Unfortunately, as Task Coach is actively developed, the developer team are working on new features regularly. This means that Task Coach does contain a few bugs. This being the case, the developers do advise you to make backups of your work regularly.
Task Coach is also available for Windows and GNU/Linux. There is also a companion iOS app.
