Best workout apps, by methodology and goal

5/3/1 is Jim Wendler's percentage-based strength template, built around four core lifts and a four-week wave. Most workout apps treat 5/3/1 as a custom routine you build from scratch. These four apps either include 5/3/1 as a pre-built program or are dedicated to the methodology, so you can start a cycle without doing the math yourself.

nSuns 5/3/1 is a high-volume linear progression program created by Reddit lifter 'nSuns' (Cody), built around 9 working sets on the top main lift and weekly AMRAP-driven progression. It's described in the community as 'Wendler in the front, Sheiko in the back'. Most workout apps treat nSuns as a custom routine you build from scratch. These three apps either ship the official nSuns template or are dedicated to nSuns specifically.

GZCL is Cody Lefever's tier-based strength framework, built around T1 (heavy compound), T2 (supplemental compound), and T3 (accessory) work with a 1:2:3 weekly volume rule. GZCLP is the linear progression variant for beginners. These three apps either ship the official GZCL programs as pre-built content or are dedicated to the GZCL family.

Boris Sheiko is a Russian powerlifting coach widely regarded as one of the most successful in the history of the sport: head coach of the Russian national team and coach of multiple world champions and record holders. His methodology centers on high-frequency percentage-based programming with numbered training cycles. Few apps ship Sheiko as named pre-built content, which makes this field narrow but well-defined.

Reddit PPL is the Push/Pull/Legs program created by Reddit user /u/Metallicadpa, posted to r/Fitness in 2015 and added to the r/Fitness wiki as the recommended PPL routine. It is a 6-day full-body powerbuilding split combining linear progression on heavy compound lifts with higher-rep accessory work. Few apps ship Metallicadpa specifically as pre-built content with auto-progression. These three apps either ship the canonical Reddit PPL natively or are strong general trackers for running it as a structured routine.

Hypertrophy training is volume-driven, periodized, and slow over months and years. The best apps for hypertrophy either ship structured hypertrophy programs from credentialed coaches or generate science-based programming based on your recovery and progression data. These four apps are the strongest options in the category.

Competitive powerlifting training is built around percentage-based loading of the squat, bench, and deadlift, with structured peaking blocks before meets. These four apps either ship the canonical powerlifting methodologies as pre-built content or deliver personalized powerlifting programming from elite coaches.

Natural bodybuilding training is hypertrophy-focused, slow over years, and built on long-term progressive overload rather than peak performance windows. The best apps for natural training either ship programs from credentialed natural pros or deliver science-based hypertrophy programming with rigorous volume management.

Most workout apps describe themselves as 'free with in-app purchases', then paywall the features that matter (programs, RPE, supersets, analytics). These four apps have genuinely generous free tiers where the core functionality is included with no time limit. They are compared here on what the free tier actually covers.

RPE (Rate of Perceived Exertion) and RIR (Reps in Reserve) are the two intensity-tracking fields most modern strength and hypertrophy programs depend on. Most workout apps gate them behind paid tiers. These three apps either ship RPE/RIR as a first-class set-level field on the free tier or surface them as a core feature.
