Gymme Multi Gym Timers gives you 4 countdowns at a time. You can pre set a different countdown time for each: it will be at your disposal with a tap.
You can set alarm and how many seconds before the end this alarm should sound so that you can reach your gym tool in time.
Gymme Multi Gym Timers is just a function of my other, wide range, training software: Gymme personal trainer.
