About this app

Train only S-TIER.

Most workout apps just log your sets. S-TIER ranks every exercise from D to S by real effectiveness for your goal and your equipment — so you stop wasting sets on lifts that don't deliver.

WHY S-TIER
• Tier-ranked exercises — every movement rated D to S, so you always train what works
• Your AI coach — a personalized plan built around your highest-rated lifts, adapting to your goals, gear and progress
• STIER Score — one number (0–1000) for your bodyweight-relative total strength, climbing as you get stronger
• Track every set — log reps, weights and RPE; watch your rings close week after week
• AI Body Preview — see where your training can take you, generated from a single photo

BUILT FOR THE GYM
• Works with your equipment — barbell, dumbbells, machines or just bodyweight
• Offline-first logging — record every set even with no signal
• Smart progression — the right weight and reps, suggested set by set
• Light & dark themes with your own accent color
• Fully translated: English, German, Spanish and French

Set your goal, get your ranked plan, and train only what earns its place.
