This app allows you to keep track of multiple percentages of correct/incorrect occurrences. This app was created to fill a specific need for speech therapists, but it's not domain-specific; if you're just trying to track how often something is done correctly, this app should work. Fully open-source (MPL-2.0-licensed) and written entirely in Swift, using SwiftUI.
