What it does

A whole gym's worth of thinking, in your pocket.

IRONFRAME builds your week around your goal and equipment, then adapts every session from what you actually log.

Plans that adapt

Recovery-aware sessions pick what's freshest, double progression climbs reps then load — and when you stall for a few sessions it prescribes a planned deload instead of telling you to grind.

Recovery-awareDouble progressionAuto-deloads

Adaptive nutrition

Calorie & macro targets that recalibrate from your logged food versus your bodyweight trend. Scan a label on-device, and add your body-fat % for a sharper lean-mass estimate.

Questions

Frequently asked.

01Is my data really private?+
Yes. IRONFRAME has no accounts and no servers of ours — everything you log lives encrypted on your device (AES-GCM, with the key in the iOS Keychain). We run no analytics, no ads, and no third-party SDKs, so there is nothing to collect, share, or sell.
02Do I need an internet connection?+
No — the whole app works offline. GPS for outdoor runs and optional Apple Health writes use your phone’s own services; nothing is sent to us.
03How much does it cost?+
A 30-day free trial of everything, then IRONFRAME Pro at £5.99/month or £59.99/year through the App Store. Cancel anytime in your App Store settings.
04Which devices are supported?+
iPhone on iOS 17 or later, with a companion Apple Watch app, home-screen widgets, and a Lock-Screen Live Activity for your workout timers.
05Do I need any equipment?+
No. IRONFRAME is calisthenics-first — it builds around bodyweight and whatever you own (a bar, rings, dumbbells, bands), and scales exercises to your level.
