None at all.
My 'phone is not linked to the Internet but even if it was, the less clutter and fewer gimmicks on it, the better.
I have sometimes seen friends' smart-phones' home-screens, and watched the owners flick through page after page of symbols for one programme or link after another... dozens of them.
By comparison, my computer has apart from Microsoft WIN-11 and some of its normal accessories, plus Firefox, BT e-mail and Norton protection:
MS Office for Windows XP (so 'Word', 'Excel', 'PowerPoint', possibly 'Access' too),
The HP Printer driver,
Only 2 general social-media accounts - but NOT Facebook or Twitter - plus a couple specific to my interests.
and some third-party programmes:
two of CAD, one measurements-units converter / calculator and one special geological survey tool.
None of these, except the Norton, are on subscription.
The PC came already loaded with WIN_10 which MS later un-obligingly changed to W11.
I bought 'Office for XP' and the two CAD programmes as single, up-front purchases.
The converter and survey tools were free from elsewhere.
There are no games, no wi-fi, no Bluetooth (is that a dental complaint indigenous to Artic regions?), no camera, no microphone, no entertainments accounts (films, music, TV).
