It has multi timer functionality. But why did it not allow all those timer to be Run. There are some parallel activities where i need to run both the timer to run. But it allows only one timer to run in the multiple timers
This is what u were looking for.
No-frills and does exactly what it says on the tin. Slim and robust.
It is so much easier to keep track how efficient I am and which projects demand extra time. Love the feature that enables you to manually adjust timers and checkpoints.
