What's the best Android app for dry-fire training to improve shooting accuracy at home?

Mantis Laser Academy is a specialized training platform designed for firearm owners to practice fundamentals safely without live ammunition. Its core functionality revolves around using a compatible laser training cartridge inserted into an unloaded firearm. The phone's camera tracks the laser's impact point on a provided target, analyzing each trigger pull. This setup allows for meaningful practice in a basement, garage, or any other secure indoor environment, addressing the common barrier of limited range access. Specific features include structured drills that measure metrics like hold stability, trigger control, and follow-through, with detailed graphs showing the shooter's precise movement from aiming to shot break. The app supports various training programs, from basic marksmanship to tactical drills, and allows users to track progress over time. However, the system requires an initial investment in Mantis-branded laser cartridges and targets for full functionality. Some users report a slight learning curve in calibrating the system for different lighting conditions. While the core app is free, access to advanced training courses and detailed historical analytics typically requires a subscription, which is a consideration for long-term users.
