I'm looking for a simple free piece of software that has a nice GUI to keep a list of, for example:
- their serial numbers,
- purchase dates,
- warranty periods,
- owner's comments.
It should be free, preferably FOSS. Also, it would be great to have clients for Windows, Linux, Android and some kind of synchronization between them.
Of course, I can write this info into a text file, but that't not fancy. A business inventory system will be to much.
