There's a better option – G-Sight Laser Training Pro Review

It'll be okay for the casual dry firer with a single shot type laser module. For serious dry firers there is a better free app available. This would be great if you could reset from firing position, that's probably my largest complaint. The other being that with NLT SIRT pistol, it's easy to out shoot it. (Shoot faster than it can record hits)
