// THE PRODUCT //

Everything the app does. Nothing it doesn’t.

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

// THE SHORT ANSWER //

What does IronLedger do?

It plans a training block, logs every set precisely, and explains what to lift next. You bring a program or pick a template, record load, reps and RPE or RIR on each set, and the app tracks personal records and estimated 1RM from what you actually did. When it recommends a load, it names the rule that produced it.

Change the session mid-session

Reorder, replace, add or remove exercises while the workout is running. The block stays intact for next week.

Form check on the set

Attach a short video to a single set, not just the session, so the clip sits next to the load it belongs to.

Rest timer that behaves

It pauses when the app is backgrounded, so a call between sets does not silently eat your rest.

// THE ENGINE //

Every recommendation shows its reason.

The engine is deterministic. It is not a large language model, and it does not generate your program. It applies one of three rules to what you logged and tells you which one it used.

Linear load

+2.5%

Add a fixed step to the working load when the prescribed reps are completed. The plainest rule, and the default for most templates.

RPE / RIR hold-advance

RPE <= 8

Advance while reported effort stays at or below the ceiling. Hold the load when it goes above, so a hard day does not compound into a missed week.

Percentage of PR

% e1RM

Target a percentage of your best single or estimated 1RM. Used by percentage-based blocks like 5/3/1, and recalculated as PRs move.

// OFF PLAN //

Some sessions aren’t in the plan.

Log without a plan

Start a freestyle session, pick lifts as you go, and log sets with the same fields as a programmed day.

Repeat a previous session

Pull any past session forward with its loads and sets intact, then adjust from there.

Save it as a routine

If a freestyle day is worth repeating, save it as a routine and it becomes part of your program list.

// CONNECTED //

Plays well with what you already use.

Availability varies by platform, release stage, permissions and device. Each entry says what it actually does rather than implying more.

Apple Health

Two-way

Writes completed strength workouts, and reads body weight so calorie estimates use a current number. Workout deletion has to happen in Apple Health itself.

iOS, with permission

Health Connect

Android

The Android equivalent path for workout sync, subject to Health Connect permissions.

Android, closed test

Strava

Export

Send completed sessions out to Strava if that is where your training log lives socially.

Where connected

Oura

Read

Reads your daily readiness score and offers a training recommendation based on it. To be clear about the boundary: it informs you, it does not change your programmed loads.
