Project Summary
Project Overview
Pin-Sighter helps bowlers keep structured records of games, sets, equipment, lane conditions, patterns, and performance trends.
Bowling data is usually scattered across memory, paper notes, screenshots, or basic scoring apps. Pin-Sighter organizes those details into a reusable tracking system.
The app combines frame-by-frame logging, saved set history, bowler management, pattern tracking, and exportable reports in one local-first workflow.

Local-First Data
Pin-Sighter is built around local data storage. Bowling data is intended to stay on the user’s device unless they manually export it or share a backup file.
