An iPhone tripod is a device used to securely hold an iPhone in place while taking photos or recording videos. It typically consists of three legs with adjustable height and angle, and a mount for the iPhone that can rotate and tilt to capture the desired shot. iPhone tripods are especially useful for taking stable shots in low-light conditions, capturing time-lapse videos, or taking selfies or group photos without the need for a designated photographer. They are compact and portable, making them ideal for travel and outdoor activities.
