Frequently asked questions

Is the shot timer free?

It's part of Caliber Pro: $4.99/month, $29.99/year with a 14-day free trial, or $99.99 once for lifetime access. Caliber's other shooting tools are free.

Does it work at an indoor range?

Yes, but loud bays with other shooters can trigger false shots. Use the sensitivity setting, and keep the phone close to you.

Is dry-fire practice safe?

Only with an unloaded firearm, checked twice, with no ammunition in the room, pointed in a safe direction. Follow the four safety rules every time.
