Clockrift: Cron Simulator
Find DST & Overlap Risks
$0.99 · Designed for iPad. Not verified for macOS.
Map recurring jobs across local time, duration, frequency, DST transition windows, overlap, missed-run behavior, and ownership.
Clockrift is a local recurring-job rehearsal tool for developers, operators, data teams, and automation owners who need to reason about time before a schedule fails.
Screen recurring work against DST windows, duration, cadence, and the recovery semantics that schedulers often leave implicit.
