Best iOS Weight Lifting App for iPhone & Apple Watch (2026)
By Musklr Team · Published 1 July 2026 · Updated 1 July 2026
Most lifters want the same few things from a tracking app: log a set without slowing down, never lose a session, and see whether the numbers are going up. We compared the five most popular iOS lifting apps side by side: Musklr, Strong, Hevy, Jefit and Fitbod. The comparison covers the seven things that actually decide which one you keep: price, exercise library, Apple Watch support, offline logging, ads, muscle heatmaps and built-in programs.
For the job most people are really asking about, which is registering sets quickly on an iPhone or Apple Watch, Musklr came out on top. It has the largest exercise library, a live muscle heatmap, two-tap logging and a full Apple Watch app, and full features run about $2 a month. We've flagged where each competitor beats it too, because several do.
The best iPhone workout tracker apps, compared
Musklr, Strong, Hevy, Jefit and Fitbod compared on price, built-in exercises, Apple Watch, offline logging, ads, muscle heatmap and programs. Apps run across the columns; features down the rows.

Green best, amber middle, red weakest in each row; grey = not documented.
Prices and features verified 1 July 2026; subscriptions vary by region. Musklr Pro is $2/mo billed annually; Hevy's Pro price is approximate. "Not published" means the vendor doesn't list an exercise count. "Not stated" means offline use isn't documented on the vendor's own pages (it may still work). Hevy shows muscle-group volume charts rather than a body heatmap.
A closer look at each app
Musklr: fastest logging, best value
Musklr is built for one job: registering sets as fast as possible, on iPhone and Apple Watch. It has the largest exercise library here, a live muscle heatmap, live heart rate on the watch, and it logs offline with no account. It's free to use for as long as you like, and Pro is about $2 a month for unlimited routines and cloud sync. If you want the quickest, most complete way to log your own training, it's our pick.

Strong: simplest, fastest logging
Strong earns its name by getting out of the way. It's a clean, minimal logger with a capable Apple Watch app, so you can run a whole session from your wrist. The free tier caps you at three routines, and the moment you want more, Pro is $4.99/mo (with a one-time lifetime option), more than double Musklr's roughly $2 a month for full features. If you want the least-cluttered way to record sets and don't need analytics or a big exercise library, Strong is hard to beat.
Hevy: best free tier
Like the others, Hevy is freemium, but its free tier is the most generous here: no ads, unlimited workouts, up to four saved routines, and a big, active community of 14M+ athletes with a polished routine planner. If getting the most without paying is your priority, start with Hevy. It leans on muscle-volume charts rather than a live heatmap, and it doesn't publish an exercise count, so there's nothing to weigh against Musklr's published 2,000+ movements. But as a free tier, it's the one to beat.
Jefit: deepest analytics and instructions
Jefit is the one for data lovers: 1,400+ exercises with guided instructions, expert-built plans, a muscle-recovery breakdown, and some of the deepest progress analytics in the category, backed by a huge, long-established user base. The trade-off is ads on the free tier, which Elite ($12.99/mo) removes. If you want structure and detailed reporting more than speed, Jefit delivers.
Fitbod: best automated programming
Fitbod is the most hands-off app here. Its algorithm builds and adapts each session around your recovery, so it tells you what to train next. There's no permanent free tier (a short trial, then from $12.99/mo), and it's built around guidance rather than fast manual logging. If you want a coach that programs for you, Fitbod leads. That's a genuinely different job from the one Musklr does.
Why Musklr wins for logging
Musklr is built around one job, registering sets as fast as possible, and it brings the tools of a heavier app to that job without slowing down. That combination is why it's our overall pick.
