Boostcamp
Why it's on this list
Boostcamp's powerlifting library is the broadest in the category. The free tier includes every major methodology: the official Jim Wendler 5/3/1 catalog (Boring But Big, Building the Monolith, 5/3/1 for Beginners), the canonical nSuns 5/3/1 with 4-day, 5-day, and 6-day variants, Cody Lefever's GZCL family (GZCLP, Rippler, Jacked and Tan 2.0, P-Zero Ultra), community-uploaded Sheiko routines, TSA 9 Week Intermediate and Beginner Approach (The Strength Athlete), Candito 6 Week Strength, 70s Powerlifter, and Bullmastiff. Every program runs with auto-progression baked in.
The tracker is tuned for the way powerlifters actually train. The plate calculator lays out each warm-up and attempt per side of the bar, which matters when you are working up to a heavy single, RPE and RIR sit on every set for autoregulated programs (RTS-style work, the RPE schemes in TSA templates), personal records are tracked on the squat, bench, and deadlift specifically, and the weekly reports show intensity and volume as you move through an accumulation or peaking block. All of that is free.
The dedicated apps below are excellent within their own methodology, but each commits you to one. Boostcamp puts Wendler, nSuns, GZCL, Sheiko, TSA, and Candito in one place, so switching methodologies between meets or running a hypertrophy off-season keeps a single training history and PR record. Pro adds the Strength Score, a per-muscle volume heatmap, and 20+ exclusive coach programs for $59.99/year ($4.99/month annual).
