No signal? Keep logging
Basement gyms and dead zones don't stop a session. 3Lite keeps working with no signal: the main sections and pages you've visited open from your phone, and your sets save and sync when you're back online.
Replaces a paper log for when there's no signal. Part of one app, for one subscription.

How it works
Works offline, step by step
- 01
Add 3Lite to your home screen
On iPhone, Safari → Share → Add to Home Screen. On Android, Chrome → Install app. It opens full screen.
- 02
Log as normal
With no signal, each set is saved on your phone straight away.
- 03
It syncs itself
When the connection returns, the app regains focus, or every 20 seconds, sets sync in order.
- 04
Finish safely
Finish waits until your sets have synced, so nothing is lost.
