Shot timer Question…

Torn between the Shooters global and the Commander Oled. Anyone have experience with both? Does the SG connect to Practiscore?

I dont mind the price difference but the phone timer in the drills app sucks, and the app Itself seems like overkill with all the VR stage building ect. Cool but i dont see myself using that part. I will however use the hammer fall and striker and airsoft for dry fire. Curious to see what the hive mind thinks of either one.
