MASSIVThe Best App for 5/3/1 in 2026
A good 5/3/1 app has to do three things: hold your training max per lift, calculate each week's percentages through the 5/5/5, 3/3/3, 5/3/1 and deload wave, and raise the max at the end of a cycle. Most trackers do none of it and leave you with a spreadsheet. Massiv runs the wave for you and rounds every percentage to plates you can actually load.
The best 5/3/1 app depends on what you want automated. Choose Boostcamp if you want a large free library of published 5/3/1 variants, a general tracker such as Hevy or Strong if you prefer to build and control the routine yourself, or Massiv if you want a focused program runner with plate-rounded working weights and progression built in. The useful comparison is not whether an app can store three sets—it is whether it handles the specific 5/3/1 template, training max, AMRAP set, and next cycle the way you expect.
What actually makes an app good for 5/3/1
5/3/1 is simple to understand and tedious to administer — that gap is the whole reason a dedicated app matters. If you're new to the program, the full 5/3/1 guide walks through the mechanics; in short, a genuinely good 5/3/1 app should:
- Hold a training max per lift (90% of your 1RM) and calculate every working set from it.
- Show today's exact weights, rounded to plates you can actually load — not just raw percentages.
- Log the AMRAP/PR set rep count and treat it as your progress signal.
- Run the four-week wave automatically and bump the training max (+5 lb upper, +10 lb lower) after each deload.
- Support assistance templates (BBB, Triumvirate, FSL) without manual setup.
A general tracker can be perfectly adequate if you enjoy managing the program. A program-led app earns its place when it removes that setup and cycle administration without hiding the rules.
The honest comparison
No single app is best at everything. Here's where each one actually earns its place:
| App | Best at | The catch for 5/3/1 |
|---|---|---|
| Hevy | Logging, progress charts, routines, and social features | General-purpose tracker; verify the exact 5/3/1 template and cycle behavior you want |
| Boostcamp | Free published 5/3/1 variants with AMRAP targets and cycle auto-progression | Broad program platform rather than a single-method app |
| Strong | Fast template-based logging | You create or adapt the workout template; the free version allows three templates |
| Fitbod | Adaptive workouts based on goals, history, equipment, and recovery | Designed around its recommendation algorithm, not a fixed 5/3/1 cycle |
| Dedicated 5/3/1 calculators | Spitting out the percentage table | Calculator only — no logging, no AMRAP tracking, no progression memory |
| Massiv | Running the wave end to end: TM, plate-rounded weights, AMRAP, auto-progression | Program-focused, not a social network or open community library |
The honest summary: Hevy is strongest here when logging and community are the priority. Boostcamp is the clearest choice for a free library of published 5/3/1 variants and already includes cycle progression. Massiv is built for lifters who want a quieter, focused program runner that turns the selected template into today's plate-rounded session and carries its progression forward.
How to choose
Match the app to how much you want to think about the program:
- You like driving the program yourself and just want clean logging + a community → Hevy or Strong.
- You want free, ready-to-run 5/3/1 variants with AMRAP targets and cycle progression → Boostcamp.
- You don't want to run a program at all and prefer an algorithm to decide each day → Fitbod (see our Fitbod alternative piece if the subscription is the sticking point).
- You want 5/3/1 run for you — correct percentages, loadable weights, AMRAP-aware, auto-advancing — → a dedicated program engine like Massiv.
One more filter: check whether the app does plate-rounded weights and remembers your AMRAP history. Those two details are where generic trackers quietly fall down on 5/3/1, because they were built to log any workout, not to run a percentage-based wave.
Free vs paid: what you should actually pay for
You do not need to pay anything to run 5/3/1 — a notebook and a calculator work. So the only thing worth paying for is the part that removes friction every single session: the app showing you the loaded weight, reading your AMRAP, and advancing the cycle so you never recompute the table. If an app charges a subscription but still makes you manage the wave yourself, you are paying for storage, not for 5/3/1.
A reasonable way to think about it:
- Free is fine if you are happy doing the program setup yourself in a general tracker—or if a published free Boostcamp template matches the 5/3/1 variant you want.
- Paid is worth it only when it buys automation you would otherwise do by hand every workout — training-max tracking, plate rounding, AMRAP-aware progression.
- Watch for algorithm lock-in. Apps that generate their own daily workouts (Fitbod) are paying you back in convenience, but they are not running Wendler's 5/3/1 — they are running their model. If you specifically want 5/3/1, that is a mismatch.
Don't forget the watch and your history
Two practical details decide whether you'll actually stick with an app for 5/3/1. First, watch logging: 5/3/1's long rest periods between heavy sets are far less annoying when the rest timer and next set live on your wrist — see the best Apple Watch lifting apps for what good wrist logging looks like. Second, migration: if switching apps means re-entering months of training maxes and PRs by hand, most people won't bother. Pick something that imports your existing history.
Quick FAQ
Is there a truly free 5/3/1 app? Yes. Boostcamp currently lists multiple free 5/3/1 variants with week-by-week structure, AMRAP targets, and cycle auto-progression. General trackers can also store a routine on a free tier, but their setup and automation differ.
What about a 5/3/1 calculator? Calculators give you the percentage table once, but they don't log your sets, track AMRAP reps over time, or advance the cycle. They're a starting point, not a training app.
Does Massiv cost money? Massiv has a genuinely useful free tier with every built-in program, unlimited workout history, watch logging, imports and exports, and a 30-day automatic-progression preview. Pro adds always-on progression, the full program builder, body tracking, monthly recaps, and deeper analytics.
How Massiv handles this for you
Massiv ships 5/3/1 as a built-in program and runs the entire cycle: it holds each lift's training max, shows today's working sets rounded to the plates you own, records your AMRAP reps as the progress signal, and advances the wave — including the deload and the post-block training-max bump — without you doing arithmetic. It also imports your history from Strong, Hevy, Fitbod, StrongLifts, FitNotes, and Jefit, so switching doesn't cost you your numbers.
Massiv runs the progression math for this program automatically. Download Massiv and put it to work in the gym.
