Best Apps for nSuns: 3 Workout Apps Compared (2026)

nSuns 5/3/1 is a high-volume linear progression program created by Reddit lifter 'nSuns' (Cody), built around 9 working sets on the top main lift and weekly AMRAP-driven progression. It's described in the community as 'Wendler in the front, Sheiko in the back'. Most workout apps treat nSuns as a custom routine you build from scratch. These three apps either ship the official nSuns template or are dedicated to nSuns specifically.

Why it's on this list

Boostcamp ships nSuns 5/3/1 as a free program with all four standard layouts built in: 4-day, 5-day, 6-day Squat, and 6-day Deadlift. You pick one, enter your Training Maxes, and the percentage table is filled in for you, no spreadsheet involved.

nSuns is genuinely hard to track by hand, and that is where the app earns its place. A single session can run 17 working sets across two barbell lifts, and the AMRAP top set moves your Training Max every week rather than every month. Boostcamp logs the full 9-set T1 ramp and the T2 work on one screen, records the AMRAP that sets next week's loads, and recalculates the table automatically. The plate calculator handles per-side loading on every set so you are not doing arithmetic between heavy attempts.

Getting programs like nSuns out of shared Reddit spreadsheets and into a real app is the reason Boostcamp was built, so it sits in the library next to 5/3/1, GZCLP, and 11,000+ others. When the aggressive weekly jumps eventually stall and you transition to a 4-week wave, your squat, bench, and deadlift history follows you. Pro adds the Strength Score, a per-muscle volume heatmap, and 20+ exclusive coach programs for $59.99/year ($4.99/month annual).

Best for: Lifters who want the official nSuns template (all 4 variants) with the weekly AMRAP and 9-set volume tracked automatically

Why it's on this list

nSuns 5/3/1 (by Jonas Reichert) is the most established dedicated nSuns app on the iOS App Store, with 4.9 stars and 4.9K US ratings. The app is built specifically for the nSuns 5/3/1 program and includes the 4-day, 5-day, 6-day Squat, and 6-day Deadlift templates. You enter your Training Max once and the app auto-programs every working set across the 9-set T1 scheme, with AMRAP results driving weekly Training Max progression.

Apple Watch and Apple Vision support are included. The pricing is free with optional in-app purchases. Among dedicated nSuns apps on the App Store, this is the only one with thousands of ratings, which makes it the standard recommendation when the strength community is asked for an nSuns-only tracker.

Liftosaur

Pricing
Free tier + subscription or lifetime (lifetime around $70 to $100)
Platforms
iPhone, Android, Web

Why it's on this list

Liftosaur ships nSuns LP as a pre-built program in its catalog: 'High-volume 5/3/1 variant with aggressive linear progression, 17 working sets per session across two barbell lifts.' The program runs on Liftosaur's standard tracker with the AMRAP-driven progression baked in, so you can start nSuns by selecting it in the library rather than scripting it from scratch.

What sets Liftosaur apart for nSuns specifically is Liftoscript, a plain-text scripting language for defining custom workout programs with arbitrary progression rules. If you want to run a popular nSuns hybrid like CAP3 or 4-day with Joker sets, or build your own variant with non-standard assistance work, Liftosaur is the only one of the three that supports that workflow directly. The web client lets you build complex programs on a laptop, then sync to mobile for the session.

Best for: Lifters who want a pre-built nSuns LP program plus the ability to script custom nSuns hybrids in plain text

Frequently asked questions

Why is Boostcamp ranked first for nSuns?

nSuns moves your Training Max every week off the AMRAP top set and stacks 9 T1 sets per session, which is a lot to run from a gym spreadsheet. Boostcamp ships the official template (all four 4/5/6-day layouts) free, logs the full session, and recalculates next week's percentages automatically. The dedicated nSuns app does this well too; Boostcamp adds the rest of the library and one continuous history for whatever you run after nSuns.

What should I run after nSuns?

nSuns is a late-novice to early-intermediate program. Most lifters run it until the aggressive weekly jumps stall, then move to a 4-week wave like 5/3/1 or into a hypertrophy block. Because all of those live in the same Boostcamp library, your squat, bench, and deadlift history and personal records carry from nSuns into the next program instead of resetting. That continuity is the practical advantage of a programs-library-plus-tracker over a single-program app.

Can I run nSuns on Android?

Yes. Boostcamp's nSuns 5/3/1 program runs on both iOS and Android, on the free tier, with the same automatic Training Max progression. This matters for nSuns specifically because the dedicated options skew iOS: the most established dedicated nSuns app (by Jonas Reichert) is iPhone, Apple Watch, and Apple Vision only. If you are on Android and want the official nSuns template with auto-progression, Boostcamp and the cross-platform Liftosaur are the main choices.

What is the difference between the 4-day, 5-day, and 6-day nSuns variants?

The variants differ in main-lift frequency. The 4-day template hits each of the four main lifts (squat, bench, deadlift, OHP) once per week with one T1 main and one T2 supplemental lift per session. The 5-day adds an extra day. The 6-day Squat variant trains squat 3x/week and deadlift 1x/week (with bench and OHP filling in the other days); the 6-day Deadlift variant flips that to deadlift 3x/week and squat 1x/week. All variants run the same 9-set T1 percentage scheme and AMRAP progression model. Boostcamp ships all four variants as configurable options inside the official nSuns 5/3/1 program; the dedicated nSuns 5/3/1 app also supports all four; Liftosaur ships the canonical nSuns LP template.

How does nSuns compare to standard 5/3/1?

Standard 5/3/1 (Jim Wendler) is a 4-week wave with conservative monthly Training Max increases and 3 working sets per main-lift session. nSuns 5/3/1 is a higher-volume, faster-progression variant: 9 working sets on the T1 lift per session (3 ramping sets followed by 6 back-off sets at lower percentages), with AMRAP-driven Training Max adjustments every single week rather than every 4 weeks. nSuns is generally considered late-novice to early-intermediate territory and is more demanding on recovery than standard 5/3/1. Boostcamp ships both the official 5/3/1 library and nSuns in the same free tier, so you can move between them across blocks.

Can I customize nSuns assistance work?

Yes on all three apps, but the workflow differs. Boostcamp's program editor lets you swap assistance exercises and adjust accessory volume in two taps, and the visual custom program builder lets you create your own nSuns hybrid from scratch with no scripting required. Liftosaur's Liftoscript supports arbitrary assistance rules via plain-text scripting (more flexible, steeper learning curve). The dedicated nSuns 5/3/1 app lets you customize assistance directly via in-app settings.
