No laser bullet, no device or gadget! The app alone detects the dry-fired shots.

This one-of-a-kind app can detect precisely the deviation of the dry-fired shots from the center of the target (the bullseye). When users aim their firearms at the center of the target, the Bullz-I algorithms calculate how off-center the bullets would hit the target.

Always double-check that your firearm is unloaded before dry fire practice begins! Bullz-i makes it fun and safe to dry fire your unloaded firearm to improve your shooting accuracy and practice proper grip, stance, and sight alignment. Bullz-i provides you with instant feedback, by realistically displaying where precisely your shots hit the target on a smartphone screen. Bullz-i lets you conveniently share your dry fire practice results with friends and on social media.

Coming soon, Bullz-i will allow you to track your progress by saving the results directly to your phone. It will analyze your shooting results to identify errors, such as trigger jerking, heeling, and thumbing to provide you with the expert advice you need to improve your shooting skills without having to go to the range.

How it works

The Bullz-i app incorporates a unique technology based on three algorithms: image recognition with deep neural networks, audio peak detection algorithm, and a proprietary algorithm, able to calculate how off-center the dry-fired shots hit the target. All you need to run your Dry Fire practice session is to follow these simple steps:

1. Download and install the Bullz-i App on your iPhone;
2. Run the Bullz-i App;
3. Set your iPhone vertically by placing it against any supporting surface, with the iPhone’s camera pointing at you and with the digital shooting Target displayed;
4. Aim your unloaded firearm at the bullseye (the center of the target). The Bullz-I algorithms calculate how off-center the bullets would hit the target.

What is Dry Fire?

Dry firing is a great way to practice shooting skills. Dry firing is the practice of simulating the discharge of a firearm without any live ammunition. Members of the Armed Forces, police departments, and competitive shooters all use dry fire training to become better at hitting their targets. Dry Fire Training helps you to improve your shooting skills and accuracy. You can practice proper grip, trigger control, sight alignment, and breathing techniques. It can also help you to overcome any bad habits you may have developed, such as the anticipation of recoil.

NOTE 2: Dry fire poses no risk of damage to most modern centerfire firearms; however, it can damage rimfire weapons, where the firing pin in most designs will impact the breech face if the weapon is dry-fired. Because of this, precautions (such as the use of snap caps) need to be taken if such a weapon is to be deliberately dry fired.

NOTE 3: PLEASE BE SAFE!!! The dry fire should be done with NO AMMUNITION in or near the gun.

Why Bullz-i is better than its competition.

No laser bullet, no device or gadget! The app alone detects the dry-fired shots. Bullz-i is THE place to enjoy Dry Fire Training in the comfort of your own home, using the unloaded firearm & your iPhone.

Uses sound activation

Walking around, racking slide of ar-9 produced phantom shots. Turning off mic resulted in no detected shots. Seemed decently accurate, perhaps effective for pistol training drill at very short range.

Developer Response ,

Thank you for the feedback. Over the past few months, we’ve been hard at work creating major software improvements in detection accuracy. Our next and the biggest update yet is going to include the ability to calibrate Bullz-i algorithms specifically to your firearm. Soon you'll be able to go to the Settings > Select Your Gun and select whether it’s a revolver or semi-automatic, single or double action. This calibration minimizes false positives and substantially enhances the accuracy of dry-fire shot detection. Please check back soon for updates!

Excellent app!

Excellent app! Even if it’s underperforming at times it is getting better from release to release. One of a kind, truly feels history in the making! Proud to be a member of the Bullz-i family.
