Whats the trick, you ask. Timers on AppStore - theres as many of them as stray dogs.
So, lets not quite true. We are, as you can see, specialised in fitness applications. We found that a simple and flexible timer (without advertising (hey Google)), visually clear and with loud sound (which is important in terms of training in the gym) - does not exist.
Well we create this timer. We hope you enjoy it.
P.S. Do NOT scold, BUT recommend (we will improve) - and all of us will be happy.
