Sightline: Range Log & DOPE

You shot a good group. Now what? You squint at the target, guess the correction, and dial something close. Sightline ends the guessing. Photograph your target and the app marks your hits, measures the group, and gives you the exact clicks to move it to point of aim. All of it on your phone, and none of it on someone else's server.

ANALYZE YOUR TARGET
• Snap a photo or pick one from your gallery. AI marks the bullet holes the moment it loads.
• Calibrate to a known length and mark your aim point.
• Get group size in inches, cm, MOA, and mil, plus the exact elevation and windage clicks to zero.

YOUR ARMORY
• Every firearm gets a collectible card: optic, caliber, specs, and a precision grade earned from your real groups.
• Your level climbs as your round count grows.
• Maintenance intervals tell you when to clean before your rifle tells you the hard way.

AMMO INVENTORY
• Know what you have, what it costs per round, and when it runs out. The burn rate learns from your sessions.
• Scan a box barcode to restock in seconds.
• Keep a personal record of your handloads next to the factory lots you buy.

DOPE AND BALLISTICS
• Build a drop table for any distance with a G1 ballistic solver.
• Feed it wind, temperature, and altitude for a corrected firing solution.
• True it to your real observed drop, save named loads, and print a range card.

RANGE LOG
• Sessions roll up your groups, conditions, and cost.
• A trend line answers the only question that matters: are you getting better?
• Export CSV or PDF, or share a result card.

PRIVATE BY DESIGN
• No account. No sign-in. No internet required. Your data lives on your device and nowhere else.
• Optional passcode lock, stored only as a salted hash.
• Buy it once and it is yours. No ads, no subscriptions, no tracking.

Why Djeango: practical, fact-checked, and free of filler. Built by a technologist for people who measure progress in MOA, not likes.
