SG Timer GO | Affordable Shot Timer for Training & Dry Fire, Best Battery Life, Smart Sensor, Belt Quick Release, Bluetooth & Free Mobile app with Video Recording (Belt Quick Release Pocket Clip)

Timer works very well, especially being able to sue it for dry-fire. The Bluetooth connection between the timer and phone is really good and super stable. Changes you make in the app show up in the timer within a few seconds, and I haven’t had any issues with the connection dropping or being unreliable like a lot of other Bluetooth app enabled products these days. Being able to set up and track drills through the app is great. However, my only real gripe is the app seems a bit immature. The biggest thing being there doesn’t seem to be a way to delete anything. You can add gun configurations, drills, sets for those drills, etc. But you can’t delete anything you accidentally make. It would also be nice to be able to delete sessions, since I have a few odd sessions from when I was figuring the timer out.
