Most training apps want to be a social network, a coach and a content library at once — and want an account before they will let you write down a set. Klemy is a tracker and nothing else. It opens instantly, it stays out of the way between sets, and it is built entirely with Apple's own frameworks, so it is easy on the battery on both the phone and the watch.

• Log a set in seconds, then put the phone down
• Nothing to read, nothing to scroll, nothing to buy but the app
• Native on iPhone, iPad and Apple Watch — no web views, no cross-platform runtime
• Free with up to three routines and unlimited workouts; unlimited routines by subscription or a single lifetime purchase, each with a Family version for up to six people

Years of logged sets are worth something, and most apps make them very hard to get back out. Klemy treats your history as your property, not as a reason you cannot leave.

• Arrive with everything. Import your history from other training apps, or from any CSV, with a column mapper for the awkward ones and a preview before anything is saved.
• Leave with everything. Export the lot as CSV or JSON, any time — no upgrade required and no support ticket.
• Keep your own backups, and restore one onto a new device.
• Import as often as you like. Nothing here is a one-shot you have to get right first time.
• Routines and history sync privately through your own iCloud; iPhone and Apple Watch keep each other in step directly.
