Project Overview

Purpose

Pin-Sighter helps bowlers keep structured records of games, sets, equipment, lane conditions, patterns, and performance trends.

Problem

Bowling data is usually scattered across memory, paper notes, screenshots, or basic scoring apps. Pin-Sighter organizes those details into a reusable tracking system.

Approach

The app combines frame-by-frame logging, saved set history, bowler management, pattern tracking, and exportable reports in one local-first workflow.
