What's New in Zima

2.0.50

November 5, 2026

Update: a new 3D Trajectory, new loads straight from the Pellet Database, and a round of improvements. 3D TRAJECTORY Laid out like the Reticle Simulator: the rifle and load at the top, Range, Wind and Zero at the bottom, and more room for the flight. Turn the phone on its side for a wider view. The lock on the range bar keeps the point you picked in the middle of the screen. 3D Settings can give this screen its own range, wind, zero and conditions while the Calculator stays as it is. The line of sight and the zero labels are easier to read, and Terrain stays off once you switch it off. PELLET DATABASE Use for a New Load on any pellet opens a new load filled in from the catalog, on your air rifle. Save takes you to Calculate with it. MEASURED DRAG CURVES "Just this solve" keeps your load and applies the curve to it. CATALOG CORRECTIONS When you save your own numbers for a catalog bullet, the correction is sent to us, as reticle corrections already are, so the catalog gets better for everyone. IMPROVEMENTS Calculate reopens on the rifle you used last. Search finds every tool a suite lists, like Rifle Trust Score. The chronograph box is empty and ready for the next shot. The Load Recommender says what counts toward a recommendation. The Shoot view writes units in your language, and the Shot Log reads "1 yard". At the largest text sizes, Calculate, the Bench and Zero Distance Explorer no longer cut or break words.

Shooters Bible

If you are looking for an all in one shooting and Ballistics app, look no further. This app has to be one of the most detailed and amazing shooting apps to this date. I have worked hand-in-hand with the developer to improve and add more features, and every update this app keeps getting better and better. If you find a bug, let him know and by the next update it is fixed if you want him to add a new feature, let him know, and he will most likely add it. I will never use any other shooting app besides this one.

App options and customer service

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.
