Best 5/3/1 Trackers (2026): Apps That Actually Run Wendler Properly

Jim Wendler published 5/3/1 in 2009 and it has outlasted virtually every lifting program since. The reasons are simple: the math is forgiving, the Training Max keeps progression sustainable across years rather than months, and the supplemental work (Boring But Big, First Set Last, Joker sets) lets the same skeleton fit a wide range of goals. The catch is that running 5/3/1 properly means tracking five things at once — the main lift wave, the supplemental scheme, the assistance work, the deload week, and the Training Max math after each cycle.

Most lifting apps treat 5/3/1 as "a workout you can build in our app." That misses the point. A real 5/3/1 tracker needs to handle the Training Max math automatically, present the right wave on the right day (3x5 vs 3x3 vs 5/3/1), warn you when your AMRAP reps suggest a Training Max adjustment, and let you toggle BBB, FSL, or Joker without rebuilding the program. We evaluated five iOS apps against those specific requirements.

If you want the one-line answer: Boostcamp is the deepest 5/3/1 tracker in 2026 and LiftProof is a close second with a meaningfully better Apple Watch experience. The full picture is below.

Methodology — what we evaluated and how we scored

Five criteria, each weighted by how much it matters to a serious 5/3/1 lifter:

• Native 5/3/1 template support (weight: high). Does the app ship a 5/3/1 template with Week 1 (3x5), Week 2 (3x3), Week 3 (5/3/1), and Week 4 (deload) configured correctly, with main-lift percentages calculated off your Training Max automatically?
• BBB / FSL / Joker variant support (weight: high). Boring But Big (5x10 at 50–60% TM), First Set Last (3–5 sets of 5–8 at the first set's working weight), and Joker sets (continuing past the prescribed top single when feeling strong) are the three Wendler variants serious 5/3/1 lifters use most. Native support means the app handles the supplemental percentages and rep schemes automatically.
• Auto-progression on TM (weight: high). After each cycle (every 4 weeks), the Training Max increases — typically +5 lb for upper body lifts and +10 lb for lower body. Does the app handle this automatically based on AMRAP performance, or expect you to do the math?
• Apple Watch logging (weight: medium). Can you complete a 5/3/1 session from your wrist? Wendler sessions are short — Watch logging that actually works saves real time.
• Price (weight: medium). Free-tier limitations, paid monthly cost, and lifetime pricing where offered.

We made our scoring rubric before knowing where apps would land. We make LiftProof; we acknowledge the conflict; we rank LiftProof #2 here because Boostcamp's overall 5/3/1 depth is meaningfully more developed.

1. Boostcamp — deepest 5/3/1 implementation

What it does well. Boostcamp ships multiple native 5/3/1 templates: the base 5/3/1 cycle, 5/3/1 with BBB, 5/3/1 with FSL, the Beyond 5/3/1 variants, and the more advanced 5/3/1 for Powerlifting. Each handles Training Max math, percentage prescription, AMRAP tracking, and deload weeks correctly out of the box. Joker sets are supported as an optional toggle on top sets. Auto-progression on TM after each cycle is built-in — you confirm the recommended increase or override it, and Boostcamp adjusts subsequent waves accordingly.

What it trades away. Boostcamp's depth introduces complexity. The 5/3/1 setup flow asks more questions than absolute beginners want to answer. The UI is functional but less polished than Hevy's or LiftProof's. Boostcamp's Apple Watch app exists but is not the central experience — if you want to log 5/3/1 from your wrist, you will find Watch logging slower here than on LiftProof. Account required; history lives in Boostcamp's cloud.

Best for: Lifters running 5/3/1 with BBB, FSL, or Joker variants who want native template support, and anyone who has ever built a Wendler spreadsheet from scratch and decided that was the last time.

2. LiftProof — best 5/3/1 + Watch combination

Disclosure: we make LiftProof. We rank ourselves #2 here because Boostcamp's overall 5/3/1 implementation is more mature, and we believe in transparent ranking. Where LiftProof beats Boostcamp on 5/3/1 specifically is Apple Watch logging — and the gap is not subtle.

What it does well. LiftProof ships a native 5/3/1 template with correct Training Max math, automatic wave selection (3x5 / 3x3 / 5/3/1 / deload), AMRAP tracking, and post-cycle TM adjustment recommendations. BBB and FSL are supported as supplemental schemes you can toggle without rebuilding the program; Joker sets are supported on top sets via an extend-the-set flow. The Apple Watch experience is the differentiator: you can run a complete 5/3/1 session from your wrist — Crown rep stepping, RPE input via tap, rest timer running on the Watch, set transitions auto-suggested. Privacy-first: no account required, on-device storage, no third-party SDK.

What it trades away. Our 5/3/1 implementation is narrower than Boostcamp's. We do not ship the full Beyond 5/3/1 variant set or the more obscure 5/3/1 for Powerlifting hybrid templates. If you are running a niche Wendler variant, Boostcamp will have it first. We do not have an Android app or cloud sync at v1.0.

Best for: Lifters running the standard 5/3/1 + BBB or FSL who want a Watch-first experience, and privacy-conscious lifters who do not want their training history in someone else's cloud.

3. Strong — basic 5/3/1, simplest setup

What it does well. Strong's 5/3/1 template is the simplest to set up of the apps on this list. You enter your maxes, the app calculates Training Maxes at 90%, and you run the cycle. For lifters who want 5/3/1 without thinking about variants, Strong gets out of the way fastest. AMRAP tracking is supported; TM increases after each cycle are prompted but require your confirmation.

What it trades away. Strong's 5/3/1 support is intentionally minimal. BBB, FSL, and Joker variants are not native — you can build them as assistance work but the app does not handle the supplemental percentages for you. Apple Watch app is light. Strong is the right pick when you specifically want 5/3/1-base-no-variants and value setup simplicity.

Best for: First-time 5/3/1 lifters who want the base program without BBB or FSL, and lifters returning to 5/3/1 after a layoff who want a clean restart.

4. Hevy — 5/3/1 as a routine template

What it does well. Hevy supports 5/3/1 via its routine template system. You can build a 5/3/1 routine and run it weekly, with set/rep prescriptions logged accurately. The set-log UI is polished and rest timers behave well. Hevy's program library includes a community-built 5/3/1 routine that handles wave variation.

What it trades away. Hevy does not treat 5/3/1 as a first-class program. There is no native Training Max math — you set your working weights manually each cycle. AMRAP tracking is supported via reps-in-reserve fields but not as a first-class 5/3/1 concept. BBB, FSL, and Joker variants require manual setup. If you are running 5/3/1 with any depth, Hevy will feel like you are doing the program in the app rather than with the app.

Best for: Lifters who run 5/3/1 as their loose programming structure but otherwise prefer Hevy's overall feel, and lifters whose primary need is a clean set-log experience.

5. Stronglifts 5x5 — only if you are also running SL 5x5 alongside

What it does well. Stronglifts 5x5's app does one thing well: it runs the StrongLifts 5x5 program with native autoprogression, deload handling, and a simple linear-progression flow. It is the best app for SL 5x5 specifically.

What it trades away. 5/3/1 is not native to Stronglifts 5x5. You can build 5/3/1 routines in the app but you will be working against its design philosophy, which assumes linear progression rather than waved percentages. We include it here because some lifters run SL 5x5 → 5/3/1 transition and want to keep their history in one app, but if 5/3/1 is your primary program, every other app on this list is a better fit.

Best for: Lifters transitioning from StrongLifts 5x5 to 5/3/1 who want a unified app — though we still recommend keeping them separate.

How LiftProof thinks about 5/3/1

We built LiftProof's 5/3/1 implementation around the question "what would Jim Wendler want this to feel like on an Apple Watch?" The answer was: less typing, more lifting. So we made the AMRAP set surface as a single Crown-driven number, the rest timer Watch-native, and the supplemental wave (BBB at 5x10 50% TM, for example) auto-prescribe without requiring you to do percentage math mid-workout. We made specific tradeoffs to keep that focus — narrower variant library than Boostcamp, no Beyond 5/3/1 hybrids at v1.0 — and we believe those tradeoffs are right for most 5/3/1 lifters. Read our head-to-head against Hevy for more on the philosophy.

What to look for if you're choosing your first 5/3/1 tracker

If you have not run 5/3/1 before and are choosing your first tracker, a few practical decisions narrow the field quickly:

• Decide whether you want supplemental work. Base 5/3/1 (no BBB / FSL / Joker) runs in any of these apps. If you specifically want BBB at 5x10 50% TM or FSL at 3-5 sets back-off, Boostcamp and LiftProof handle the supplemental percentages automatically; Strong and Hevy require manual setup.
• Decide whether you will use AMRAP sets. The final set of week 1, 2, and 3 in 5/3/1 is an AMRAP (As Many Reps As Possible) at the prescribed weight. AMRAP rep counts feed Training Max math — if you hit 5+ reps on a 1+ set, your TM is too low. Boostcamp and LiftProof use AMRAP performance to recommend TM adjustments; Strong tracks the rep count but does not adjust the TM for you.
• Decide whether your phone is in your pocket during squats. If yes, any of these apps works. If no — phone in the locker, Watch on the wrist — the Apple Watch logging gap between LiftProof and the rest is the deciding factor.
• Decide whether you care about cloud backup. Boostcamp, Strong, and Hevy cloud-sync your 5/3/1 history. LiftProof keeps it on-device with iCloud Backup as the resilience layer. Different tradeoffs; pick the one whose default matches your preference.

5/3/1 math the apps should handle for you

Running 5/3/1 properly requires the app to do specific math you would otherwise do yourself. Knowing what that math is helps you evaluate any 5/3/1 tracker you are considering:

• Training Max = 90% of 1RM. Wendler programs against the Training Max, not your true 1RM. The TM should be the weight you can reliably hit for 5 reps on a fresh day — typically 90% of your tested or estimated 1RM.
• Week 1: 3x5 at 65%, 75%, 85% of TM. Final set is AMRAP at 85%.
• Week 2: 3x3 at 70%, 80%, 90% of TM. Final set is AMRAP at 90%.
• Week 3: 5/3/1 at 75%, 85%, 95% of TM. Final set is AMRAP at 95%.
• Week 4: deload at 40%, 50%, 60% of TM for 5 reps each. No AMRAP.
• After each cycle: TM increases by +5 lb for upper body, +10 lb for lower body (unless AMRAP performance suggests slowing or speeding the progression).

An app that does this math for you removes most of the friction of running 5/3/1. An app that does not leaves you doing percentage math mid-warmup. Both Boostcamp and LiftProof handle all six of the above; Strong handles weeks 1-4 percentages but expects you to manage TM increases; Hevy handles none of it automatically.

Disclaimer

We make LiftProof. We try to evaluate fairly; we rank ourselves #2 here only where we can defend it, and we acknowledge that Boostcamp (#1) beats us on overall 5/3/1 implementation depth. 5/3/1 is a strength training program and the math is forgiving but not foolproof — if you are new to barbell training, working with a coach or experienced training partner during your first cycle is the best way to dial in your Training Max.
