Progressive Overload App: Which Ones Actually Progress You

Our bias, stated first

We make one of the four apps in this article. Pocket Fit is ours, so treat every sentence about it as a claim from an interested party and check it against the app itself. Everything we say about Strong, Hevy and Fitbod comes from those companies' own pricing pages, help centres and App Store listings, all checked in July 2026, and the sources are listed at the end. Where a competitor does something better than us, we have said so. There are two places below where we recommend a different app than ours.

This article is about one narrow question, which is how each app handles progression. If what you actually want is a general verdict on which workout tracker to buy, including Boostcamp and Jefit and a much longer feature comparison, read best workout tracking app instead and come back here if the progression logic is your deciding factor.

One more thing worth saying at the top: three of these four apps genuinely automate progression. This is not an article where we are the only one that does the clever thing. The differences are in what each one progresses, when it decides you have earned more, and how much of that decision you are allowed to see.

What progressive overload actually is

Progressive overload means the demand you place on a muscle has to keep rising, or the muscle has no reason to change. That is the whole idea. It is not a programme, a split or a brand of training. It is the reason any of those things work.

The demand can rise in several ways. More weight on the bar is the obvious one. More reps at the same weight is the same thing wearing different clothes. More sets, shorter rests, better range of motion and slower lowering all count too. In practice, for anyone not competing, the two that matter are reps and weight, in that order.

That ordering is the part most people get wrong, and it is the part an app can either help with or actively ruin. We wrote a longer piece on the mechanics in progressive overload: reps first, then weight, and it explains the rule in more detail than this article will. This one is about which app runs the rule for you.

The question that separates these four apps

Ignore feature lists for a moment. There is one question that puts these apps into groups:

When you finish a set, who decides what number goes on the bar next time?

There are only three possible answers, and every workout app on the market gives one of them.

You do. The app records what happened and shows it to you next time. It is a notebook with charts. Strong is the best example of this, and it is very good at it.

The app does, from a rule you can read. It has a stated condition, you either meet it or you do not, and the weight moves accordingly. Hevy's Trainer works this way, and so does Pocket Fit.

The app does, from a model you cannot inspect. You get today's numbers, they are usually sensible, and the reasoning is not shown. Fitbod is the clearest example.

None of those three is wrong. They suit different people, and the wrong one for you will get abandoned in five weeks regardless of how good the algorithm is.

Strong: the best logger here, and it will never progress you

Strong is a workout log, and after years of use it is still the one lifters recommend to other lifters. Accounts are free forever. The free tier gives you unlimited workouts and caps you at three custom routines. Strong PRO removes that cap and unlocks the rest: supersets, custom exercises, CSV export, Apple Health, a warm-up calculator, RPE, advanced charts, body part measurements, workout scheduling and a muscle heat map.

Pricing on the App Store is one month at $4.99, six months at $19.99, a year at $23.99 or $29.99 depending on your region, and a one-off PRO Forever at $79.99 or $99.99.

What Strong does not do is tell you what to lift. Its closest feature is the Focus Metric, which lets you pick a metric per exercise so the app can, in Strong's own words, compare it "to the last time you performed that exercise." That comparison is genuinely useful, and it is still a comparison, not an instruction. The decision stays with you.

If you already know how you want to progress, that is a feature and not a gap. A CSV export and a clean chart are worth more to you than a suggestion you would override anyway. If that describes you, buy Strong PRO and stop reading comparison articles. It costs a third of what our app does and it will not argue with your programme.

If you do not already know how you want to progress, Strong will faithfully record five months of the same three weights, and it will not once mention that this is a problem.

Hevy: the cheapest automatic progression on this list

Hevy started as a logger with a social feed and has since added Trainer, which Hevy describes as "an adaptive strength programming system based on a sophisticated algorithm" that "creates personalized programs with built-in progressive overload, tracks your performance, automatically adjusts your working weights, and offers helpful tips."

The condition for a weight increase is published, which we like: you have to hit the upper end of the rep range with a given weight on all the prescribed sets before Trainer moves it. That is reps first, then weight. It is the same shape of rule we use, arrived at independently, and its logic is sound.

Trainer is Pro only. Pro is $2.99 a month, $23.99 a year, or $74.99 for lifetime, and Hevy's own site quotes those figures. Per year that makes it the cheapest automatic progression in this comparison by a wide margin, and the lifetime option is unusual enough to be worth noticing.

The free tier is real but bounded. Hevy's help centre states the free version allows up to 4 routines and up to 7 custom exercises, and shows stats history for the past 30 days or 3 months, against unlimited routines, unlimited custom exercises and 1 year plus all time history on Pro. Every workout and routine, free or Pro, has a 150 set cap.

Hevy's limit is that it is a lifting app and only a lifting app. It knows your sets. It does not know that you slept five hours, that you have been eating 400 calories under maintenance for three weeks, or that the reason your bench stalled is neither your bench nor your programme. If you want progression logic and nothing else, that boundary is clean and the price is honestly very hard to beat.

Hevy and Fitbod are the two apps people most often end up choosing between, so if that is your shortlist, Hevy vs Fitbod puts them head to head on price, free tiers and platforms as well as progression.

Fitbod: it decides everything, and you cannot see why

Fitbod is the most automated app of the four. It builds each session for you rather than asking you to build a routine first. Fitbod says it "dynamically tailors workouts based on your fitness level, performance history, recovery status, available equipment, and training goals," that it uses "non-linear periodization to optimize your workouts for sustained progress," and that its adaptive AI "learns from your edits to its workout recommendations." Its own FAQ says the algorithm applies progressive overload to maximise gains.

In practice that means you open the app and today's workout exists, with weights and reps already filled in, chosen partly on which muscles it thinks are still recovering. For a large group of people this is exactly right. If choosing is the thing that stops you training, an app that never makes you choose is worth paying for.

Two honest criticisms. First, the reasoning is not exposed. When the weight goes up you are not told which condition you satisfied, so you cannot learn the rule and you cannot tell a good call from a coincidence. Second, it is the most expensive app here. App Store in-app purchases run at $12.99 or $15.99 monthly and $79.99 or $95.99 for a year of Fitbod Elite, with cheaper legacy tiers grandfathered for older subscribers, and Fitbod's FAQ quotes $15.99 monthly and $95.99 annual when bought through their website. There is no permanently free tier, only a trial.

That last point matters more than it looks. Around $96 a year buys you excellent training automation and no food tracking, which means the second subscription is still ahead of you.

Pocket Fit: reps first, then weight, off a confirmed plateau

Ours works on a stated rule, and here it is in full so you can judge it rather than trust it.

You are given a rep range for each exercise. While you are still inside that range, the weight does not move, and the target is one more rep than last time. When you hit the top of the range on every prescribed set, the weight goes up by the smallest increment your equipment allows and the reps reset to the bottom of the range. If you miss the target twice in a row at the same weight, that is a confirmed plateau, and only then does the plan change around you.

Two deliberate choices inside that. The steps are small on purpose, because the smallest jump you can make is the one you can make most often. And the bar only moves off a confirmed plateau, twice, not once, because a single bad set is far more often a bad night than a real ceiling.

The part that is genuinely ours rather than a better version of what Hevy does: Pocket Fit holds your food and your sleep in the same app as your sets. So when the rule says you should have earned a heavier squat and you did not, the app has the other two variables in hand. A week of short nights or three weeks in a deficit is a reason to hold the weight and lighten the session, not a reason to conclude you have plateaued. An app that only sees your sets has to interpret that data as a training failure, because a training failure is the only kind of failure it can see.

Pocket Fit is $9.99 a month or $59.99 a year, which is £59.99 or €59.99 in those currencies, against $119.88 if you paid monthly for twelve months. Food tracking is included in that price while we launch, rather than sold as a second subscription.

The four side by side

Prices are the figures published by each company in July 2026 and vary by region and storefront. Check the price your own store shows you before you buy anything.

What none of these apps can do

An app cannot make the demand rise. It can only notice whether it did.

No app on this list, including ours, can put weight on a bar you did not load, produce an adaptation from a session you skipped, or invent recovery you did not take. Progression is not a software feature. It is a physiological response to a stimulus you have to actually apply, and every app here is a bookkeeper for that process rather than the process itself.

Two more limits worth stating plainly. None of the four can measure your effort directly; they all infer it from what you type, and if you log optimistically then every downstream calculation is optimistic too. And none of them, ours included, can tell the difference between a rep that ended in good form and a rep that ended with your lower back doing the work.

Where our own evidence runs thin: we can defend reps before weight, small increments and waiting for a second miss on the strength of how adaptation and fatigue behave, and there is no head to head trial comparing our specific increment rules against Fitbod's periodisation or Hevy's rep range condition. Nobody has run that study. Anybody claiming their app's progression algorithm is proven superior to a competitor's is telling you something they cannot know.

How to choose in two minutes

You already know how to programme. Strong. Cheapest way to a clean log and good charts, and it will never overrule you.

You want the weights decided, and price is the deciding factor. Hevy Pro. Published progression rule, roughly $24 a year, and a lifetime option if you hate subscriptions.

You do not want to think about training at all. Fitbod. Most automation of the four, and you pay for it twice over, in money and in not seeing the reasoning.

Your training keeps getting derailed by food and sleep rather than by programming. Pocket Fit. One rule you can read, and the only one of the four that holds the other two variables in the same place.

Put it together

Progressive overload is not the feature you are shopping for. What you are actually shopping for is a rule that survives contact with a bad week, and an app honest enough to tell you which one it is using.

Strong hands the rule back to you. Hevy publishes one and charges very little for it. Fitbod runs one it will not show you. We run one we have printed above, in a place where your sleep and your food are also on file, so a stalled lift can be diagnosed rather than merely recorded.

Pick the group you belong to first, then the app, then start adding reps.

Progressive overload apps: common questions

What is the best app for progressive overload?

There is no single best one, because the apps differ on who makes the decision rather than on quality. If you want to make it yourself, Strong. If you want it made from a published rule at the lowest price, Hevy Pro. If you want it made for you with no input, Fitbod. If you want it made from a published rule alongside your food and sleep, Pocket Fit.

Does Strong app have progressive overload?

Not as an automatic feature. Strong logs your sets and its Focus Metric compares an exercise to the last time you performed it, which supports your own progression decisions without making them for you.

Is Hevy Pro worth it for progression?

If automatic progression is the feature you want, Hevy Pro is the cheapest route to it on this list at $2.99 a month or $23.99 a year, and its increase condition is published. The trade is that Hevy only sees your lifting, so it cannot account for sleep or food when a lift stalls.

Can an app tell me exactly when to add weight?

It can tell you when you have met a stated condition, which is a genuinely useful thing and not the same as certainty. The apps that publish their condition, like Hevy and Pocket Fit, let you check the reasoning. The apps that do not, like Fitbod, require you to trust the output.

Do I need an app for progressive overload at all?

No. A notebook works, and it worked for decades. What an app adds is that it remembers the number you hit five weeks ago on an exercise you have done twelve times since, which is precisely the thing human memory is worst at and where most self directed progression quietly stops.
