To sign up for Gutter App™, users can go to the Apple App Store, download the app, and agree to the monthly subscription charge before accessing the trial period. During the trial, users can use all of the app’s features to see how it can benefit their business. If Gutter App™ is not the right fit, users should cancel their subscription before the trial period ends to avoid being charged. However, if they find the app useful, they can continue using it by paying the monthly subscription fee after the trial period has expired.
