Get Kynatx
Free forever for trainees. No account required to start — sign in later if you want cloud backup or a coach.
Android
The full app: offline tracking, rest timers, workout reminders and everything else. This is the one to get if you train with a phone in your pocket.
Any browser
The web version runs on desktop and iPhone with no install. It needs an account and an internet connection, since your data lives on the server rather than the device.
iPhone
There is no App Store build yet. On an iPhone, open the web version above and add it to your home screen — it behaves like an app, but it needs a connection.
What “works offline” actually means here
On Android, your training is stored on your own device and that copy is the real one. You can log every set of every session forever without ever signing in, and it will never ask you to. Signing in adds a cloud copy on top — and signing out again does not remove anything from your phone.
