The best workout log app for tracking sets and reps

The short answer

Ranked by how much of a normal session you can record without thinking about the app, then adjusted for what it costs and how long it has been around.

• Hevy: the one to install if you have no strong opinion. Fast tap logging, a free tier that covers four routines, and $23.99 a year if you outgrow it. 4.92 stars from over 85,000 ratings.
• Strong: the cleanest logging screen on the App Store and the best Apple Watch app in the category, so you can record sets from your wrist. Free tier stops at three routines.
• Superset: you say the session out loud and it writes the sets, reps and weights for you. The fastest way to record a workout, and also the most expensive here at $49.99 a year with no free tier.
• HeavySet: the most control per set. Rep ranges, set ranges, AMRAP, RPE, rest presets per exercise. Free for unlimited improvised sessions, though its last update was August 2025.
• Alpha Progression: logs fine, but you are really buying its progression planning. 4.92 stars from a smaller base.
• JEFIT: the largest exercise database with video, plus a web interface for editing your log on a laptop. The free tier carries ads.
• Fitbod: writes the session for you rather than recording one you brought. Excellent at that job, an awkward fit if you already have a programme.

Three different jobs people call "tracking sets and reps"

These get conflated constantly, and picking the wrong app usually comes from wanting one of them and buying an app built for another.

Recording what happened. You did 135 for eight, then eight, then six. You want that stored accurately, quickly, with per-set reps that differ from each other, and you want to see it next week when you are standing at the same bar. Every app on this list does this. They differ enormously in how much handling it takes.

Prescribing what should happen. Rep ranges, set ranges, percentages of a training max, RPE targets, AMRAP finishers. This is the plan, and it lives in the app before the session rather than after it. HeavySet and Alpha Progression are built for this; Hevy and Strong hold a simpler version of it in their routines.

Reading the log afterwards. Volume per muscle group, estimated 1RM curves, whether last month went anywhere. Most apps have a charts screen. The ones with a web interface, JEFIT in particular, are far easier to actually study.

How the logs compare

#1 Hevy: the default answer for most lifters

Hevy's logger is the one other apps copy. Weight and reps sit under your thumb, the previous session's numbers are already there as grey placeholder text, and adding a set is one tap. Per-set reps that differ are handled without any friction, which sounds trivial until you use an app that averages them.

The free tier is the most generous of the well-known trackers: four routines, seven custom exercises, and your full history stays readable rather than being rationed. Paying removes the caps for $2.99 a month or $23.99 a year, which is a third of what most apps here charge. It also has a web app, a social feed, and Android, so it survives a phone switch.

Where it stops: there is no voice logging, no built-in coaching that tells you what weight to use next, and its exercise entries are thinner than JEFIT's if you want instructions for an unfamiliar machine.

#2 Strong: the cleanest screen, and a real Watch app

Strong has been the default iPhone recommendation for years for good reason. The logging screen is uncluttered, it never gets in your way, and it works offline without complaint. Its Apple Watch app is the best in the category, so you can record sets without taking the phone out of your bag.

The catch is the free tier: three routines, and that is the whole allowance. Beyond that it is $4.99 a month or $29.99 a year, or $99.99 once. For a lifter running a four-day split, the three-routine cap arrives on day four.

#3 Superset: say it instead of typing it

Superset attacks the problem from the other end. Instead of making the form faster, it removes the form. You finish training, hold the microphone button, and say something like "bench press, three sets of eight at 135, then incline dumbbell press, ten, ten and eight at fifty." The recording goes to a multimodal model that returns the exercises, sets, reps and weights already structured, and a review screen appears before anything is saved, so a misheard number is one tap to fix.

It handles the messy parts of a real session properly. Reps that differ per set, a bodyweight movement with no weight at all, a last set taken to failure. Because the model also sees the exercises you usually train, a mumbled name resolves against your own history rather than a generic dictionary. And 873 exercises with photographs and written instructions are stored on the phone, so the library works in a basement gym with no signal.

The honest limits, and they matter. Superset costs $49.99 a year, $7.99 a month or $3.99 a week after a 3-day free trial, and there is no free tier underneath: the paywall at the end of onboarding has no close button, so you cannot use the app without subscribing. It launched in August 2026 and has no App Store ratings yet, while every other app on this list has thousands. It is iPhone only, with no iPad, Android, web or Watch version. There is no structured superset or drop-set logging, only a free-text note. There is no CSV export and no rest timer. Apple Health sync is written but switched off in the shipping build. Voice logging also needs a connection, since the audio has to reach the model.

So it ranks third rather than first. On the single criterion of effort per session it is the fastest thing here, and if typing between sets is the reason your last three logs died, it is the one to try. On price and track record it is the riskiest pick on the page, and pretending otherwise would be silly.

#4 HeavySet: the most detail per set

If your programme specifies rep ranges, set ranges, AMRAP finishers, RPE targets or percentages of a training max, HeavySet holds all of it natively and most of this list does not. It also has native supersets and giant sets that auto-advance, rest timers with presets per exercise, a tempo metronome, a plate calculator, personal record notifications during the session, and CSV export at no charge.

Two things hold it back. Its last release was version 2025.1 on 20 August 2025, so it has sat still through two iOS cycles. And the free tier limits how many times you can run a routine you created, with imported or duplicated routines locked entirely, though improvised workouts stay unlimited.

#5 to #7: programming, databases and generated sessions

Alpha Progression is the most serious app here about planning progression: mesocycles, deload timing, per-lift schemes. Its logger is competent, but you are paying $79.99 a year for the planning rather than the recording.

JEFIT has the largest exercise database in the category, with video demonstrations and a web interface that makes reviewing a training block genuinely pleasant. The free version is ad-supported and limited, and Elite is $12.99 a month or $69.99 a year.

Fitbod is not really a log. It decides what you should train today and you tap through the session it wrote. If you already have a programme, most of what you pay $12.99 to $15.99 a month for goes unused.

How to keep a set-and-rep log you actually maintain

1. 1Pick the app whose recording method matches the moment. If you are willing to tap, Hevy or Strong. If you will not touch a phone mid-session, use one that takes voice.
2. 2Build your routine once, properly, with the real exercise names. Every shortcut you take here costs you a matching problem later when the app cannot line up two sessions of the same lift.
3. 3Record the top set first while you still remember it. Everything else can be reconstructed; the heaviest set cannot.
4. 4Write per-set reps honestly. Logging 8, 8, 8 when you did 8, 8, 6 makes next week's decision worse, and the decision is the entire point of keeping the log.
5. 5Note the one thing a number cannot carry: a grip change, a bad night's sleep, a bar that was loaded wrong. Two lines is enough.
6. 6Look at the last session before you start the next one. A log you never read is a diary, not a training tool.

How to pick

• You want one recommendation and no research: Hevy. Cheapest paid tier, biggest community, hardest to regret.
• You log from an Apple Watch: Strong, which is still the only one doing this really well.
• Typing between sets is why your last log died: Superset, if you accept the $49.99 a year and the lack of ratings.
• Your programme has ranges, RPE and training-max percentages in it: HeavySet, stale update date and all.
• You want the app to plan your progression: Alpha Progression.
• You want to study your log on a laptop: JEFIT, for the web interface.
• You do not have a programme and want one written for you: Fitbod.
• You are on Android: Hevy, JEFIT, Fitbod or Alpha Progression. Superset and HeavySet are iPhone only.
