Checkfit vs Boostcamp.
Both apps let you follow a structured program and log clean, set-by-set. The difference is where the program comes from: Boostcamp hands you a preset someone else wrote, the same for every user; Checkfit calibrates one to your strength and rewrites it as you change.
What Boostcamp is
Boostcamp hosts a library of preset, community programs — 5/3/1, nSuns, PPL, GZCLP — with a logger to run them. If you already know which template you want, it will run it for you. But the same numbers ship to everyone: a preset can't know your current strength, can't pick your weight each set, and can't autoregulate from how the last session went. It's a fixed plan and a place to record it.
Why lifters choose Checkfit
Every program on Boostcamp is written for the average lifter, and nobody is the average lifter. You run the same fixed template as everyone else, with starting maxes you guess at and a progression scheme that never reacts to how your sessions actually go.
Checkfit writes a program from scratch. It calibrates a six-week hypertrophy mesocycle from two lifts you know, picks every weight, manages your volume, schedules deloads, and rewrites each session from the reps in reserve you logged last time. Boostcamp's programs are the same template for everyone; Checkfit's output is a session built for you, this week. That's hypertrophy science automated, not a PDF you run on faith.
An optional coach connection comes with it, too — a real person who can see the same sessions and adjust with you. Boostcamp gives you a plan to follow; Checkfit gives you a plan that follows you.
What a preset can't do
A template is a fixed set of instructions. It can't know that your bench moved and your squat didn't, that last Tuesday's top set left four reps in the tank, or that six weeks of accumulated volume means it's time to back off. Those are the decisions that separate progress from spinning, and on Boostcamp they're all yours to make — including the starting maxes the whole template hangs on.
Checkfit makes them for you. It calibrates the mesocycle from two lifts you already know, computes the load for every set from RIR-based math, keeps weekly volume inside the range that drives growth, and schedules the deload before you need it. That runs for $17/mo with the coach connection included — less than a template plus a coach, and it never ships you someone else's numbers.

The verdict
Both apps run a structured program and log it cleanly. Everywhere past that, Checkfit does more: Boostcamp ships the same preset numbers to every user, while Checkfit builds the program around your lifts, picks every weight, adjusts each session from your reps in reserve, and manages volume and deloads — programming and coaching in one $17/mo subscription. Free-but-generic leaves the rest to you. Get the whole job handled: get Checkfit.
