You keep the programming
IronLedger never overwrites your plan. It proposes a target, names the rule, and leaves the decision with you.
// HEAD TO HEAD //
IronLedger vs JuggernautAI
A subscription powerlifting service that generates individualised programming, built around Juggernaut Training Systems methodology.
Verified September 2026All comparisons
// THE SHORT ANSWER //
Which one suits you?
Choose JuggernautAI if you want a coach-like service to write and adjust your powerlifting programming for you, including meet peaking, and you are willing to pay a monthly subscription for it. Choose IronLedger if you want to keep control of the programming and have the app be transparent about its suggestions rather than authoritative. JuggernautAI decides for you; IronLedger shows you its reasoning and lets you disagree.
// AT A GLANCE //
Side by side, no spin.

Three things we do better.
Free rather than $34.99 a month
This is the widest price gap in the category. IronLedger has no subscription at any tier.
Transparent by design
The progression engine is deterministic and documented. There is no model you cannot inspect deciding your training for you.
// WHERE JUGGERNAUTAI WINS //
Three things they do better.
Stated plainly, because a comparison that only flatters one side is not worth reading.
It actually writes your program
JuggernautAI produces individualised powerlifting programming and adapts it over a block. IronLedger will not do that for you, and is not trying to.
Meet preparation
Peaking for a competition is a first-class feature there. IronLedger has no meet-peaking logic at all.
Coaching pedigree
The methodology comes from an established powerlifting coaching organisation with a long competitive record behind it.
// WHO SHOULD CHOOSE WHICH //
Pick the one that fits how you train.
You compete or intend to, you want the programming decisions made for you by a proven methodology, and the monthly cost is worth it to you.
You want to run your own programming with a transparent assistant rather than an authority, and you do not want a subscription.
// DIRECT ANSWERS //
Questions people ask before switching.
Is IronLedger an AI coach like JuggernautAI?
No, and deliberately so. IronLedger uses a deterministic rule engine, not a model, and it recommends rather than decides. It does not replace a coach or a coaching service.
Can IronLedger peak me for a powerlifting meet?
No. There is no meet-peaking feature. You can run a peaking block you have written or imported yourself, but the app will not design one for you.

Try it alongside JuggernautAI
IronLedger is free with no trial to expire, so running a week in both costs nothing but the logging.
Download free on iOSOn Android, JuggernautAI is easier to get
JuggernautAI is publicly listed on Google Play. IronLedger is still in closed testing, which means joining a Google Group and opting in with the same account. That is a real disadvantage today, and it is the honest answer.
