I was using Android for many years and switched to iPhone few weeks ago.
- When I set alarm, I do not get notification how long it will take until the alarm will fire.
- When timer on Adroid ends it shows notification and it starts a stopwatch inside notification so I know how long after I turned it off. It has two buuttons close and restart timer. On iPhone it just shows that time is off.
- Calendar widget - if I want bigger widget I need to have it full with. On Android I have tall widget just on one half of the screen and I can scroll over events even go to other day without opening calendar app
