★ HOW IT WORKS

1. Pick your faction and artillery type at startup.
2. Type the distance to your target in meters.
3. For mobile artillery, also enter the vehicle's pitch in mils from the HUD (positive = nose up, negative = nose down).
4. Read the elevation in mils and dial it in. Fire.

The formulas are based on community-verified in-game measurements and trusted sources (artycalc.xyz, lonesomehotdog.com, l1tku/hll-spa-calculator and others), cross-checked against the current Hell Let Loose update.

★ WHY THIS APP

Built by a player, for players. Designed to live on your phone next to the keyboard during a session — big readable numbers, no clutter, no distractions, no waiting. Range limits per faction and vehicle are enforced, so you'll never send a round into the dirt because of a typo.

★ PRIVACY

No ads. No analytics. No data collection. No network permission. The only permission requested is WAKE_LOCK so the screen doesn't turn off mid-match.
