iPi Recorder Release Notes

Here you can find history of recent versions of iPi Recorder.

iPi Recorder has built-in auto update functionality. Auto update feature is configured so that checks for update are made once per day. It helps to reduce the start time of the application. If you want to update ASAP — you can use the Check for Update button on home screen.

Note that both of these features require Internet connection. Alternatively (in case of troubles with auto update), you can download and run the updated installation program from direct link.
