Choose your bomb
Any bomb you pick runs for 30 minutes. Three bombs are free forever, and nine more are ready whenever you want the whole crew.
Other timer lengths
Thirty minutes is the long haul. This free 30 minute bomb timer covers tests, project work, deep-clean missions, and full chore rotations, with a fuse that burns slowly enough to feel calm and a finish that still lands with a bang.
For longer assessments, start the bomb and write checkpoint times on the board next to it. Students get the ambient countdown plus concrete milestones. The timer keeps perfect time even if the tab is hidden for a moment.
Need even more? The 1 hour bomb timer is the longest preset, and the Custom button accepts anything in between. For the opposite end of the scale, the 30 second timer handles lightning rounds.
