Most gun logs treat a firearm as one object with one round count. But a recoil spring, a striker, and a barrel don't wear at the same rate — and a single number can't tell you which one is due. Carbon Buildup tracks a firearm the way it's actually built: as an assembly of parts, each with its own service clock. WHAT IT DOES • Per-part service tracking — every part carries its own round and calendar interval, color-graded as it approaches service. Pre-loaded with manufacturer intervals for Glock, S&W M&P, Walther PDP, Canik, Beretta 92, CZ, Tanfoglio, and 1911/2011. • Service log — rounds between cleanings, lubes, and part changes. See what you actually run, not just what's due: average, longest, and current interval for every tracked item. • Chronograph and load data — velocity, SD, ES, and power factor tied to the specific gun that shot it. Barrel length and porting are recorded too, because a 4" carry gun and a 5.4" comp gun don't read the same. • Reloading recipes — bullet, powder, charge, primer, OAL, crimp, lot numbers, and cost per round. Estimate velocity in your own guns from bundled reference data. • Forecast and analytics — rounds fired over time, distribution by gun, and projected service dates based on your actual shooting pace. • Insurance rider PDF — export an itemized document with photos, serials, and declared values. Itemize down to the frame, slide, and barrel on custom builds. • Optic and light tracking — battery life, torque check intervals, and zero data. • Magazine tracking — spring cycles per set, so you know when followers are due. • Malfunction tracking — structured by type, per gun and per load, so patterns surface instead of getting lost in notes. • Photos throughout — firearms, targets, primers, malfunctions — with rotate and crop built in. • Full backup and restore — export everything to a single file and bring it to a new phone. YOUR DATA STAYS ON YOUR PHONE No account. No login. No cloud. Your safe, your serials, your photos — stored locally on your device and never uploaded to us or anyone else. We don't sell your data, we don't aggregate it, and we don't want it.
