"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"

Common questions
Logbook is an iPhone app for logging strength training. It is built for lifters who follow a structured program and want their workouts on a notebook-style log. No social feeds, no AI coach, no monthly subscription. One purchase, lifetime access.
Three paths, all in the same import sheet. Paste anything (a coach's email, a screenshot of a PDF, a spreadsheet) and Logbook structures it for you. Dictate the block in your own words. Or write it in Logbook Notation — a small, readable syntax for sets, reps, RPE, percent of 1RM, and per-week prescriptions.
$49.99 once. No subscription. Seven-day free trial. Every feature is included on day one and stays included. We will not paywall existing features later.
Yes. The app is offline-first. Log sets, edit loads, finish a session with no signal. iCloud sync runs in the background when you are back online so your history stays on every device you own.
PRs are detected automatically as you log sets — no confetti, no badges. The Progress view tracks top-set evolution, estimated 1RM, and volume per exercise over time. Tap any data point to jump back to the session that produced it.
Both. Write @8 for RPE 8, @75% for 75% of 1RM, or a literal weight like 100kg. Mix them freely across exercises. RPE and percent are intent — the lifter chooses the bar at session time.
Yes. CSV export of your full session history, anytime, from Settings. Your data is yours. We do not lock it in.
Both, plus general strength work. The structure (workouts, exercises, sets) is universal. If you follow 5/3/1, nSuns, a hypertrophy block, a peaking program, or a custom plan from a coach, it fits.
No. No feeds, no followers, no sharing prompts. The app is a private training notebook.
iPhone, on iOS 17 or later. iPad runs the iPhone build. No Android or web client today.
One payment. No subscriptions. No features pulled behind a paywall later.
