Stackd vs GymTree

Training phases change. Work gets busy. Goals shift. Most fitness apps lock you into their programs. Stackd works with whatever plan you built this week — because your AI agent writes it, and Stackd just keeps score. IMPORT AI WORKOUTS IN SECONDS Design your program in any AI agent. Copy the JSON. Paste it into Stackd. Your full workout plan appears instantly — exercises, sets, rep targets, everything. No manual entry. No templates. No friction. TRACK EVERY SESSION Log sets, reps, and weight as you train. Stackd auto-fills your last session's weight so you always have a starting point. Hit your rep targets and the weight recommendation updates automatically — progressive overload built in. SEE YOUR STRENGTH GROW Estimated 1-rep max charts for every exercise. Watch your squat, bench, and deadlift climb week over week. Full session history so you never lose a workout. NUTRITION TRACKING INCLUDED Log meals and hit your macro targets without switching apps. Build daily meal plans, track protein, carbs, and fat. Everything in one place. BUILT FOR LIFTERS WHO PLAN WITH AI Most fitness apps want to sell you their programs. Stackd assumes you already know how to use AI Agents to build a better one. We just give those programs a home. No ads. No upsells inside the app. Cancel anytime.
