Egg timer? Reminder alarm? Alarm for a healthy sleep after dinner? Cooking Timer?
Originally, "Multi Timer" was planned as simple kitchen timer (originally "KITchen TImer", thus "Kitty"), but as it grew up, it became a universal timer app.
Do you want to:
* be able to run multiple timers concurrently, clearly arranged?
* be able to start timers with only one touch (from the homescreen, even the dock for immediate access)?
* manage pre-configured timers with own icons and sounds?
* have optimal use of different layouts of Smartphone and Tablet?
* see the remaining time of the next timer in the notification tray?
* have timer actions being read out aloud?
* ... and other nice-to-haves
My main point was: simple and fast handling, and ease of use.
(Android M and later: the app must be excluded from battery optimization to get a correct display of the remaining time!)
