About this app
Made for a clear purpose.
Fitpacket: Activity Files is a private activity-file workbench for opening FIT and GPX exports, reviewing tracks and records, and finding structural anomalies without uploading workouts.
KEY FEATURES - Local FIT and GPX file inspection - Container, checksum, and record inventory - Route, elevation, time, and sensor plots - Pause, gap, and timestamp evidence - Lap and record comparison - Clean supporting-record export - Inspect, Plot, Evidence, and Guide views - Forty original offline activity-file plates
ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated backend - Core tools and bundled reference material work offline - Work remains on device unless you deliberately import, share, or export through an Apple system interface
Parsed activity data is informational and may reflect device or file errors. It is not medical guidance or a certified performance record.
