Sound familiar?

"If it takes more than 30 seconds to log a set, the app is too slow."

Logbook: one tap to check off a set. Your rest time stays rest time.

"I don't understand the usefulness of the community section, it feels like the developer is trying to push that."

No social layer. No feeds, no followers, no sharing prompts.

"The app requires an internet connection to log workouts; why not just save them offline?"

Offline-first. No signal in the gym? No problem.

"For lifters who follow structured programs, AI recommendations are noise at best, actively wrong at worst."

No AI coach. Your program, your way.

"just want to log my numbers"

"feels like using a notebook"

"electronic pen and paper"

"opens and I'm in, no setup"

What lifters keep asking for. What we built.

Log sets in seconds.

One tap to check off a set. Edit load on the fly. Auto-fill from your last session. Between sets is rest time, not navigation time.

Bring any program.

Paste a spreadsheet, type it in your own words, or use our training syntax for precision. However you describe it, the AI reads it and builds your full plan. No forms. No configuration screens. Just describe and go.

Track every PR.

Top set evolution, estimated 1RM, volume analysis. Automatic PR detection — discreet, no confetti. Just your numbers over time.

Every session, remembered.

Add notes to any exercise or to the session itself — they stay with the entry and resurface when you need them. Your full training history, searchable and exportable. CSV export anytime. iCloud sync. Your data, your rules.

Logbook session view — one tap to log a set

Finally, an app that gets out of the way.
