### 5/5 — App options and customer service

*2026-05-21*

This is one of the best ballistic apps on the iOS platform. There are a multitude of features, something for everyone.  The customer service for this app has no competition, they are the best. Drop them a note, email what ever for changes, bugs, additions, they will get it done in days not months. I most likely will not use all the features, but for my hand loading and load development this app has that cover. Recommend to those that load develop.

## Version history (last 5 releases)

### 2.0.27 — 2026-08-18

Seven new languages, more free rifles, and ballistic coefficients that carry their drag model everywhere.

YOUR OWN RIFLE, FREE
Build a rifle of your own and keep one a friend shares with you — on top of the three starter rifles the app comes with.

SEVEN NEW LANGUAGES
Greek, Finnish, Galician, Hebrew, Hungarian, Icelandic and Kazakh, fully translated throughout the app.

COEFFICIENTS THAT KNOW THEIR DRAG MODEL
Every ballistic coefficient now travels with the model it was measured against — G1 or G7 — through saved loads, the BC ladder, every tool and the solver itself. Loads you already saved are tagged automatically.

VERIFIED CATALOG UPDATES
Bullet and reticle data now arrives cryptographically signed, so every update you install is authentic.

ALSO NEW
Custom drag curves join Ballistics Pro, alongside accuracy refinements across the calculator, the reticle simulator and the atmosphere model.

### 2.0.26 — 2026-08-07

A big accuracy and correctness pass — plus the app finally speaks your language on the screens you use most.

- **The reticle simulator opens ready to use.** It starts on a real reticle — the ACOG, with actual artwork — instead of a placeholder, remembers the reticle you last used, and your pinned favorites are now yours to edit. Dual-magnification optics like the Elcan snap between their real powers instead of pretending to zoom smoothly.
- **A rifle from the first second.** New installs start with a ready-to-shoot M4 profile, so the calculator solves and the simulator shows real holdovers before you've typed a thing. It's an ordinary profile — rename it, edit it, or delete it.
- **Holds all the way to the muzzle.** Setting the distance to zero now shows the hold dead centre instead of making the aiming dot vanish.
- **Clearer when something's missing.** No rifle selected? A small tap-to-choose note appears instead of a card blocking the reticle. A reticle that left the catalog now says exactly what's showing in its place.
- **Tips you can silence in one tap.** Every help card now has "Hide all tips" — reversible in Settings.

- **Much more of the app speaks your language.** The tab bar, the tool menus, every suite glossary, the onboarding tips, the upgrade screen and most of the calculator were showing English no matter what language you'd picked. They're translated now. Spanish (Spain) also gets the complete translation instead of a partial one. A handful of calculator input labels are still English — they're next.
- **Shooting light is honest about what it tells you.** The screen now says what it actually computes — civil twilight times — with a reminder to check your own state's regulations, because legal shooting hours vary by state, species, and method. The underlying sunrise/sunset math is more accurate too, and remote coordinates now use the right time zone instead of your phone's.
- **Fire and public lands is honest about what it knows.** Wildfire outlines are labelled as what they are — mapped incident areas, not legal boundaries — and the app no longer claims a restriction stage or tells you ammunition is permitted when it has no way to know. Always confirm with the managing agency.
- **Right numbers on the right screens.** The compact shooting view now reads out your selected distance. The reticle simulator gives dial and click counts in your rifle's turret unit. The multi-rifle table carries your full wind, cant, and Coriolis setup through to every rifle. Truing calibrates against your actual rifle and load.
- **Your data is safer.** A backup could overwrite a good iCloud copy with an empty one after a database problem. Saves that reported success before the write finished can no longer lose the record. Deleting one thing can no longer roll back unrelated edits elsewhere.
- **Load and bullet data stays consistent.** Switching drag models now updates the ballistic coefficient with it, and picking a new bullet clears the previous one's length and BC instead of quietly keeping them.
- **Training drill math corrected.** The lead-calculation drill's times of flight were about three times too short, so every answer it graded was wrong.
- **Faster, steadier 3D trajectory**, and it can no longer show one rifle's data labelled as another's.

### 2.0.25 — 2026-07-08

Edit your rifles, bulk-import your reloading components, and sharper accuracy throughout.

- **Edit any rifle.** Tap the pencil on any rifle in My Armory to update its setup — barrel, twist, scope, reticle, loads, zero conditions, and more. Locked rifles stay protected.
- **Bulk import & export for reloading components.** Have hundreds of powders, primers, bullets, or brass? Import your whole inventory from a spreadsheet instead of one lot at a time. Export any component tab to CSV, or download a blank template to fill in — right from the inventory screen.
- **Tell us what to track.** Every Reloading screen now has a quick way to request a field or section you'd like added.
- **Smarter DOPE widget.** The home-screen DOPE widget shows your holds in your scope's unit — MIL or MOA.
- **Sharper and more reliable** across the calculator, rifle profiles, the reticle simulator, and the reloading suite.

### 2.0.24 — 2026-07-05

v2.0.24
Sharper accuracy, a cleaner Results screen, and corrections that stay put.

- **Second-focal-plane holds.** The scope simulator now places holds correctly for second-focal-plane optics at any magnification, not just at their reference zoom.
- **Corrections that stay put.** Your custom ballistic-coefficient overrides stay linked to the right bullet through every future bullet-database update.
- **A cleaner Results screen.** CSV and Excel export plus compute time are front and center, and the trajectory chart now frames your data tightly with no wasted space.
- **First-launch polish.** The privacy welcome screen now matches the rest of the app in every appearance.
- Dozens of accuracy and reliability improvements across the calculator, reticle tools, training drills, and backup & restore.

v2.0.11
Build your own drag curves from real downrange data, import your trued bullets in bulk, and connect more chronographs.

- **Doppler Drag Curve builder.** Turn downrange velocity measurements into a measured Cd-vs-Mach curve specific to your exact bullet and load — more faithful than a single BC. Capture live over Bluetooth from a LabRadar, import a Series CSV, or enter the numbers by hand. The result is shown against a G7 reference before you save it, then links straight to a bullet so it auto-applies.
- **More accurate custom curves.** Trajectories that use a custom or Lapua Doppler drag curve are now computed with the projectile's true drag, correcting a small bias — your numbers tighten up automatically.
- **Bulk bullet import.** Import per-bullet BC corrections from a CSV (with a downloadable template), link a custom drag curve to any bullet, and wire a Lapua Doppler profile to a bullet in one step.
- **More Bluetooth chronographs.** Added FX chronograph support and Athlon Rangecraft, plus a diagnostic Bluetooth Explorer for capturing data from other devices.
- Connection reliability improvements across all Bluetooth devices.

### 2.0.9 — 2026-06-17

v2.0.9
- More dependable iCloud restore when setting up on a new device.
- Stability and performance improvements.

v2.0.7
Sharper firing solutions and a smoother experience across iPad, CarPlay, Apple Watch, and the Reloading Suite.

- **Custom drag curves now apply everywhere.** Lapua Doppler and custom Cd-vs-Mach curves now feed every solver — drop tables, density-altitude cards, the trajectory simulator, rapid engagement, and multi-target solves all honor your attached curve.
- **Siri "Start a Range Trip" opens the editor on iPad too**, pre-filled and ready, just like on iPhone.
- **CarPlay navigation is steadier** — tapping a new range while a route is still loading keeps the latest destination on screen.
- **Reloading inventory polish** — component edits keep your widgets current, deletions stick, and the editors guard against invalid weights, dimensions, and prices.
- **Apple Watch sync reliability** improvements.

v2.0.0
The biggest update we've ever shipped — seven new workflow hubs, the Reloading Suite, the Range School training system, on-device AI Insights, and automatic backup that now covers every piece of user data.

### Seven new workflow hubs

- **Range Day** — session planner, live shot tracker, post-session trend analysis.
- **Armory** — structured inventory for rifles, optics, mounts, suppressors. Maintenance logs, loadout kits, per-optic mount + zero history.
- **Hunting** — hunt planner, hunt log, trophy records, GPS scouting.
- **Competition** — match planner, live score tracker with stage breakdown, hit-rate trends.
- **Military / LE** — mission planner, deepened anti-materiel + barrier data, TAK broadcast, encrypted CoT storage (Professional Acknowledgment required).
- **Analysis** — cross-suite dashboard, drill performance over time, predicted vs actual DOPE drift detection.
- **AI Insights** — on-device AI via Apple's Foundation Models (iOS 26 + iPhone 15 Pro). Rule-based fallback on older devices. No data leaves your phone.

### Reloading Suite

Six sections: Develop (ladder + OCW node detection), Track (per-lot ammo + components), Test (chrono manager), Records (Saved Load library), Reference (cartridge/brass/primer/powder DBs), Training. 24 visibility toggles with 4 layout presets.

### Range School — long-range training

Tier 1 of a five-tier skill system. 61 drills across 6 pillars (Marksmanship, Positions, Wind Reading, Range Estimation, Scope/Optics, Equipment). 290-term searchable glossary. Quiz mode. Failure-analysis library. Two training plans: First 30 Days + PRS Prep 12-Week.

### Backup now covers everything

Every rifle, load, zero, shot log, DOPE entry, range day, hunt record, match plan, mission log, AI insight, custom reticle, custom bullet override, suppressor — all of it round-trips through iCloud Drive. Restore on a new phone in one tap. Free for everyone.

### Cross-cutting

Unified Rifle Dashboard. Onboarding Suite Picker. Apple Watch hubs for Range Day / Armory / Hunting / Competition. Four new home-screen widgets. Live Activity on Dynamic Island. Four new Siri Shortcuts. Range School cross-links from every suite hub.

### Engine accuracy

Zero-atmosphere BC ratio correction. Interpolated drag-table lookups. G1, G2, G5, G6, G8, and GS drag tables replaced with canonical JBM-verbatim values — some user-tuned G1 BCs may now over-predict; re-verify against real point of impact.
