Mode
Step 1 · Attacker
Who is shooting. Click any unit to swap the attacker — the target and its context stay put, so you can compare several of your units against the same enemy.
Step 2 · Target
The enemy unit you are attacking. Build one from any datasheet, reuse a defender you saved, or fuse an attached unit into one profile.
Step 3 · Context
Everything that changes the roll, in four layers from the widest scope down to the narrowest. All of it is optional — skip straight to the results if you just want the raw matchup.
Offensive Context
Defensive Context
Split Fire
Set each target’s own context, then assign every weapon to a target. The optimizer below can search the splits for you.
Expected Damage
Add as target B?

This will delete your login and all synced army lists and settings. Lists saved locally on your device are not affected. This cannot be undone.

IRONBUILT runs in any browser, but there is also a real Android app on Google Play. It is in closed beta, which means Google only lets people in one email address at a time. Ask below and we will add you.
  1. You give us the email on your Google Play account.
  2. We add it to the tester list, usually the same day.
  3. We email you the opt-in link. Open it on your phone, accept, and the app installs from the Play Store like any other.
It has to be your Google account email. Play grants beta access per Google account, so an address that is not the one signed in to your Play Store cannot be approved.
Google account email
Anything you want to add (optional)
Spot something wrong — bad wargear, math that doesn't add up, missing unit, UI glitch? Drop a short note and we'll take a look. Prefer email? Reach us directly at iron.built.app@gmail.com.
Corrections to game data are community contributions: IRONBUILT ships with no game data, and the dataset is built and corrected by its players. Accepted data suggestions are applied to the openly-licensed community dataset and recorded in its public contribution log.
Your email (optional)
Only used to reply if we fix this or need more detail. Never published. Leave blank to report anonymously.
Credit name (optional)
Shown publicly in the dataset's contribution log if this suggestion is applied. Leave blank to be logged as an anonymous community reporter.
