// THE PRODUCT //

Everything the app does. Nothing it doesn’t.

IronLedger is a free strength training app that shows its work. On the built-in programs, 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 on a built-in program, it shows where the number came from and why.

// LOGGING //

Labels only: there are no fields to log time, distance or intervals. Reps written with a + make an AMRAP set.

Change the session mid-session

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

Rest timer that behaves

It keeps counting when your phone is locked, and alerts you at zero if notifications are allowed.

// 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. On five built-in programs it looks at what you logged last session and tells you where each recommended load came from and why.

Add a step

+2.5

After a session where you hit every prescribed rep and the effort was easy (RPE 7 or below, RIR 3 or more, or no effort logged), it adds 2.5 kg or lb, in your unit.

Hold the load

RPE 9+

After missed reps or a hard session (RPE 9 or higher, or RIR 0) it holds the load, so a hard day does not compound into a missed week. Anything in between holds too.

Where it runs

5 programs

Starting Strength, 5/3/1 Boring But Big, PHUL, Push/Pull/Legs Strength Bias and Upper/Lower Powerbuilding. Challenge to Change and the guided 5/3/1 set-up work from your training max instead.

// 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.
