About the product

IRON/OS is a pay-once Claude skill (£25) that builds your training around you. It interviews you on goals, equipment, schedule, injuries and current lifts, then writes a programme plus a single-file workout app you open on your phone to log sessions. Optional meal plan. Data stays on your device and there's no extra subscription or account (it runs on your paid Claude plan). Fitness guidance, not medical advice. 30-day refund.

Intertakt

interval timer

Biathlon is interval training in its oldest form: a full-gas loop, then perfect stillness — five shots taken on a breath you have just talked down from a sprint. The clock is never in the athlete's hands. The rhythm alternates without asking anyone to check anything, and a missed shot adds a penalty loop — the race goes on. Intertakt carries that alternation into HIIT, Tabata, EMOM and custom plans. A voice over your music delivers the timing — work, rest, where you are in the plan — with beeps counting down to each change and independent volumes for voice, beeps and music. The screen can stay off; calls and app switches interrupt nothing, and the session resumes from the exact second it stopped. The free tier is unlimited: 0 ads, unlimited sessions, 0 accounts. Premium is a one-time purchase, never a subscription — unlimited custom plans, session history, JSON export. Android, offline-first, in pre-release: coming soon to Google Play; waitlist and founding pricing are open at intertakt.com.
