Built Log

Get Built, and log

Log a set in a few taps. Every personal record is caught for you.

A workout and running log that works offline and needs no account. Your training data lives in a database on your phone.

What makes it different

It works with no account

Open it and start logging. Workouts, runs, bodyweight, sleep and macros stay on your phone, and nothing is collected if you never sign in.

Records find themselves

Beat a lift and it is flagged the moment you log the set. Nothing to enter by hand, nothing to go back and tidy up.

The coach runs on the phone

It reads your own logged sessions and names one thing to change this week, computed on the device with no network call. Every finding opens to show the numbers behind it.

What it looks like
