PersonalBestie uses your own logged training as context for progression, adjustments, and next-step advice.

Shareable routines

Instant AI Recaps

Data-driven breakdown the moment you finish

Automatically analyze your session, highlight PRs, and get grounded suggestions for your next session.

How it works

Plan it, log it, review it.

PersonalBestie is built like a proper fitness tracker first. That structure is what makes the AI features useful instead of gimmicky.

01

Create a routine

Set up push, pull, legs, upper/lower, or any split you actually use, then share that routine instantly when you want someone else to follow it.

02

Track each set

Keep reps, load, and session detail attached to each workout so your progress is easy to review and your AI coach has real context.

03

Instant AI Feedback

Finish your workout and get an immediate, evidence-linked recap. See exactly what changed, what stood out, and get a data-driven suggestion for your next session to keep the momentum going.
