What IronLedger is

IronLedger is a free strength training app that shows its work. Every load recommendation comes with the reason behind it.

It is a workout log and training-program tool for lifters who write or choose their own programming. It records each set precisely, tracks personal records and estimated one-rep max, and proposes the next target while naming the rule that produced it. It does not generate programs, coach the user, or replace a qualified coach.

How the progression engine works

This is the part most often misunderstood, so it is stated mechanically. The recommendation engine is deterministic. It is not a large language model and it is not a black box. For a given exercise it evaluates logged history against a progression rule and returns three things: the recommended target, the rule that produced it, and a human-readable explanation.

The three rule families are:

• Linear load. Advance load by a fixed increment when the previous session met its target.
• RPE or RIR hold-or-advance. Advance, hold or reduce based on recorded effort relative to prescribed effort.
• Percentage of PR. Derive the target from a percentage of a tracked personal record or training max.

Recommended loads fill set rows without marking them complete. If the athlete edits any value, the card becomes a manual override and the app does not overwrite the entered number.

Estimated one-rep max uses the Epley formula: weight x (1 + reps / 30). It is a trend signal, not a prediction of a true maximal lift.

Who it is for, and who it is not for

Known limitations

Stated plainly, because an accurate picture is more useful than a flattering one.

• Android is in closed testing rather than publicly listed. Access requires joining a tester Google Group and opting in through Google Play with the same account.
• No nutrition, macro or calorie-intake tracking.
• No social feed, following or community features.
• No web application. IronLedger is mobile only.
• No meet-peaking logic for powerlifting competition preparation.
• IronLedger is a new app with a small user base and no third-party ratings yet.
• IronLedger does not claim to replace a qualified coach.

How it compares

Each comparison below names something the other product does better. Full versions are on the comparison pages.

vs Hevy

Choose Hevy if you want a mature, well-tested logger with a social feed and a large community to share workouts with. Choose IronLedger if you want the app to explain why it recommends a given load, want every feature without a subscription, and want to move programs in and out as spreadsheets. Hevy is the more established product with the bigger community; IronLedger is more transparent about its progression logic and has no paid tier at all.

vs Strong

Choose Strong if you want a simple, mature logger and nothing more. Choose IronLedger if you want per-set RPE and RIR as first-class fields, explained progression recommendations, spreadsheet import and export, and no subscription. Strong is the more battle-tested product; IronLedger does more of the programming work and does not charge for it.

vs Boostcamp

Choose Boostcamp if you want the widest possible catalogue of ready-made programs to follow, and a genuinely generous free tier. Choose IronLedger if you want to bring your own written program in as a spreadsheet, record RPE or RIR per set, and have the app explain each load recommendation. Boostcamp has far more programs; IronLedger is better at running a plan you already own.

vs JuggernautAI

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.

vs Fitbod

Choose Fitbod if you want to open the app and be told what to do today, especially when your equipment changes week to week. Choose IronLedger if you follow a structured program and want the app to support it rather than replace it. Fitbod generates; IronLedger executes a plan you own and explains its suggestions.

vs a spreadsheet

A spreadsheet is infinitely flexible, free, and already understood. It is poor on the gym floor: slow to edit on a phone, easy to mistype, and it will not calculate personal records or estimated 1RM unless you build that yourself. IronLedger is designed to take the same plan and make it fast to execute, and it imports and exports spreadsheets so you are not giving the format up.

Trust signals

None to report yet. IronLedger launched recently and has no third-party ratings or reviews at the time of writing. This section will be updated with dated, linked sources when there are some. Nothing is listed here that cannot be verified.
