Choose your bomb
Any bomb you pick runs for 1 hour. Three bombs are free to play, one more goes free each day, and the whole crew is ready whenever you want them.
Other timer lengths
One hour is the marathon. This free 1 hour bomb timer covers exams, project blocks, study sessions, screen-time budgets, and countdowns like “the guests arrive in one hour and this house needs a miracle.”
The fuse burns so slowly it reads as calm, which makes it a surprisingly good focus companion: the room can see time passing without feeling chased. The big digits stay readable from anywhere, and the timer keeps perfect time even when the tab is hidden.
For class periods that run shorter, the 30 minute and 20 minute bomb timers cover the usual blocks. And if an hour is somehow not enough, the +30s button can stretch a running timer even further.
