Thank you for using AmmoDB. Your care with ammunition and equipment deserves credit. Whether you shoot, hunt, or collect, AmmoDB gives your records a practical home on iPhone and iPad. Keep an ammo inventory, firearm log, range journal, and reloading notebook together. Check stock, storage, costs, and ammunition use. Records work offline, with no app account required. AMMUNITION INVENTORY - Record ammo names, manufacturers, caliber details, grain weights, containers, dates, status, and notes. - Track boxes, rounds per box, loose rounds, rounds used, and rounds remaining. - Review purchase costs, total cost, cost per round, and percentages used or remaining. - Add photos to identify a box, batch, or storage location. - Organize stock by safes, shelves, cabinets, ammo cans, or range bags. - Search your inventory, reuse saved ammo-name presets, and duplicate similar records. - Keep dated usage history with notes for practice, training, testing, or field use. FIREARMS AND STARTER MODELS - Keep firearm identification, serial numbers, measurements, purchase details, notes, and photos. - Start with 169 model entries covering 61 firearm models and 67 calibers and gauges. - Choose from several models for popular calibers, or enter your own details. - Search models at the top of the chooser, filter by firearm type or caliber, and sort by name, type, or caliber. - Link firearms to your ammo records, range sessions, and ladder tests. - Review and edit starter details against your own firearm. Templates fill identification fields only. RANGE JOURNAL AND CHRONOGRAPH - Log ammunition used in named range or field sessions and keep round counts current. - Enter or paste chronograph readings in feet per second or meters per second. - Review average velocity, minimum, maximum, extreme spread, and standard deviation. - See shot-by-shot velocity graphs and daily ammunition use. - Save target photos, measure groups, and compare group sizes in MOA. - Keep session notes and return to the firearm and ammo records behind them. HANDLOADING RECORDS - Track powder, primers, and brass with dated stock additions and use. - Record brass firing counts and preparation stages by batch. - Save ladder test observations, measured charge weights, velocities, groups, and notes. - Review component history and graphs of your recorded test results. COUNTS, COSTS, AND REPORTS - Review inventory stats by ammunition and storage location. - Compare counted rounds with your chosen allowance maximum. - Open readable ammo records and share a PDF report of matching records. - Browse and sort a spreadsheet-style inventory with Ammo+ Pro. CALCULATORS AND REFERENCE - Estimate trajectory, wind drift, velocity, and energy with the ballistic calculator. - Use twist rate and recoil calculators, plus an MOA and mil converter. - Save ballistic results and share calculations when you choose. - Browse a searchable ammunition reference with identification notes and source links. Choose optional startup protection with an app PIN, or supported Face ID or Touch ID with PIN fallback. Inventory and photos stay in local app storage unless you share them. Free access includes three ammo records and three locations. Ammo+ Pro offers unlimited records, locations, and calculator use, plus Spreadsheet and CSV/JSON inventory sharing. Choose monthly or lifetime access. Inventory exports exclude photos and separate firearm, range, and reloading records. Calculators provide estimates, and references are for identification.

Verdict
The clearest difference is price: AmmoDB at Free against BulletCalc3's $0.99. AmmoDB also leads on rating (5.0 vs 3.0) and update cadence (every 2 weeks vs every 2 months). BulletCalc3's advantage is iOS requirement (15.6 vs 17.6). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
