Gym or home — your plan is ready either way. PlusOne is a clean, quiet training app. Tell it your goal, where you train, and what equipment you have. It lays out what to do each day, how much to lift, how long to rest. The training screen works like a player: finish a set, tap once, done. No ads. No feed. Not many features — but the ones you'll actually use. TRAINS LIKE A PLAYER Your exercises are queued up like a playlist. Finish a set, tap once, and it moves to the next one and starts the rest timer on its own. Nothing to think about while you train. REAL DEMOS, NOT STICK FIGURES Every exercise has a photo of a real person, with the working muscles highlighted on the body. GYM AND HOME, SAVED SEPARATELY A full gym, one pair of dumbbells at home, a hotel room with nothing — save a setup for each. Your plan only includes what you can actually do. Machine taken? Swap it in one tap. TRAIN WHEN YOU FEEL LIKE IT The plan is ready, but it doesn't own you. Want a different muscle group today? Short on time? Feeling good and want to add one more? All fine. SEE WHAT YOU'VE DONE A six-axis strength profile shows which areas are falling behind. A calendar marks every session you've logged. TRAIN FROM YOUR WRIST See your exercises, log your sets, and check your heart rate on Apple Watch. No phone needed. BUILT FOR WOMEN TOO Strength progression and recovery aren't one-size-fits-all. The algorithm adjusts exercise selection, load progression, and rest for women's physiology — not by making it easier, but by making it right. WORKS AROUND YOUR INJURIES Bad knee, tweaked back, cranky shoulder — tell it, and it won't program those movements. It finds you a substitute instead. Not removed, replaced. JIAJIA AND YIYI Two AI coaches stay with you the whole way. After each session they sum up how it went, and they build your next training cycle too. PlusOne. Always one more.
