app logs lunch. A workout app counts reps. A tracker draws a line on a chart. None of them talk to each other, and none of them coach. Stackdd brings it together: one coach, working from the full picture, helping you stay consistent and actually hit your goal.

EVERYTHING IN ONE SYSTEM Training, nutrition, body measurements and daily activity all feed one place. Because it sees everything, the guidance is built on your real history — not generic tips.

TRAINING PLANS THAT ADAPT TO YOU A plan designed around your goal, experience and equipment — then adjusted as you progress. Log weight, reps and RPE set by set, with rest timed for you. 1,376 exercises with demonstrations, swapped in a tap if a machine's taken.

FOOD LOGGING, MACROS THAT MOVE WITH YOU Point your camera at the plate and turn a photo into macros in seconds. Your calorie and protein targets adjust based on your progress and training — heavier week, more fuel; trend stalling, a sensible nudge. Plus recipes built around your numbers.

TRACK YOUR BODY, NOT JUST THE SCALE Weight trend, body measurements and progress photos over time — so you see real change, read against where you're going, not just a single number on a bad morning.

ONE COACH FOR EVERYTHING The same coach runs the whole loop — check-in, train, fuel, ask, adjust. Ask it anything and it answers with your numbers in hand, makes a sensible call within set guardrails, and explains it in a line. Consistency is the whole game, and the system is built to keep you in it.

BUILT FOR CONSISTENCY Quick daily check-ins, four rings to close, and a coach that reads the 7-day trend so one heavy meal or one bad night never derails the plan. Small, steady, repeatable — that's how goals get hit.

SUPPORT ON A GLP-1 If you're losing weight with the help of a GLP-1 medication, Stackdd builds your training and nutrition around it — protein targets and resistance training to help you hold on to muscle while the weight comes down, and steady habits for when you reach your goal. (Stackdd does not provide or manage medication; always follow your doctor's guidance.)

WORKS WITH APPLE HEALTH Steps, sleep and move calories sync automatically, so your home screen and your coach see the full picture without manual entry.

SAFETY BUILT IN Every reply is checked against ten coaching principles before it reaches you — honest, specific, evidence-led, no false promises. And if a conversation points toward disordered eating or crisis, it steps back and signposts the right help.

British-built. Trains in kg. There for every rep, every meal, every check-in — and it remembers all of it.
