Some applications that we use in smartphones are very useful, like the alarm clock. I have begrudgingly adapted to their quirks and privacy implications. I'd rather program my own versions, same for smartwatches.
Smartwatches are a godsend: I can set multiple alarms with chosen intervals, volume and ringtones, that never stop and place the phone easily at the right distance.
I could even improve on that and the same could be said of most phone apps. Recording and positioning are the most interesting features if they can be decoupled from big brother's eyes.
