LiftProof vs. Strong

Strong has earned its reputation. It is fast, stable, and gets out of the way — you open it, log your sets, and close it. Powerlifters and experienced gym-goers who follow their own programming or work with a coach reach for Strong because the interface is clean and the friction is low. It does not try to tell you what to lift. It just records what you did.

That simplicity is also its limitation for a certain type of lifter: one who does not have a coach, does not want to research programming, and just wants to get stronger. Strong is a logbook. It writes down what you did. The programming knowledge has to come from somewhere else — a coach, a spreadsheet, a book, your own experience. For lifters who lack that external structure, the log alone does not move them forward.

LiftProof takes the opposite approach. The programs — 5/3/1, linear progression, PPL — are built into the app. When you open a session, LiftProof already knows what you are supposed to lift based on your training max and where you are in the program cycle. Progressive overload is tracked automatically. You do not bring the programming; the app holds it.

Who each app is for comes down to where the programming lives. If you have a coach setting your program, a well-tested spreadsheet, or enough experience to self-program with confidence, Strong is a clean and reliable place to record the work. If you want the app itself to handle the structure — to know what comes next, to manage load progression, and to keep you on a defined path — LiftProof is built for that role.

LiftProof if you want the app to drive your programming. Strong if you have your own coach or program and need a fast, reliable logger.
