## What is FIT File Viewer & Repair?

Open, inspect, diagnose and repair FIT activity files directly on your iPhone.

FIT File Viewer & Repair is designed for athletes, developers and anyone who needs to inspect workout data stored in FIT files. Review activity summaries, GPS routes, charts, laps, sessions and detailed file information without uploading your activity files for analysis.

OPEN FIT FILES

Import compatible .fit files from Files, Downloads, email attachments, cloud storage and other supported apps.

ACTIVITY OVERVIEW

Quickly review important workout information including:

• Activity duration
• Distance
• Record count
• Sessions
• Laps
• Activity summaries
• Available sensor and workout data

GPS ROUTE VIEWER

View recorded GPS tracks directly on a map.

See the activity path and review available start and finish locations for supported FIT files.

WORKOUT CHARTS

Visualize available workout data with built-in charts.

Depending on the data stored in the FIT file, supported metrics may include heart rate, speed, cadence, altitude and other activity records.

LAPS & SESSIONS

Inspect decoded lap, session and activity summary information in an easy-to-read format.

FIT FILE DIAGNOSTICS

Analyze FIT file structure and identify supported problems such as malformed or incomplete activity data.

The app reports detected issues clearly so you can understand whether a file appears valid, unsupported or potentially repairable.

FIT FILE REPAIR

Repair supported FIT file issues and export a corrected file when a safe repair is available.

Not every corrupted or unsupported FIT file can be repaired. The app avoids modifying activity data when a safe repair cannot be determined.

RECENT FILES

Quickly reopen recently inspected FIT files without repeatedly browsing your file library.

PRIVATE, ON-DEVICE ANALYSIS

FIT file contents are processed locally on your device and are not uploaded to a remote server for analysis.

Large files are opened safely using on-demand processing where supported.

FIT File Viewer & Repair is useful for:

• Running activities
• Cycling activities
• GPS workout files
• FIT file validation
• FIT file inspection
• Recovering supported damaged activity files
• Reviewing workout records outside the original fitness app
