Samsyn: Workout & Run Coach

Strength and cardio in one simple app. Science-backed routines, effortless logging, and progress you can actually see — week after week.

Your next set is already decided.

Samsyn is the no-nonsense training app built around one idea: show you exactly what to do next, then get out of the way. Pick a routine, show up, and Samsyn tells you which exercises to do today, your target sets and reps, and the weight you hit last time. No spreadsheets. No decision fatigue. No account required.

KNOW WHAT TO DO TODAY Your workouts cycle automatically from your start date. Open the app and your session is already laid out — exercises, target rep ranges, and last time's numbers, all on one screen. If you miss recording a workout or want to skip ahead you can just flip to another day in the routine.

LOG WITHOUT A KEYBOARD Spin the oversized weight and rep dials with your thumb — one hand, no typing, no typos. Your target reps and last weight are right there; tap Record and get back to lifting.

EVERY PR, CAUGHT INSTANTLY Samsyn scores every set against your history using estimated 1RM (Epley formula), so adding a rep or a pound both count. The moment you break a record, you'll know.

SEE YOURSELF GET STRONGER Watch your estimated one-rep max plotted over weeks, months, and years. Honest data, not dopamine — your strength curve does the talking.

ONE LOG FOR EVERY KIND OF TRAINING Strength, cardio, bodyweight, and mobility all live in one place — each with its own PRs, calories, and trends. Record outdoor cardio with GPS route, pace, distance, elevation, and live heart-rate zones, and import runs, rides, and swims straight from Apple Health.

A FULL-BODY EFFORT MAP A visual muscle heatmap shows exactly what you've trained each session — and what you've been neglecting.
