This homepage is created for those who are in need of a tool to repair their FIT files. As a matter of fact activity files are sometimes corrupt and cannot be uploaded/imported into training diary software. 

The fit file repair tool which I have developed helps you to repair corrupted FIT files and rescue your valuable data.

The main features are:

• import of (corrupted) FIT, TCX and HRM files
• export as FIT, TCX or HRM file
• automatic detection and treatment of data corruption during the import
• modern user interface
• can be used as comfortable file converter for FIT / TCX / HRM file formats

The tool requires a PC with Windows. If someone is interested in developing a Mac or web version of my tool (s)he is invited to contact me and get all the support I can offer.
