This app helps USPSA competition shooters to determine their estimated classifier rating on the range, immediately after shooting, without waiting for official monthly processing.
Simply select the classifier stage shot and the division used, and optionally enter your hit factor scored on the stage (points divided by time).
This app does not store or transmit any data of any kind. At present it does not have a self-contained updater, so it will not make any network requests at all. Because of this, it requires no special permissions to run.
