Professional Target & Reaction App for Precision Training Train target accuracy, reaction speed, and trigger discipline under realistic conditions. Choose distances from 25 to 300 meters, adjust target sizes (e.g., biathlon targets 4.5 cm / 11.5 cm or a classic 10-ring target), and analyze the last milliseconds before the shot is released. The system detects trigger jerk, minimal axis deviations, and instabilities during the holding phase. You receive precise feedback on shot grouping, reaction time, and movement stability. Ideal for sport shooters, rapid fire disciplines, biathlon, and tactical training — safely usable with a training weapon or replica. Green on target does not automatically mean a hit. The decisive moment is the instant of trigger release. The app displays multiple possible target positions. Users must quickly recognize which target becomes active and react accordingly. This trains perception, orientation, and decision-making. A special feature of the system is digital spatial target training. Targets can be defined at fixed positions in space and only appear when the smartphone is pointed in the correct direction. This creates exercises in which users must search for invisible targets in the environment, identify them, and react quickly. This not only trains reaction time, but also spatial awareness and rapid situational recognition. The training concept is inspired by well-known reaction and target exercises used in sports training. Movement patterns, timing, and orientation can be practiced early and in a playful way. Digital Target System O-SpeedStrike uses a digital targeting system where target points are defined in physical space. Targets are initially invisible. They appear on the screen only when the smartphone is pointed in the correct direction. This creates dynamic training for orientation, attention, and fast decision-making. Within the app, different training situations can be configured, for example various distances or multiple target positions. Controller and Accessories O-SpeedStrike can be controlled directly via the smartphone. Alternatively, Bluetooth controllers can also be used. These controllers serve solely as input devices for the training exercises and make fast reaction drills easier. The Bluetooth controller can take different forms. In addition to the smartphone itself, separately available accessory devices with smartphone mounts can also be used. Such controllers are commercially available and can be connected to the app via Bluetooth. This flexible control system makes the training suitable for simple reaction drills as well as dynamic training scenarios indoors and outdoors. Features • Multi-target reaction exercises • Spatial target search and orientation • Hidden target positions in the environment • Adjustable distances and difficulty levels • Reaction time measurement • Support for external Bluetooth controllers Training Effect O-SpeedStrike combines orientation, reaction, and precision in a fast digital training format. The app helps improve attention, timing, and coordination. The spatial target system creates varied training for concentration and fast decision-making. A compact training system for reaction, orientation, and coordination.
