Offline

An offline workout tracker. The set never waits for the server.

Basement gyms and steel buildings lose the signal. Dren writes each set on the phone the moment you check it, and syncs the workout when the phone is back online.

What works with no signal

The whole workout.

• Start an empty workout or a routine.
• Check every set. Each one is saved on the phone.
• Last time, on the exercise, from the log already on the phone.
• The rest timer counts down on screen.
• Finish saves the workout on the phone.

When the signal comes back

Finish syncs if the network is there. Otherwise the Sync button sends it when you are back online. History also syncs when you open it. A new phone, after login, gets the training back.

What needs the network

The push that says rest is over needs a network and a notification token. The on-screen timer does not. ChatGPT sees a workout after the phone syncs.
