FAQ
Straight answers about AIron — how it compares, what you pay for, and how your data is handled.
How is this different from Fitbod or Hevy?
Fitbod builds workouts, Hevy logs them. AIron does both and notices your patterns (stalled lifts, poor recovery, injury signals). AI credits are included in every plan, so there is no separate AI bill and no API key to manage.
Do I need to pay for OpenAI/Anthropic separately?
No. AI credits are included in every plan — 5 a month on Free, 60 on PRO, 300 on ELITE. There is no API key to add and no separate bill from a model provider. If you run out, a one-time pack of 20 extra credits is 9.99 PLN (cheaper on PRO and ELITE) and those credits never expire.
Does it work for powerlifting/strongman/general strength?
Yes — that's the primary target. Not designed for cardio-first users. Weightlifting, powerlifting, bodybuilding, general strength: all core.
kg or lbs?
Both. Set once during onboarding, everything renders in your preference.
Can I import my history from Hevy/Strong/notes?
Yes. AIron reads the CSV export from Hevy, Strong, Strava, Google Fit and Samsung Health, detects the format automatically and maps the columns for you — there is a dry-run preview before anything is written, and an undo afterwards. Calendar → Import CSV. For anything else, paste your last week into chat and AIron parses it.
What if I stop paying?
Your data exports as JSON at any time. No lock-in. The free tier is not a trial and does not expire — your training and meal history stays, with no time limit.
