How it works
Built between sets
I train five days a week, and every tracker I tried wanted more attention than the workout itself. Ironbor comes from those gym floors: pick a routine, tap your reps in, and get back to the bar. It quietly keeps score — your records, your weekly volume, your streak — so progress is something you see, not something you bookkeep.
Your routines 3 ready-made templates, plus your own — start training in one tap.
Stats & records Personal records and weekly progress, quietly kept.
Rest timer A Live Activity countdown right on your Lock Screen.
Features
What it does
Fast set logging
Reps, weight, done — logging a set takes a tap, not a form.
Workout templates
Three ready-made routines out of the box, and an editor for your own.
Personal records
PRs are spotted and saved automatically as you train.
History & progress charts
Weekly volume, workouts per week, and each exercise's trend over time.
Lock Screen rest timer
A Live Activity counts your rest down without unlocking the phone.
Kilograms or pounds
Metric or imperial, switched in a setting — history converts with you.
Under the hood
How it's built
Native iOS in Swift and SwiftUI, built for iOS 26. Instead of view models, each feature is a small unidirectional loop — @Observable state, signals, and focused use cases — with dependencies injected via swift-dependencies so everything stays testable. Workouts live in SwiftData, the rest timer runs as an ActivityKit Live Activity, and progress is drawn with Swift Charts.

FAQ
Good to know
Yes — the core tracker is free: log your workouts, use the three ready-made routines plus up to three of your own, and keep your records and streaks. An optional Ironbor Pro subscription (monthly or yearly) adds unlimited custom routines, detailed stats and trends, the full calendar history, and animated exercise demos.
Yes, and only where it earns its place: Ironbor writes your workouts to Apple Health and reads your body weight back. It's optional, and you decide whether to grant access.
iPhone, on iOS 26 and newer. The rest timer lives on the Lock Screen as a Live Activity.
Ironbor is on the German App Store for now — you can read the listing from anywhere, but installing it needs a German account. If you'd like it in your country, tell me: knowing where people actually want it is how I'll decide where to open it up next.
