I know it sounds silly, but I cannot use my device without this app & even wish apple also has similar feature for iphones.
Nokia's Z Launcher. 2 main features. Showing frequently used app & just [scribble the name of the app to open it](https://i.imgur.com/PNCx5qB.jpg) or a contact.
Sadly Nokia ditched it & no one else seems to have that 2 features.
