How is it technically made?
Source code and support
The app is completely free: no trials, no demo versions, no limits, just download the latest version from the releases page of the Github repository or from the official website and install it. There's no catch, however it is not free to develop as not everybody maintains open source project. It takes time, requires paid code signing certificates and domains. You can make a donation through PayPal if you want.
Even more: you can always build it from sources yourself and add features that you may need if you have web development knowledge. The source code is available on GitHub.
