Pro Straightforward SMS manager
In addition to allowing you to send and see incoming messages using an intuitive interface on a computer, the app also allows you to manage contacts.
Pro Supports cross-device notification mirroring
SMS and app notifications as well as incoming call notifications are mirrored on the connected devices.
Pro Open source
Pro Free and easy to work with
Pro Frees one from other parasitic, eternal wallet bleeding software
Good software is written once and well, and then sold with a perpetual license. Happy users are welcome to buy new versions in future years or continue using the one they already bought. Toxic business models feature CEO's explaining the juicy but unwarranted revenue stream they will create with gullible user's wallets by charging monthly/annual fees for software that should have been written once, paid for once. Thanks to KDE we can choose the former and are free to reject the latter.
Pro Works with Win10 Laptop and Android phone
Pro Works perfectly with Gnome using the GSConnect extension
Cons
Con Considerable delay when sending SMS messages via computer
