Athlon Ballistics vs BenchLog

Athlon Ballistics is the companion app for Athlon Optics shooters. Use it with your Athlon chronograph, with supported Athlon thermal scopes and clip-ons, or on its own as a ballistic calculator. CHRONOGRAPH • Connects to your Athlon chronograph over Bluetooth, automatically when it is near. • Live screen: see the velocity of every shot as you fire, with average, extreme spread (ES), standard deviation (SD), maximum, minimum and energy. • Name each session, add notes, and link it to a rifle and a bullet. • Compare and merge sessions. • Sessions sync to your account and come back on a new phone. • Export sessions to a spreadsheet and share them. • Update the chronograph firmware from the app. BALLISTIC CALCULATOR • Firing solutions with G1 and G7 drag models. • A library of factory cartridges and bullets. Add your own bullet with its BC, weight and length. • Rifle and bullet profiles with sight height, twist rate and zero distance. • Live local weather for the solution, or enter the conditions yourself. • Ballistic charts with your own ranges and steps. Export them to a spreadsheet. ATHLON RETICLES • See your hold on the real Athlon reticle for your scope. ATHLON THERMAL SCOPES • Quick Connect: pick your supported Athlon thermal scope or clip-on, including the new Athlon DCM, and the app joins its Wi-Fi network for you. • Live view from the scope. On supported scopes, take photos and videos that save to the scope's card, then save them to your phone from the scope's album. • Send rifle and bullet profiles to the scope's ballistic calculator. On DCM scopes, holdover marks come from your profiles. • Change reticle type and color, and set BDC holdovers on supported scopes. YOUR DATA • Sign in with email, Google or Apple. Profiles and sessions stay with your account. • Imperial and metric units. English, German, French, Spanish and Italian. • Delete your account from the app at any time.

BenchLog is a reloading journal built for handloaders who take load development seriously — and who want their data to stay on their own device. Log every load, track what each charge actually does downrange, and work up to the load your rifle likes best. No account. No cloud. No subscription. ALREADY KEEP A SPREADSHEET? BRING IT. Import your load log from CSV. Map the columns yourself — BenchLog shows sample values from each one so you can tell them apart — and check the preview before anything is saved. Headers split across two rows are handled. Columns it has no field for go into the load's notes instead of being dropped. Nothing is written until you say so. LOG YOUR LOADS • Record caliber, bullet, powder, charge, primer, brass, OAL, CBTO and notes • Duplicate a load to work up the next charge in one tap • Version history keeps every step of a workup • Yellow flag when a charge tops your own logged max TRACK EVERY RANGE SESSION • Enter velocities by hand or import a chronograph CSV • No chronograph? Enter the number of rounds fired — inventory and barrel round count follow it • Live average, SD and ES as you go • Group size, MOA, distance, weather and a keeper / retest / reject verdict • Photo of the group KNOW YOUR BARREL • Round count for every barrel, built from the sessions you already log — free • Started mid-life? Enter what the barrel had on it before BenchLog • Sessions on loads without a barrel are never folded into the count • Sessions with no round count are marked, not silently counted as zero • PRO: cleaning log — set "clean at N rounds", see the count since the last cleaning, and keep every cleaning with the round count it was done at SEE YOUR LADDER • Charge vs. velocity chart across a workup • Seating depth test: switch the axis to CBTO and chart group size against cartridge length • Tap any point for its MOA and distance • SD at a glance to spot the flat spots KNOW YOUR INVENTORY • Track powder, bullets, primers and brass with cost • "Rounds left" forecast from your average charge • Low-stock flags EXPORT & BACK UP • Printable PDF load book • CSV export of loads, sessions, components and barrel cleanings • Full backup to a single file — and restore it anytime BUILT RIGHT • 100% offline — everything works at the range with no signal • No account, no tracking, your data never leaves the device unless YOU export it • Free forever: your range log, group measurement, ladder charts, inventory, barrel round count, import and export, and your first 10 loads • One-time purchase — BenchLog Pro — unlocks unlimited loads, the barrel cleaning log, the season summary and the result card, with more Pro tools as they land. No subscription, ever. BenchLog stores YOUR records only. It is not load data. Always verify charges against a current published reloading manual. Start low and work up. You are responsible for your loads.
