I realized I didn't use any apps from Apple. Mostly because I found these useless. Timers / alarms do not work properly due to Apple restrictions. And the rest is not useful or glitchy usually (uber, fb messenger). Some load forever (tesla related apps). Sound recording is not stable and too visual (I wanted to record important meetings for personal use, but big red circle scares people around). Notes (drafts) are very inconvenient on a small screen.
So ends up with: Alarm Timer Countdown World clock Music (volume and next) Wallet (credit card) Messages (sms, fb messenger, nest)
found useful integration with the maps (the sounds in the maps are turned off and this nags if turns are fine)
