Convert Data Beta

This tool allows you to convert data between different fitness apps, making it easier to manage your workout information.

Just like how NextRep keeps all your data on device, all the conversion here happens solely on your device, in your browser, and no data leaves your device or is sent to any servers.

Currently, the apps NextRep and Strong are currently supported. If the app you use is missing, please send an email to [email protected], or open a GitHub issue or pull request and we can try and get it added.

Please note this tool is currently in beta, so some features may not work as expected. Please do not rely on this as a primary backup mechanism and check any converted data for accuracy.

Converting between some formats may result in loss of data. For example, Strong exports do not include workout templates, so converting data from NextRep to Strong will not include your templates.
