What non Samsung apps do you use ?

Just curious how many people use different non Samsung apps on their Note 5 ?

- Keyboard ? I use Google Keyboard, I found the stock Samsung keyboard too cramped
- Text app ? I tried stock messages but didn't like it, so went back to Textra
- Themes ? I don't like the look of stock TW, so I went with the Material Dark theme
- Browser = Chrome
- Launcher = NOVA

Anyone else use different non Samsung apps ?
