TRACK YOUR WEIGHT Log your body weight and monitor your changes over time, synced with Apple Health. YOUR DATA, YOUR DEVICE Your training data is personal — how hard you push, how you're progressing, your body weight over time. With Gain, that data belongs to you alone. Everything stays on your devices and syncs only through your own private iCloud account. No accounts, no analytics, no third parties — privacy isn't an afterthought, it's built into how Gain works.
