The most comprehensive ballistic solver ever built — 160+ features in one app. Independently verified against JBM Ballistics reference data.
Four solver models (3DOF, 4DOF, 6DOF, Pejsa), nine drag models, and every correction factor known to ballistic science. Validated with a 96-test physics suite covering 4 solvers, 8 drag models, and 6 corrections. Built for precision shooters, competitive marksmen, and trained professionals who demand accuracy at every distance.

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.
Apple Watch app, MIL/MRAD throughout, and a more accurate solver.
- **Apple Watch app** — quick calc, range card, and wind call on your wrist, synced from your iPhone solution.
- **MIL / MRAD everywhere** — the angular unit you pick in Settings now carries through the Virtual Turret, Turret Test, Scope Clicks, SDF table, and DOPE book. MIL-scope shooters get MIL across the whole app.
- **Single turret-unit choice** — the rifle editor now has one click-value field with a MOA/MIL picker.
- **More accurate firing solutions** — refined zero-atmosphere handling, and solutions for off-increment ranges (e.g. 375 yd) are now computed precisely instead of rounded to the nearest table row.
- **iPad** — your loaded rifle and load stay put when you switch apps and come back.
- **Range card PDF** — clearer column headers in dark mode.
- **Bluetooth meters** — "Apply to Calculator" now pushes live weather and rangefinder readings straight into your solution.
- **New content** — .22 ARC cartridge added; Arken Optics scopes and reticles added.
- **Load Development** — smoother and more reliable.
