I used to use Chronology (from Treeness) to create a list of countdown timers. When the first countdown timer completed it would fire off the second timer, and so on. Chronology no longer works on the current version of iOS, and it's replacement, Chronoplan does not have the functionality to have the completion of one timer initiate the next timer in the list. I've tried HIIT-type timers such as Seconds, but it's fitness-centric and doesn't show me the list of timers the way Chronology did. Is there an app out there that comes close to Chronology?
